Devices sensitive to static
Introduction
Certain metal oxide semiconductor (MOS) devices embody in their design a thin
layer of insulation that is susceptible to damage from electrostatic charge. Such
a charge applied to the leads of the device could cause irreparable damage.
These charges can be built up on nylon overalls, by friction, by pushing the
hands into high insulation packing material or by use of unearthed soldering
irons.
MOS devices are normally despatched from the manufacturers with the leads
shorted together, for example, by metal foil eyelets, wire strapping, or by
inserting the leads into conductive plastic foam. Provided the leads are shorted
it is safe to handle the device.
Special
handling
techniques
In the event of one of these devices having to be replaced, observe the
following precautions when handling the replacement:
SAlways wear an earth strap which must be connected to the electrostatic
point (ESP) on the equipment.
SLeave the short circuit on the leads until the last moment. It may be
necessary to replace the conductive foam by a piece of wire to enable the
device to be fitted.
SDo not wear outer clothing made of nylon or similar man made material. A
cotton overall is preferable.
SIf possible work on an earthed metal surface. Wipe insulated plastic work
surfaces with an anti-static cloth before starting the operation.
SAll metal tools should be used and when not in use they should be placed
on an earthed surface.
STake care when removing components connected to electrostatic sensitive
devices. These components may be providing protection to the device.
When mounted onto printed circuit boards (PCBs), MOS devices are normally
less susceptible to electrostatic damage. However PCBs should be handled with
care, preferably by their edges and not by their tracks and pins, they should be
transferred directly from their packing to the equipment (or the other way
around) and never left exposed on the workbench.

Comparison
overview
The Horizon
macro
is a replacement for M-Cellt
2/6
base stations, and the
GSM/EGSM900 and DCS1800 Horizon
macro
variants are directly compatible
with M-Cell
6
. For example, a mixture of up to four Horizon
macro
and M-Cell
6
BTSs can be combined to form a single site, with either a Horizon
macro
or an
M-Cell
6
being in control of the other units. Since many customers are familiar
with M-Cell
6
, and will use Horizon
macro
with M-Cell
6
, equivalent components
are described in this section, to assist understanding.
The Horizon
macro
is a single cabinet, using reduced size and higher reliability
components. The plinth base fix points are the same as M-Cell
6
, though direct
replacement may require repositioning, to allow for adequate cabinet spacing.
The Horizon
macro
can have a stacking bracket fitted to enable CCB installation,
and/or to enable mounting a second Horizon
macro
.
Horizon
macro
and M-Cell
6
compatibility
A 24-carrier BTS site (in an 8/8/8 configuration) can be achieved by combining
four units as shown in Figure 1-5. This is the maximum BTS size. Each unit can
be either a Horizon
macro
or an M-Cell
6
. Either a Horizon
macro
or an M-Cell
6
can control the other three units; the MCU of M-Cell
6
and the MCUF of
Horizon
macro
being identical in control function.
An MCUF can be fitted into an M-Cell
6
and will then function as an MCU. An
MCU cannot be fitted into a Horizon
macro
. Figure 1-5 shows a schematic
diagram of the digital connectons in a four cabinet BTS site.

Structural
considerations
Adequate clearance must be provided at the front of the equipment for
operation and maintenance purposes. There must be adequate side clearance
(50 mm) to enable the door to open beyond 90° (see Figure 1-6). The door can
also stop at 95° and 130° , but this is only to protect the door, or give optional
additional operator space.
The cabinet ventilation entry can be solely from the bottom front of the cabinet.
This allows a cabinet to be placed against a wall. However, if the unit is placed
50 mm from back or side obstructions, such as wall or other cabinets, the
ventilation will be improved, and fan noise reduced.
Up to 100 mm rear space may be required for cables if using stacking bracket.
The foundation or structure on which the BTS cabinet is mounted must be of
sufficient strength to support a maximum gross weight of 130 kg for a single
cabinet or 280 kg for two stacked cabinets.
NOTE In seismically active areas, Motorola suggest using a
qualified structural engineer to assess frame mounting
requirements, such as floor construction, mounting
anchors, cell site construction and to provide a suitable
design for top frame support if a stacked configuration is
required.

Indoor temperature control system
Temperature
control
overview
The Horizon
macro
indoor cabinet contains equipment that has to be maintained
within the operational temperature range, to ensure correct operation of the
equipment and to guard against premature failure of the individual components.
The internal temperature is maintained within these limits by internal fans.
Cabinet over
temperature
control
Under overheat conditions, as the temperature rises above preset levels,
temperature sensors located in various areas within the cabinet provide alarms.
A further increase in temperature causes dual sensors, set at a higher threshold
temperature to initiate PSM and cabinet shutdown. The cabinet is restarted
when the sensors are reset by a substantial fall in temperature.
The CTUs have their own shutdown responses to overheating. The CTUs
shutdown at 92 _C.
850/900 MHz CTUs also have an internal 4 dB power reduction response to
overheating at 85 _C. 1800/1900 MHz CTUs have a 0.6 dB cut back at 70 _C, in
addition to the 4 dB power reduction at 85 _C.
The CTU shutdown response to overheating provides a second level of cabinet
protection, independent of the cabinet heat sensors.
Temperature
sensors
The three cabinet temperature sensors are located above the CTU
compartment (see Figure 2-7) and consist of the following:
SOne 70 _C sensor provides a cabinet overtemperature alarm when the
cabinet temperature exceeds planned level. The alarm is processed by
the alarm board and MCUF, and sent on to the OMC-R via the BSC.
STwo 85 _C sensors shut down the PSMs to protect the cabinet equipment
from heat damage. Both sensors must detect excess temperature for the
shutdown to take place; this reduces the risk of an unnecessary shutdown.
No prior notification of shutdown is given to the OMC-R, except for the
original 70 _C sensor alarm. This is because the MCUF and CTUs
immediately lose power and functionality.
Cabinet restart
after shutdown
The cabinet is restarted when the overtemperature condition initiating shutdown
has reset. The two 85 _C temperature sensors reset at 55 _C. This
re-establishes an earth point for the PSM internal detectors connected to the
cabinet heat sensors, which then reactivate the PSM outputs. The MCUF then
reboots as in a normal power up.

Fan operation
and reset
The fans draw in air from beneath the cabinet, and the air is expelled through
the door and top cabinet vents. The fans run continuously, and respond to
temperature changes to ensure adequate flow. The speed of each fan is
controlled by a heat sensor mounted on the fan hub.
Each fan has a reset button, for use if a fan has stopped or cannot start. Each
reset button is marked FRONT or REAR to identify the appropriate fan.
Filter option
and effect on
fans
The filter is an option and not essential in a clean environment. The single filter
is mounted under all the fan units. If clogged, fan airflow may be reduced,
straining fan motors and increasing fan noise.

Types and
overview of
PSM
There are two types of dc power supply modules (PSMs):
SNominal +27 V (negative earth input).
SNominal –48 V (positive earth input).
There is one type of ac PSM:
SNominal 120/240 V.
All PSMs have the same external appearance and are located in the same
positions. Different types are identified only by front panel labels.
The PSMs are fed from a backplane connector and use pulse width modulation
to generate output supply. A front panel switch (shown in Figure 4-2), disables
the output, reducing the input current as shown in Table 4-1.

Hold-up battery module
Introduction to
hold-up battery
module
The optional hold-up battery module provides short term backup power for one
ac powered Horizon
macro
indoor BTS cabinet. The hold-up battery module is
fitted in the PSM shelf within the CBIA main cage, in any empty slot or in place
of the redundant PSM. It connects to the Horizon
macro
indoor BTS through the
PSM slot backplane connector.
NOTE If the hold-up battery module is used in a Horizon
macro
cabinet with more than three radios fitted, power supply
redundancy cannot be supported.
Under normal operating conditions the hold-up batteries provide ten seconds of
backup power (at 25 _C) for a fully populated (six radio) Horizon
macro
indoor
BTS cabinet.
NOTE Due to the discharge characteristics of the internal
batteries, hold-up duration is reduced at temperatures
below 25 _C.
Figure 4-3 shows a view of the hold-up battery module, with LEDs identified.

Alarms
Alarms are generated by the open contacts of de-energized relays within the
hold-up battery module, (during normal operation the relays are energized and
the contacts closed). The contacts are rated for 1 A at 30 V. The alarms are
then passed to the Horizon
macro
alarm board, through the CBIA backplane, for
onward transmission to the OMC-R. These alarms are equivalent to the PSM
alarms.
The alarm signals generated are:
SOutput fail.
This alarm is triggered if:
– The enable pin is not correctly plugged into the backplane.
– The battery charger fails.
– The front panel enable switch is off.
– The batteries fail.
NOTE If a battery failure occurs, the batteries may have reached
the end of life. The hold-up battery module is disabled and
must be returned to Motorola for repair.
SInput fail.
This alarm is triggered if the external ac supply voltage drops below:
– 88 volts (110 V ac nominal systems).
– 150 volts (230 V ac nominal systems).
SOver temperature.
This alarm is triggered if the hold-up battery module temperature exceeds
50 _C.
Signals
The following signals interface with the Horizon
macro
backplane:
SEnable.
The output of the hold-up battery module is inhibited unless the ENABLE
signal pin is connected to the output return pin through the Horizon
macro
backplane.
SHold-up module ID.
The hold-up module provides a five bit TTL signal to the OMC-R that
allows identification of the hold-up module. This signal is available when
ac is present and during battery discharge and identifies to the OMC-R the
that a battery hold-up module is fitted.

description
The BPSM is a switching type dc/dc power converter that converts the cabinet
+27 V dc power to the following regulated dc outputs:
S+3.3 V ±1 % at 10 A (full load current)
S+5 V ±2 % at 10 A (full load current).
S+12 V ±5 % at 4 A (full load current).
S–12 V ±5 % at 2 A (full load current).
Internal BPSM circuits monitor the +3.3 V, +5 V, +12 V and –12 V outputs for the
following purposes:
SOutput voltage regulation.
SOver-voltage protection - provides shutdown if output voltage exceeds 1.1
to 1.2 times the rated output.
SOver-current protection - maximum output current has the following limits:
– 1.1 to 1.8 times full load rating of +3.3 V output.
– 1.1 to 1.8 times full load rating of +5 V output.
– 1.25 to 2 times full load rating of +12 V and –12 V outputs.
Circuit protection
Additional internal circuitry protects the BPSM:
SInput dc reverse polarity protection, achieved by an input series diode.
SThermal protection by automatic BPSM shutdown. Normal BPSM
operation resumes after BPSM temperature returns to a safe level.

Receive RF
hardware
Receiver RF hardware consists of the SURF module and optional Tx block
receive path, and the receive section of the CTU.
The SURF module provides bandpass filtering and low-noise amplification for up
to three sectors, with diversity receive antenna signals, together with switching
to CTUs.
CTU Rx role
The CTU provides the following receive functions:
SReceiver tuning (on a timeslot basis) to any receive channel frequency.
SDemodulation and equalization of the receive channel signal.
SMeasurement of the received signal strength indication (RSSI) and signal
quality.
SRecovery of received data from the demodulated radio channel.
SChannel decoding of the received data and processing of the recovered
signal. Traffic data is passed on to the MCUF for routeing to the MSC.
SDigital interface to the SURF module, which controls selection by the
SURF switch of the receive signals from the appropriate antenna.

Transmit (Tx)
RF hardware
Transmit RF hardware consists of Tx blocks in appropriate combinations to meet
requirements of antenna sharing for the transceivers.
CTU Tx role
The CTU provides the following transmit functions:
STransmit tuning (on a timeslot basis) for generation of any transmit
channel RF frequency.
SEncoding transmit data output.
SDigital modulation of transmit data onto the transmit radio channel signal.
SFinal RF power amplification and output power level control of the transmit
radio channel RF signal.
SWhen using a CCB, the output of control data to the CCB.
SChannel encoding of the data to be transmitted, interleaving signal and
traffic channel data, as defined by ETSI.
Rx/Tx single
antenna
duplexing
Duplexers allow a single antenna to be used for both transmit and receive
operations. Duplexers exist within several of the transmit blocks. Normally
duplexed RF signals are used through one antenna, with a second receive
antenna to provide diversity.
CAUTION If a single antenna (non-diversity) is required, the duplex
antenna RF receive cable from the transmit block must be
connected to the RxA path at the SURF. Simply switching
off diversity at the OMC-R without the correct SURF
configuration will cause a loss of reception.

RF overview
This section explains the RF functional blocks and additional RF loopback test
capability.
The terminology, functionality and optional capabilities are set out, as a basis for
understanding more detailed descriptions in RF module sections of this chapter.
RF main
component
explanation
The following description should be read in conjunction with Figure 5-1.
The RF equipment consists of three main blocks:
SThe CTU.
SThe SURF module.
SThe Tx block or alternatively CCBs.
CTU
The CTU can operate at 850 MHz, 900 MHz, 1800 MHz or 1900 MHz,
depending on the BTS variant ordered. It can receive two inputs, RxA and RxB,
from the SURF. These inputs are converted into digital voice/data. The two Rx
signals provide diversity of the Rx function from the MS (uplink).
The CTU also generates a Tx data signal, translated from received digital
voice/data, which is transmitted by cable to the Tx block for antenna
transmission to the MS (downlink).
The third (middle) port provides an RF loopback test signal capability, for
automatic transmission of RF test signals to the SURF.
SURF module
One of six variants of the SURF module can be installed in the Horizon
macro
indoor:
SSingle band 850 MHz SURF.
SSingle band 900 MHz SURF.
SDual band 900 MHz SURF.
SSingle band 1800 MHz SURF
SDual band 1800 MHz SURF.
SSingle band 1900 MHz SURF.
The single band SURF modules accept up to three pairs of antenna inputs, and
the dual band SURF modules accept up to four pairs of antenna inputs. The
SURF switches the inputs to the appropriate CTUs under the control of the
database via the MCUF. There are two inputs to each CTU for Rx diversity.
The SURF also contains loopback test circuitry, connecting with a test signal
from each CTU.

Tx block
There are up to three Tx blocks, each block serving two CTUs.
Tx blocks filter the transmit signal for the required Tx band. Tx blocks also use
filters to enable the Rx frequency signal to be passed to the SURF, if one
antenna is used for both Tx and Rx signals.
CCBs
Cavity combining blocks (CCBs) are an alternative to Tx blocks. CCBs combine
up to three CTU transmit paths. Two CCBs can combine up to six CTU transmit
paths. CCBs have no duplexing capability and must be connected to an
antenna via an external high power duplexer (HPD). CCBs cannot be used with
the GSM850 or PCS1900 BTS variants, or when SFH (see CTU frequency
Hopping) is required.
RF loopback
purpose
The loopback test function is primarily used to identify faults when the RF
system has failed. The loopback test function enables a diagnostic capability at
the OMC-R, by creating a test signal to identify if the fault is either:
SSoftware (that the OMC-R can correct).
SParticular hardware (CTU or SURF).
The result is a reduction in site assessment visits, and avoidance of
unnecessary visits when hardware is functioning correctly.
NOTE The RF loopback test feature available on the
Horizon
macro
, is not available on previous generations of
equipment.
RF loopback
hardware
The RF loopback test function is essentially a hardware capability built into the
CTU and the SURF. Software instructions activate the test hardware, to route
test signals through the RF system.
RF loopback
software
operation
When installed with suitable software, GSR5 or later, the OMC-R can operate
the loopback test functions, and receive the results of the tests.

Description of
RF test modes
The following description should be read in conjunction with Figure 5-1.
NOTE The RF test capability described requires software load
GSR5 or later.
The loopback test hardware picks up an attenuated signal by coupled link from
the normal CTU transmit signal.
The signal is mixed down to the receive band for testing the Rx functionality of
the SURF and CTU. Power to the loopback circuitry is automatically turned off
when the radio is in normal operation.
SURF test mode
The loopback signal is injected into the antenna receive path of the SURF by
coupled link. This tests the complete SURF and CTU Rx system path.
Test of CTU Rx circuitry
The loopback signal is injected directly internally into the Rx input of the CTU.
This tests the receive portion of the CTU.
VSWR test mode
The test signal, at Rx frequency, is injected into the antenna port through
coupled link on the SURF. Reflected power is monitored by the receive system
to calculate VSWR. Detection of a high VSWR may indicate the presence of a
cable or antenna fault.

CTU Tx
connector
The CTU Tx connector is a short SMA to SMA link to the base of the
appropriate Tx block or feedthrough plate.
NOTE The Tx cable has a 90° SMA connector at one end and a
straight SMA connector at the other end. The 90° end is
designed for connection to the Tx port of a CTU.
CTU Rx
function
The receiver part of the CTU accepts two amplified and filtered receive antenna
signals from the SURF module. These two signals are applied to inputs (branch
A and branch B) of the CTU transceiver board. Figure 5-5 shows a CTU
receiver functional diagram for one branch.
The input from the SURF module is filtered, amplified and down converted to
ensure the signal level and frequency range are correct for the next stage.
RSSI data (applicable only to GPRS and RACH bursts) is used for automatic
gain control (AGC) to ensure signal strength is correct for the intermediate
frequency (IF) stage.
Figure 5-5 CTU receiver functional diagram for one branch
The primary function of the IF is to filter and amplify the incoming signal.
The path is demodulated into quadrature signals and filtered by baseband
analogue filters. These signals are then digitized (I1/I2 data and Q1/Q2 data)
and made available to the equalizer for the purposes of receive synchronization
and data recovery.

modulator to create a Gaussian minimum shift keyed (GMSK) carrier at an
intermediate frequency (IF).

Figure 5-7 shows a functional diagram of the IF and exciter stages. The low
level modulated carrier is applied to a combination of analogue and digital
attenuators for RF power control. The power control data comes from the digital
sections of the XCVR. The output of the power control elements is further
amplified by an exciter chain to drive the power amplifier.
The GMSK modulated IF is filtered and applied to the input of a controlled gain
amplifier for transmitter pulse sloping (ramped). The ramped signal is filtered
and then mixed with the main transmitter injection and is upconverted to the
final transmit channel frequency.

CTU
uplink/downlink
Downlink traffic data flow
Downlink TRAU data from the MCUF is received by the TDM function then
routed to the CCCP function where it is encoded (cyclic, block, and
convolutional), interleaved, and encrypted to GSM recommendations. Signalling
messages are also received from the RSS processor and encoded. These
traffic and control messages are built into air interface frames and then routed
back to the MCUF via the TDM function for baseband hopping. The CCCP
calculates a BBH routeing word, which informs the MCUF of the radio link to be
the source of its post hopped data. The post hopped data is then once again
sent back down to the appropriate CTU where it is received by the TDM function
and passed to the EQCP function. The EQCP inserts midamble and guard bits
to the data bits and forwards the data on to the modulator for transmission. The
EQCP also programs the CTU for the correct RF channel and transmit power
level for this transmitted burst.
Uplink traffic data flow
Baseband uplink traffic and control data messages are received by the CTU
interface function and sent to the EQCP where they are equalized. The EQCP
also calculates timing advance and RXLEV information, which is forwarded to
the RSS process. The recovered data bits are forwarded into the CCCP
process, where it is de-interleaved, decoded, and decrypted into TRAU frames.
Control messages are passed to the RSS function, while TRAU frames are sent
to the MCUF via the TDM interface.

CTU frequency hopping
Overview of
CTU frequency
hopping
The CTU supports two types of frequency hopping, synthesizer frequency
hopping (SFH) and baseband frequency hopping (BBH). This section provides
an explanation of both types. In either type, the MS switches channels after
every transmit/receive (Tx/Rx) burst pair. The difference between SFH and BBH
is in the method by which channel switching is achieved at the BTS.
Synthesizer
frequency
hopping (SFH)
SFH uses the frequency agility of the CTU to change Tx/Rx frequency on any
timeslot (TS), without affecting other timeslots.
SFH can only be used with wideband combining.
With SFH, each TS is allocated a number of frequencies (max 64) over which to
perform the hopping. When determining the hardware requirement for CTUs
using SFH the following rules apply:
SA minimum of two CTUs are required per cell due to BCCH requirements.
Timeslot 0 of CTU 0 is used for the BCCH carrier as shown in Figure 5-10.
CTU 0 cannot use SFH. Only CTU 1 and additional CTUs can use SFH.
SHopping through the BCCH carrier (using the BCCH carrier frequency as
one of the SFH frequencies) is permitted except for timeslot 0. However,
the corresponding timeslot for the BCCH CTU will be switched off for this
period.
Figure 5-10 shows the minimum SFH requirement.

SFH example
not through
BCCH
CTU 0
In this example of SFH, CTU 0 provides the BCCH and cannot frequency hop.
CTU 0 has to transmit at maximum cell site power to meet the BCCH
requirement. Timeslots are used as shown below:
STS 0 = Combined BCCH TS (BCCH/CCCH/DCCH). Transmitted at
maximum cell site power.
STS 1-7 = Traffic channels, all non-hopping. All traffic channels transmit at
maximum cell site power.
CTU 1 and additional CTUs
CTU 1 and any additional CTUs provide SFH traffic channels as shown below:
STS 0-7 = Frequency hopping traffic channels. The frequency allocated to
the BCCH of CTU 0 cannot be used for frequency hopping purposes.

CTU 0
In this example of SFH, CTU 0 provides the BCCH and cannot frequency hop.
CTU 0 has to transmit at maximum cell site power to meet the BCCH
requirement. Timeslots are used as shown below:
STS 0 = Combined BCCH timeslot (BCCH/CCCH/DCCH). Transmitted at
maximum cell site power.
STS 1-7 = Unused timeslots transmitting dummy bursts for BCCH. All
channels transmit at maximum cell site power.
CTU 1 and additional CTUs
CTU 1 and any additional CTUs provide SFH traffic channels as shown below:
STS 0 = Frequency hopping traffic channel, but prevented from using
BCCH frequency.
STS 1-7 =Frequency hopping traffic channels, using all available
frequencies, including BCCH.
When the SFH selects the BCCH frequency, the CTU transmits at maximum cell
site power and the corresponding TS on CTU 0 is switched off for this period.

Baseband
frequency
hopping (BBH)
BBH requires all eight timeslots of the CTU Tx (downlink) at the same frequency.
In the Rx (uplink) direction, the frequency agility of the CTU is used to change
timeslot frequencies on a timeslot basis. The BCCH frequency is always
transmitted at maximum cell site power.
BBH can use either Tx blocks or CCB Tx combining equipment. The main
reason for using BBH instead of SFH is to enable frequency hopping when
using CCBs, because the mechanical tuning of CCBs is too slow for SFH.
The number of CTUs required to support BBH is equal to the number of
frequencies used.
NOTE BBH is not supported on GSM850 or PCS1900 BTSs.
BBH example
In Figure 5-11 MSs A, B and C are using TS 5 of CTUs 0, 1 and 2 respectively.
Figure 5-11 Diagram of BBH example using three CTUs
If the MSs are using cyclic hopping across ARFCNs 10, 20, 30 (an example
using EGSM900), each MS must transmit a burst of information each TDMA
frame (4.615 ms) on a different frequency. The data for the burst is received by
each CTU in turn (ARFCN 10, 20, 30), as shown in Table 5-3.

Transmit
The transmit is described by the following, as shown in Figure 5-12:
1. Traffic data from the network is passed through the NIU to the MCUF.
Within the MCUF an ASIC switches the data to CTU0 (the dedicated CTU
for this particular MS call example).
2. The CTU, having processed the data (channel coding, interleaving,
encryption and routeing information) then passes the data back to the
ASIC.
3. The ASIC follows the BBH routeing information to direct the data to the
next Tx CTU in the sequence of Table 5-3.
NOTE BBH differs from normal and SFH CTU Tx procedures, in
that the data is directed to CTUs in a cyclic sequence at
stage 3. Without BBH, stage 3 always routes data to the
original CTU.
Figure 5-12 shows a schematic diagram of an example of base band hopping.
Figure 5-12 Schematic of BBH example
Receive
Data from the MS is received by one CTU allocated to that MS (in this case
CTU0). The CTU will synthesize hop to the Rx signal. This ensures that the
handover and equalizers within only one CTU will be connected to a particular
MS.

SURF module
SURF module
overview
The sectorized universal receiver front end (SURF) module is located in a slot at
the rear of the cabinet top panel. Three connectors on the underside of the
module connect to the SURF harness which provides connectivity to up to six
compact transceiver units (CTUs). Antenna connections are located on the top
of the unit.
There are six types of SURF module available for the Horizon
macro
indoor BTS,
depending on the frequency variant:
S850 (MHz) single band SURF.
S900 (MHz) single band SURF.
S900 (MHz) dual band SURF.
S1800 (MHz) single band SURF.
S1800 (MHz) dual band SURF.
S1900 (MHz) single band SURF.
The single band SURFs contains three amplifier sections for connection to three
pairs of receive antenna inputs providing reception at the appropriate frequency.
The 900 dual band SURF contains three amplifier sections for connection to
three pairs of antennas providing 900 MHz reception and, being dual band, a
further amplifier section for connection to a pair of 1800 MHz receive antennas.
The 1800 dual band SURF similarly contains three amplifier sections for
connection to three pairs of antennas providing 1800 MHz reception and a
further amplifier section for connection to a pair of 900 MHz receive antennas.
Each amplifier section provides two receive outputs which may be directed to
any of the six CTUs, by the switch section. There are three connections to each
CTU; RxA, RxB and loopback test (L).
The two receive outputs from amplifier 0 are split and may be used as
extensions to other cabinets if required. These act as extended antenna
connections from antenna 0. The extension cables are connected to the
receive antenna connection ports on the SURF of the extension cabinet (which
is able to respond to each amplified signal as if it were a normal antenna input).

The single band SURF functional sections (Figure 5-14) consist of loopback,
filtering, amplification, splitting, digital processing and power selection.
Each section is duplicated for the second diversity path except for the digital
and dc power section which is shared by the two diversity paths. There are
three antenna pair inputs (ANT 0, ANT 1 and ANT 2) for each of the two
diversity branches (Branch A and Branch B). There are six outputs to the CTU
for each of the two diversity branches as well as one input from the CTU for the
loopback (LPBK) signal. There is also an output for an expansion cabinet for
ANT 0 on each branch.
The software database must be configured at the OMC-R to accept CTUs of the
same frequency as the single band SURF module in the cabinet.
The digital section switch, under the control of the database (signalled through
the MCUF and CTUs), routes the six amplifier outputs to the appropriate CTUs.
The digital and power supply section is also responsible for loopback switch
control, manual overrides, alarms and dc voltages.

description of
dual band SURF
modules
The dual band SURF modules provide front end filtering, amplification, and
matrix control of the RF receive signal between the antenna and the CTU. The
dual band SURFs each have three antenna pair connections providing main
frequency reception, and one antenna pair providing reception on a second
frequency. The two types of dual band (DB) SURF enable 900 CTUs to be
mixed with 1800 CTUs in any combination, up to the maximum total of six CTUs
per cabinet.
The software database must be configured at the OMC-R to accept 1800 CTUs
and 900 CTUs in the appropriate cabinet locations.
The dual band SURF functional sections (Figure 5-16) consist of loopback,
filtering, amplification, splitting, digital processing and power selection.
Each section is duplicated for the second diversity path except for the digital
and dc power section which is shared by the two diversity paths. There are four
antenna pair inputs (ANT 0, ANT 1, ANT 2 and ANT DB) for each of the two
diversity branches (Branch A and Branch B). There are six outputs to the CTU
for each of the two diversity branches as well as one input from the CTU for the
loopback (LPBK) signal. There is also an output for an expansion cabinet for
ANT 0 on each branch.
Digital codes are transmitted from the 900 CTUs and 1800 CTUs to the digital
section. The digital codes are dissimilar in order that 900 or 1800 CTUs can be
recognized and appropriate switching can be made to required antenna for
transmission and reception.
The digital and power supply section is also responsible for loopback switch
control, manual overrides, alarms and dc voltages.
The RF loopback test function is described in RF overview and RF test
function in this chapter.

Tx blocks overview
Introduction to
transmit blocks
Transmit (Tx) blocks are located in three positions in the basket above the
CTUs. There are four types of transmit (Tx) blocks, three of which are available
as 850, 900, 1800 or 1900 variants, and one dual band variant (for use with
900 MHz or 1800 MHz BTSs only).
CAUTION Unused Tx block locations must be covered with a
blanking plate for correct air flow and EMC shielding.
STDF (850, 900, 1800 or 1900) = Twin duplexed filter.
SDual band TDF (900/1800) = Dual band twin duplexed filter.
SDCF (850, 900, 1800 or 1900) = Duplexed combining bandpass filter.
SDDF (850, 900, 1800 or 1900) = Dual-stage duplexed combining filter.
These Tx blocks are cooled by airflow underneath. The DDF has fins, whereas
the TDF, dual band TDF and DCF do not.
Three types of plate can be located in the basket, one as blanking plate and two
to interface CTU Tx cables:
SBlanking plate. This ensures proper air flow and EMI shielding for an
unused basket Tx Block location.
SFeedthrough plate. This converts two SMA connectors to two N-type
connectors, used for connecting Tx cables to CCBs or DDFs.
SHybrid combining unit (HCU). This combines two SMA connectors to
one N-type, enabling two additional CTUs to be connected to a DDF.
One type of Tx unit is installed in the stacking bracket, and is connected to three
CTUs:
SCCB = Cavity Combining Block.
Two CCBs are required for the six CTUs of a filled cabinet. The CCB has no
duplexing capability and, if a single Rx/Tx antenna is used, connection must be
via an external high power duplexer.
CCBs are not currently available for use with the 850 MHz or 1900 MHz BTS
variants.

Overview of
DDF
The dual-stage duplexed combining filter (DDF) differs from the DCF in having a
second stage of combining to allow a third CTU Tx input. This third CTU Tx
input is connected to either:
SA feedthrough plate connector for a single additional CTU or
SAn HCU plate connector for combining two additional CTUs.
The DDF is located in the basket above the CTUs, and attached to the top
surface of the top panel using two M6 screws.

CCB
CCB overview
The Cavity Combining Block (CCB) has EGSM900 and DCS1800 variants. A
CCB consists of three independently tuneable cavity resonators, one per CTU.
NOTE CCBs are not currently available for the GSM850 or
PCS1900 BTS variants.
The CCBs are fitted in the CCB basket in the stacking bracket. The basket can
contain up to two CCBs, one for three CTUs. The two CCBs cannot be in
different cabinets because of the short phasing lead connecting the two.
Configurations where five or more carriers per sector are required could utilize
CCBs.
The recommended minimum channel spacing between cavities is 800 kHz.
There are two types of CCB:
SMaster CCB with Band Pass Filter (BPF) and control board.
SExtension CCB, identical to the master CCB but without the BPF and only
having a control board if redundancy is required.
Unlike the Tx blocks, the CCB has no duplexing capability. If a single Rx/Tx
antenna is used then connection to the CCB must be via an external high power
duplexer.
CCB control
board (TCB)
and set switch
The CCB control board is also known as the Transmit Antenna Transceiver
Interface (TATI) control board (TCB).
The CCB control board controls the interface to the CTU. This allows different
vendor CCBs to be installed without requiring amended CTU software.
The address of the control board is set manually using an 8 bit DIL switch, set
by Motorola. Data links are automatically set up.
TCB and link
redundancy
The redundant TCB has the ability to maintain the separated CCB, if the
inter-CCB link fails.

The CCB has three independently tuneable cavity resonators, as shown in
Figure 5-34. The cavities are narrow band devices which pass transmit signals
at the cavity tuned (resonant) frequency. The three cavity outputs are coupled
together.
The CCB cavities are tuned by software commands from the CCB control board.
Control data is sent from the CTU, via the coaxial cable, to the CCB. This data is
separated from the RF signal at the bias tee, and sent to the CCB control board.
The CCB control board then sends control signals through the control bus to the
motor control of the CCB cavity of the same transceiver.

micro
base control unit (µBCU) functionality. They are located in the bottom right side
of the CIBA maincage, and are electronically interconnected through the
backplane. Fibre optic connections are at the front of the appropriate modules.
Each digital module is assigned A (master) or B (redundant), with one BPSM
(µBCU Power Supply Module) for A and one BPSM for B. The alarm module is
not assigned to A or B, as it is supplied by both BPSMs for redundancy.
The master MCUF is assigned to A, and the redundant MCUF to B, each with
an associated FMUX.
The four NIUs are used by the operational MCUF, but two NIUs are powered by
BPSM A and two NIUs by BPSM B.
All slots are annotated with the legend of the appropriate module and located as
shown in Figure 6-1.

Digital module
and CTU
connections
The MCUF is connected to the CTUs in the same cabinet through the
backplane. Optional connection to CTUs in up to three additional cabinets (six
CTUs per cabinet) is by fibre optic links. FMUXs, two internal to the MCUF and
one half size module, convert the electronic data stream into a fibre optic signal.
An FMUX module in each extension cabinet converts the fibre optic signal back
to electronic data stream, for transmission to CTUs via the backplane.
The NIU modules convert signals for terrestrial E1 or T1 lines.

The main control unit with dual FMUX(MCUF) provides the site processing
functions, apart from RF functions of the transceiver. The MCUF also provides
switching for up to six network interfaces (via four NIUs) and up to 24
transceivers.
The cabinet may contain up to two MCUF modules, (one master and one for
redundancy). Each site and module has an electronic ID for remote
identification.
The MCUF provides the following functions:
SMaintenance and operational/control processing.
SCall processing (for example resource management and switching of
baseband hopping data).
SSwitching of traffic and control information.
STiming reference and network/BTS master clock synchronization.
SThe functionality of two FMUX.
SSupport of up to six transceivers via backplane in first cabinet and up to an
additional 18 transceivers via FMUX connections to other cabinets.
SSupport of up to six E1 or T1 circuits, via NIU modules.
SSupport of the CSFP function via the PCMCIA flash memory card.
Capability to

The MCUF combines the MCU function of M-Cell
6
with two FMUX modules. If
the MCUF is installed in an M-Cell
6
or M-Cell

Link to
redundant
MCUF
The link to the redundant MCUF is similar to a transceiver link, but does not
have the BBH capability, or the link delay measurement and compensation
facility. The 6.12 s, and 60 ms signals, are inserted into timeslots 8 and 16.
When the MCUF is in slave mode, timeslot and E1/T1 clock information is
extracted from the MCUF link and passed to the sync block.
The main processor HDLC link to the redundant MCUF can be routed in any
unused timeslot(s) of this link.
The ASIC can switch any timeslot on the redundancy link to any timeslot on any
of the other links connected to it such as the transceiver links, network links,
redundancy link or processor links.
Front panel
interfaces
TTY interface
A standard TTY interface is provided on the front panel, of 9.6 kbit/s (8 bits, no
parity, 1 stop bit (8 N 1)). A local maintenance terminal can be attached to this
port to use the MMI (Man Machine Interface) of the MCUF.
Debug and BDM ports
Two front panel ports are for Motorola factory and development use only:
SThe debug port, consists of a TTY connection to the sync processor to
access sync firmware, together with other connections to the ASIC and
main processors.
SThe Background Debug Mode (BDM) port is used for low level debugging
of the main processors.
FMUX fibre optic connections
There are fibre optic connections from the MCUF internal FMUX modules. The
fibre optic connectors enable connection to FMUX modules in other cabinets for
additional transceivers.
CAL port
The CAL port on the front panel of the MCUF can be used to calibrate the sync
block clock via MMI commands. The 8 kHz reference output is used in GCLK

PCMCIA interface
The PCMCIA card is located on the front panel of the MCUF, and is used for:
SCode Storage Facility Processor (CSFP) memory.
SRapid site initialization.
The PCMCIA socket is an industrial standard 68 pin single socket, fitted with an
ejector. The PCMCIA interface supports rev 2.1 type I and II cards.
The 20 Mbyte card can be write enabled, for upgrade of site information, or
disabled to protect card use for other sites or secure the site code.
Front panel
switches and
indicators
The front panel of the MCUF module has two reset switches as shown in
Figure 6-3:
SFULL is a hard reset (power up - removes software from the memory).
SCPU is a soft reset (this resets the MCUF main processors, but the
software remains in RAM).
A hard reset results in the software being reloaded to the DRAM in the same
way as normal power up.
NOTE During the CPU (soft) reset, pressing CPU reset again will
perform a hard reset. Pressing the CPU reset button twice
thus has the same effect as a hard reset.
The MCUF has two front panel LEDs (one green and one red) as shown in
Figure 6-3, with indications as shown in Table 6-2.
CAUTION When red and green LEDs are flashing, the boot code is
downloading into non-volatile memory for software
upgrade. Do not remove power or reset the cabinet until
downloading has been completed, as this will corrupt the
non-volatile memory. If boot code is corrupted, contact the
Motorola Customer Network Resolution Centre, requesting
the boot code restoration procedure and the appropriate
boot code file.

uses ECC protection. Memory protection is provided by the main processors.
Fast flash EPROM
The fast flash 1 Mbyte bank is used for bootcode and executive process code. It
has a fast access time (<75 ns), enabling direct execution. The bootcode is
factory set, and reprogrammed only in major software upgrades.
Slow flash EPROM
The slow flash 0.5 Mbyte bank is used for non-volatile data storage of diagnostic
data and module ID information.
Code loading
The boot and executive code, held in the fast flash EPROM, initiates the MCUF
on power up or reset. If a PCMCIA memory card is fitted, operational code may
be obtained and copied to the DRAM for execution. If no card or code is
available, the operational code is obtained from the BSC.
Before execution, the operational code held in DRAM is checked with code held
at the BSC. The BSC downloads any changed code objects to the DRAM.
After successful checking of the DRAM operational code, the code is executed,
and the PCMCIA memory card updated with any changed objects.
CSFP code loading
If a PCMCIA memory card is available,then a code storage facility processor
(CSFP) function can be supported. A new software load can be downloaded in
the background, without any reduction in service, and stored on the PCMCIA
card.
Once the complete load has been transferred to the PCMCIA card, a code swap
can be initiated. The site is reset and the new software brought into service (<10
minutes). As a precaution, the old version is held on the PCMCIA card to
support a roll back to the original version if required.

ASIC
functionality
The Application Specific Integrated Circuit (ASIC) provides central switching
capabilities for the MCUF. It is capable of supporting up to 24 transceivers,
together with up to six network interfaces and two links to the on-board
processors, one link to the sync processor and a link to the redundant MCUF.
The link to the sync processor is used for code loading purposes only. The
ASIC supports baseband hopping across the 24 transceiver links.
The ASIC provides interface features associated with the transceiver links,
these include synchronization features to allow for delay in the link to the
transceivers, and the necessary framing and encoding to support the link.
All of the serial links into the ASIC are internal lines (I lines), 125 ms framed,
with 32 eight bit timeslots per frame.
ASIC transceiver link features
The ASIC interfaces to a maximum of 24 transceiver links. The ASIC can switch
any timeslot on any of the transceiver links to any timeslot on other links
connected to the ASIC; transceiver links, network links, MCUF redundancy link
or processor links.
The ASIC provides the following features associated with the transceiver links:
SLink advance/delay compensation.
The ASIC will continually measure the round trip delay on each transceiver
link to calculate a timing advance for each link. The link advance is
applied, and can be adjusted, by the main processor via the processor
parallel interface.
SBBH data switching.
BBH switching is performed automatically on any timeslot configured as
BBH data. A single timeslot from the transceiver is selected for BBH
routeing information, and defines which transceiver link (0-23) should be
used for downlink.
STiming reference insertion.
The ASIC receives timing pulses from the sync block and inserts the
appropriate bits into the transceiver downlink synchronization and framing
timeslots. The sync block will provide a version of the 6.12 s and 60 ms
signals that is advanced by 125 ms for this purpose.
SManchester coding/decoding.
The transceiver links are all Manchester coded/decoded by the ASIC. This
function can be switched on or off (default on) on a per link basis. The
disable feature is for applications outside of the MCUF module.

ASIC/network and processor link switching
The ASIC supports a maximum of six network links and two main processor
links. The data to/from these links can be switched to/from any timeslot on other
links connected to the ASIC.
The two links to the main processor allow it to route HDLC and other links to the
appropriate place:
S24 HDLC timeslots for the BCF RSS channel to each transceiver.
SFour timeslots for NIU control channels (two local, two redundant).
SSync processor code load channel.
STwo channels for RSL links.
SOne HDLC channel occupying up to three timeslots to the redundant
MCUF.
Sync block
functionality
The sync block is controlled via the parallel interface of the main processors.
The sync block is responsible for site synchronization functions. It generates all
required local references from a high stability local clock source. This clock
source may also be locked to the incoming network clocks.
The sync clock source is in the form of a crystal oscillator (OCXO) which warms
up for phase locking in 4 minutes, and achieves frequency stabilization in 15
minutes.
Site frame reference generation and re-timing includes:
S2.048 MHz - For serial communications.
S16.384 MHz - For FMUX communications.
S125 ms - For NIU framing and transceiver framing.
S60 ms- For transceiver GSM timing.
S6.12 s - For GSM superframe.
The reference clocks available to the sync block are:
SSix network extracted clocks (E1/T1 source via NIUs). Any of the NIU
modules under control of the MCUF can extract a reference clock from an
E1/T1 link and pass to the Sync block.
SCAL port. The CAL port can be used to calibrate the sync block clock via
MMI commands. The reference output provides a monitoring point.
SRedundant MCUF link.

The PLL uses the selected reference signal as the loop reference clock. It
includes an OCXO accurate to 0.05 ppm, a phase comparator and a loop filter.
The PLL has the following operating modes:
SWarm-up
The PLL is open loop and using the calibration frequency, but the OCXO
is not yet warmed up.
SSet frequency
The PLL is open loop and using the calibration frequency, and the OCXO
is warmed up.
SFast tune
Closed loop with wide filter for coarse locking to the reference (extracted

SFine tune
Closed loop with narrow filter for accurate locking to the reference
(extracted from network clock).
When in fine tune closed loop mode, the accuracy is 0.01 ppm.
Sync block code load
The sync block controller has a dedicated 2.048 Mbit/s serial link into the ASIC
enabling a 64 kbit/s HDLC channel to the main processors for code loading.
The sync block includes 256 kbytes of flash EPROM used to store:
SBoot code.
SOperational code.
The boot code, which cannot be altered, queries the main processors on the
current version of the sync operational code.
If the stored operational code is the correct version, the boot code will move the
operational code to RAM and execute the code.
If the query results in the need for new operational code, the sync processor will
download the operational code from the main processors via the ASIC to the
RAM in the sync block.
After a successful download, the boot code programmes the flash EPROM with
the new operational code and runs the operational code in RAM.
GSM counters
The following counters are provided:
SGSM frame incremented every 4.615 ms, range 0 to 1325.

Integral MCUF
FMUX
functionality
The equivalent function of two FMUX modules exists integral to the MCUF,
enabling two extension cabinets to be connected. To enable total of four
cabinets to be joined together as one BTS site, an FMUX module is also
required in the master cabinet to connect the third extension cabinet. A single
cabinet site has no need for the FMUX functionality, because the MCUF
connects with the cabinet CTUs through the backplane.
Each fibre optic multiplexer (FMUX) function multiplexes and demultiplexes six,
full duplex, transceiver links to one (TX/Rx) pair of fibre optic cables. This
enables up to six transceivers in a single extension cabinet (either
Horizon

Each FMUX fibre optic link is full duplex 16.384 Mbit/s. The FMUX optical link is
capable of driving up to 1 km.

NIU
Overview of NIU
The network interface unit (NIU) module provides two E1 or two T1 termination
links to the terrestrial network. The NIU E1/T1 outputs are connected to a T43 or
BIB board, depending on the impedance matching requirement of the customer
terrestrial circuits.
There are two types of NIU board, one for E1, one for T1. The NIU layout is
common to both E1 and T1, the only differences being in the associated crystal
oscillators and line matching resistor values.
An on-board NIU control processor provides network interface configuration and
supervision, controlled by the MCUF.
NIU locations
The cabinet may contain up to four NIU modules in the digital module shelf, as
shown in Figure 6-1. Two NIUs are located in the master (lower) part of the
shelf. Two NIUs are in the redundant (upper) part of the shelf, though these
upper NIUs are also used for non-redundant purposes.
An NIU in slot A0 supports two E1/T1 links.
An NIU in slot A1 supports one E1/T1 link.
An NIU in slot B0 supports two E1/T1 links.
An NIU in slot B1 supports one E1/T1 link.

processor
The control processor interfaces to timeslot 0 of link 0 from each connected
MCUF.
The processor uses 512 kbytes of flash EPROM for boot code. operational code
storage and module ID. Code is executed directly from the Flash EPROM. The
boot code can be overwritten under control of the MCUF, if required.
The processor also has an on-chip 1 Mbyte of DRAM.
TTY ports
The processing section provides two TTY ports for Motorola debugging
purposes only.
Resets
The processor is capable of soft resetting itself. The front panel reset causes a
hard reset of the entire board. Power-on also resets the processor.
The MCUF is able to reset the NIU via a message on the HDLC link.
NIU/MCUF
framing and
clocks
The control processor is supplied with a clock from an on-board crystal
oscillator, which has an output enable pad for test purposes. The framer
devices also have their own crystal oscillators on-board.
The framer devices provide the decoded and jitter attenuated receive data, for
passing to the MCUF.
The framer devices also extract a clock signal from an E1/T1 link, which is then
passed to the MCUF synchronization circuit. At the MCUF, this signal is used to
phase lock a local 16.384 MHz clock signal. Once phase locked, three reference
clock signals are provided for NIU use:
SREF 2.048 MHz clock signal.
SREF 6.12 s clock signal.
SREF 125 ms clock signal.
The NIU transmit and receive framing is controlled by this 125 ms reference
pulse received from the MCUF.

Distance
measurement
The NIU provides the ability to perform network distance delay measurement on
either of the two network links. Measurement can only be performed on one link
at a time.
Three modes of operation are possible:
SMode 1. A pattern is transmitted in a selected network timeslot and the
corresponding receive timeslot is monitored for its return. The delay is
measured to an accuracy of ± 488 ns. The pattern is transmitted on the
6.12 second reference signal.
SMode 2. The receive link is monitored for the pattern. When received the
pattern is transmitted back in the next frame. The time between receipt
and transmission of the pattern is measured to an accuracy of ± 488 ns.
SMode 3. The receive link is monitored for the pattern. When it is detected
a strobe is generated for the MCUF sync block.
Radio signalling
links (RSLs)
The radio signalling links (RSL) to the BSC from the main processor on the
MCUF are 64 kbit/s LAPD links. The LAPD encoding of this RSL data is
performed on the NIU by the NIU control processor.
The RSL links between the MCUF and NIU must be sent as follows:
SRSL link 1 is embedded in the NIU control link; that is, it will be in timeslot
0 of link 0 to the NIU. This link is important for initialization.
NOTE When the NIU is on a network link to a BSC or another
BTS, the RSL can be placed on either link on any default
timeslot other than zero.
SRSL link 2 is on a different timeslot from that used for the network
connection.
The NIU supports a maximum of two RSL links. The RSL links may both be on a
single network link or shared between the two network links.
The NIU hardware supports switching for 64 k and 16 k LAPD channels.
T1 NIU need to
set link type
T1 NIUs and E1 NIUs cannot be interchanged. A T1 link line consists of 24
timeslots as opposed to 32 timeslots for an E1 link line. A T1 link generates
specific T1 alarms, referred to as Red alarms. A T1 NIU supports the same MSI
type of device transitions as an E1 NIU.
The OMC-R operator should set the link type or it will default the site to an E1
system. In ROM it is set by a ROM-only MMI command. In RAM it is a database
parameter set by a chg_element command.
The RSL default timeslots are the same for a T1 NIU and an E1 NIU. The basic
mechanism for communicating and configuring is also the same.

FMUX module
Overview of
FMUX module
The fibre optic multiplexer (FMUX) module multiplexes and demultiplexes six,
full duplex, transceiver links to one (TX/Rx) pair of fibre optic cables. This
enables up to six transceivers in a single extension cabinet (either
Horizon
macro
or M-Cell
6
) to be linked to the master cabinet.
The FMUX module has two modes of operation:
SWorking in conjunction with the MCUF to multiplex transceiver links to/from
a third extension cabinet.
SOperating in the extension cabinet to supply the transceivers in that
cabinet.
To enable a total of four cabinets to be joined together as one BTS site, an
FMUX module is required in the master cabinet to connect the third extension
cabinet. A single cabinet site has no need for an FMUX module, because the
MCUF connects with the cabinet CTUs through the backplane.
Two FMUX modules may be fitted in the digital module shelf, one for the master
MCUF, and one for the slave. An extension cabinet only requires one FMUX to
connect to six transceivers within the cabinet, (plus one for redundancy if
required).
Each FMUX fibre optic link is full duplex 16.384 Mbit/s. The FMUX optical link is
capable of driving up to 1 km.

explanation
The MCUF transmits and receives a 2.048 Mbit/s data stream link to each
operational transceiver. In the master cabinet this is achieved by the backplane,
without using an FMUX.
If the transceiver is in an extension cabinet, the master cabinet FMUX combines
the data stream with up to five others (see Figure 6-9), and then converts the
electronic signal to fibre optic, for onward transmission to the extension cabinet.
At the extension cabinet, another FMUX converts the fibre optic signal back to
electronic form, for transmission to the transceivers.
The data stream return from the extension cabinet is a reverse of the above.
The multiplexer/demultiplexer can support up to six transceiver links. It uses a
16.384 Mbit/s Manchester encoded serial data link organized as 256 x eight bit
timeslots in a 125 ms frame. Manchester coding is used to detect errors,
indicated at timeslot zero for each transceiver, enabling error correction at the
other FMUX.

Cabinet weights
The weights of the fully populated cabinets are listed in Table 1-4.
CAUTION Consider future expansion. Another cabinet may be added
by stacking on top of the existing cabinet. This, if used
with stacking units on both, each with CCBs, and
associated cables, could result in a total weight of 280 kg.
Ensure floor is capable of supporting this weight.

Power
requirements
The power requirements of cabinets depends on the configuration. Indoor
cabinets require either ac or a positive or negative earth dc supply.
Power consumption (dc and ac)
Table 1-6 lists typical and maximum power consumption values
Table 1-6 Power consumption of full cabinet, including digital redundancy
Typical measured consumption Maximum power consumption
1400 watts 1700 watts
NOTE Maximum power consumption figures are theoretical
values derived under extreme conditions and are affected
by variables such as temperature, component tolerances,
transmission power and supply voltage. although these
figures must be considered when planning site power
requirements, typical measured consumption values will
be lower.
Cabinet power supply requirements
WARNING All cabinets and supply cables must be protected by a
fuse or circuit breaker selected in accordance with national
and regional wiring regulations.
Table 1-7 lists the power supply requirements for the different power supply
options.
Table 1-7 Main indoor cabinet power supply requirements
Nominal voltage Voltage supply
range Current supply maximum
+27 V dc (negative earth) +20 to +30 V dc 64 A (at nominal voltage)

120/240 V ac (50 – 60 Hz) 88 to 264 7.5 A (at nominal voltage)
NOTE Voltage transients must be less than 35 V peak amplitude
(never below 0 V). Ripple and noise must be less than
200 mV p-p (30 mV rms) over 10 Hz to 14 MHz. Voltage
application stabilization must be within the specified range
in less than 1 second.

Structural
considerations
Adequate clearance must be provided at the front of the equipment for
operation and maintenance purposes. There must be adequate side clearance
(50 mm) to enable the door to open beyond 90° (see Figure 1-1). The door can
also stop at 95° and 130°, but this is only to protect the door, or give optional
additional operator space.
The cabinet ventilation entry can be solely from the bottom front of the cabinet.
This allows a cabinet to be placed against a wall. However, if the unit is placed
50 mm from back or side obstructions, such as wall or other cabinets, the
ventilation will be improved, and fan noise reduced.
Up to 100 mm rear space may be required for cables if using stacking bracket.
The foundation or structure on which the BTS cabinet is mounted must be of
sufficient strength to support a maximum gross weight of 130 kg for a single
cabinet or 280 kg for two stacked cabinets.
NOTE In seismically active areas, Motorola suggest using a
qualified structural engineer to assess frame mounting
requirements, such as floor construction, mounting
anchors, cell site construction and to provide a suitable
design for top frame support if a stacked configuration is
required.

Waste material
on site
Clear waste material from the site on completion of the job, unless otherwise
indicated by the customer.
WARNING Do not burn waste material, as packaging might give off
toxic gasses.
Rural sites
It is the responsibility of the senior member of the team to ensure that all
personnel on site are aware of all applicable national and regional
environmental regulations or codes of practice and, especially with respect to
water authority sites, any relevant health regulations.
Adhere to these points:
SGuard against all risk of fire.
SFasten all gates (remember site visits could be traced back if a complaint
is made).
SLeave no litter.
SDrive carefully on country roads and observe speed restrictions at all
times.
SKeep to the paths/tracks across farm land.
On site safety
All personnel must:
SEnsure that under no circumstances should anyone move cabinets without
assistance. Cabinets must be safely positioned at all times.
SWear supplied safety helmets when antenna or overhead work is in
progress, and when local regulations require them.
SWear supplied safety goggles and dust masks when drilling. This is
particularly important when drilling overhead ironwork.
SWear supplied ear protectors while drilling is in progress.
SWear approved safety footwear when moving heavy equipment.
Stop any work that you are supervising should any person in your team not be
properly protected, or be unaware of safety requirements.
When installing cable ties, even temporarily, cut the excess or tail properly. This
is to prevent sharp edges inflicting injury when not cut flush with the locking
edge.

The base site structure should be designed to meet accepted cellular system
specifications. Additionally, the site must meet the environmental and electrical
operating criteria.
Site
requirements
The customer should provide secure access free from unauthorized personnel,
ample protection from fire, and adequate lighting and clearance at the front and
rear of the equipment for operation and maintenance. Additionally, four cable
ducts with sufficient space for communications cables, mains cables, earth
cables, and antenna RF cables should be provided.
Site access
The site access road and equipment receiving area must be constructed of
asphalt, concrete, or other suitable load bearing aggregate capable of
supporting the transportation vehicle and the cabinet.
NOTE Ensure the unloading area is clear of standing water,
fallen leaves, mud, and building debris.

Equipment delivery and unpacking
Delivery and
packaging
overview
Before the cabinet equipment arrives, installation personnel should designate
an area at the site where the equipment can be unloaded. This area should also
be suitable for unpacking the equipment. Consult with the heavy freight or
moving company and the owners of the building (if applicable) to select this
area.
CAUTION The cabinet equipment should be delivered to the site
while still contained in its packaging. This is to protect the
cabinet in transit and from moisture.
The equipment should be carefully delivered to the site by the freight company,
along with the necessary moving dollies and padding. Use the dollies and
padding to move the equipment from the unloading area to the installation point.
NOTE Keep all paperwork attached to packaging, or found inside
cabinet.
Packaging crate
The cabinet equipment is shipped in a crate of a similar construction to that
shown in Figure 2-2.

Installing cabinet plinth
Overview of
foundation and
plinth with
diagram
An indoor cabinet is supplied with a plinth, into which the cabinet structure is
located. This plinth can be used on a smooth, level concrete floor, or other
strong supportive construction. In addition the plinth is used in conjunction with
the stacking bracket in stacked cabinet configurations. The plinth ensures
correct weight distribution, and requires four M12 mounting or anchor bolts to
hold it firmly in position.
WARNING The cabinet must be bolted to the floor using the supplied
plinth. This prevents danger from toppling, if a stacking
bracket is ever added together with a second cabinet on
top. The plinth also reduces fire hazards. NEVER install
the cabinet without the plinth, and ALWAYS bolt the plinth
to the floor. Ensure the selected bolts are suitable.
The plinth is first fitted to the floor, then the cabinet is slid into the plinth and
bolted to the plinth. Figure 2-3 shows the plinth with locations for both floor
attachment and cabinet attachment.

The recommended length of the M12 steel anchor bolts is 105 mm minimum.
This is to ensure adequate strength if stacked cabinets are installed.
Installing the
plinth
If the cabinet is a direct replacement for existing Motorola M-Cell
6
, BTS4 or
BTS6 units, the cabinet can be mounted in place using the existing fixing holes.
Only use existing holes if sufficient space exists for the new configuration (see
Site requirements and considerations).
If the installation is new, the concrete floor must be drilled to accept M12 anchor
bolts. Washers and bushes are supplied, but the M12 steel bolts are supplied
by the customer.
1. Move the cabinet plinth to the selected mounting position. Consider future
as well as present space requirements (see Site requirements and
considerations).
2. Mark the positions of the four mounting holes in the base of the plinth.
These are in the form of four square holes in the middle of the plinth.
3. Move the plinth well away from the mounting position.
WARNING Wear safety glasses and a dust mask when drilling holes.
CAUTION Drilling concrete flooring produces cement dust, which is
harmful to equipment and wiring. Protect the cabinets and
any nearby equipment from dust. Use a tarpaulin, cloth, or
plastic sheeting to cover exposed equipment. Clean up
any accumulated debris from the anchor installation
carefully before exposing the equipment. Use drilling
equipment suitable for cutting steel reinforced concrete.
4. Drill out the four holes to a depth and clearance for an M12 anchor bolt,
using the plinth as a template.
5. Fit the M12 mounting anchors to the holes in the floor.
6. Position the plinth over the mounting anchor holes.
7. Fit the anchor bolts with the supplied bushes and washers, through the
plinth floor, to each anchor.
8. Tension up the anchor bolts and then check for alignment and level using
a spirit level.
9. When satisfied that the plinth is correctly aligned, torque the bolts to the
correct value for M12 bolts (see Site requirements and considerations
in this chapter).

68P02902W08-B
Tx connection
to CCB via
feedthrough
plates
If CCBs are used instead of Tx blocks, the Tx cables are connected through an
N-type to SMA feedthrough plate. This plate converts the normal Tx block SMA
connector underneath to an N-type connector above.
RF connection
principles
The primary receive path is connected to the A branch of the SURF module,
either directly or from the Rx connector on the Tx block in non-diversity
configurations. The diversity receive path is connected to the B path on the
SURF. This is normally duplexed with the transmit signal on a single antenna,
and fed to the SURF from the Rx connector on the Tx block. Within any single
cabinet the lowest numbered sector is normally connected to amplifier 0
connections, and higher numbered sectors to amplifiers 1 and 2 as appropriate.
For example, sector one is connected to SURF connectors 0A and 0B, sector
two to 1A and 1B, and sector three to 2A and 2B. However, if a sector is split
between two cabinets, the split sector antennas must be connected to amplifier
0, (this is the only path with connection to the extension ports). Extension ports
must be connected to the correct branch at the destination cabinet.
The transmit path feeds from the CTUs to the Tx block or feedthrough plate
immediately above. Two signals are combined in most Tx blocks. A third signal
can be combined using a feedthrough plate and the third input of a DDF. The Tx
blocks then duplex the Tx signal with the diversity Rx signal, before feeding to
the antenna.
Rx/Tx single
antenna
duplexing
Duplexers allow a single antenna to be used for both transmit and receive
operations. Duplexers exist within several of the transmit blocks. Normally
duplexed RF signals are used through one antenna, with a second receive
antenna to provide diversity.
CAUTION If a single antenna (non-diversity) is required, the duplex
antenna RF receive cable from the transmit block must be
connected to the RxA path at the SURF. Simply switching
off diversity at the OMC-R without the correct SURF
configuration will cause a loss of reception.

Suggested RF configurations
Overview of
configuration
diagrams
The following series of RF configuration diagrams show suggested ways of
connecting together Horizon
macro
SURF and Tx blocks to meet different
operational requirements. The series of diagrams is by no means exhaustive,
and numerous alternative configurations may be adopted to achieve the same
aim.
Each Horizon
macro
cabinet is represented by a SURF module and three Tx
blocks. Interconnecting cables are identified by a label; N01, 2, 3 or 4. Further
details of each cable type are shown in Table 2-3. Antenna connecting cables,
not supplied as part of the Horizon
macro
equipment, are shown as dotted lines.
With the exception of Figure 2-33 and Figure 2-34, the diagrams are applicable
to GSM850, EGSM900, DCS1800 or PCS1900 single band operation, although
only the 1800 SURF module is illustrated.
NOTE Dual band 900 and 1800 SURFs are available, but 850
and 1900 SURFs are only available as single band.
Figure 2-33 shows one way of achieving dual band operation using two
Horizon
macro
cabinets. A single band 1800 SURF is installed in one cabinet
and a dual band 900 SURF in the other. Figure 2-34 shows another, using one
of each type of dual band SURF.
Diversity is assumed in the majority of RF configuration diagrams shown here,
Figure 2-15 being the exception. Other non diversity configurations can be
derived from this figure by ensuring that the single receive path is always
connected to branch A at the SURF module.
Digital connections
Digital connections between cabinets are not shown in the following diagrams.
Fibre optic cables used to provide digital connections between cabinets are
described in Connecting fibre optic cables.
Depopulated site configurations
The purpose of a depopulated site configuration is to allow customers to provide
a future expansion capability, at the time of installation. The diagram showing
the final target configuration is to be used to connect Tx blocks, SURF and

Connecting fibre optic cables
Location of
fibre optic
connections
WARNING Do not look directly into a fibre optic cable or the data
in/out connectors of the FMUX or MCUF, with or without
the use of optical aids. Laser radiation can come from
either the data in/out connectors or unterminated fibre
optic cables connected to data in/out connectors.
In an installation configuration with more than one Horizon
macro
indoor cabinet,
fibre optic connections are used to link the MCUF in the master cabinet to the
extension cabinets. A maximum of three extension cabinets can be added to the
master cabinet.
Connections from the master cabinet are provided by three fibre optic
multiplexers (FMUXs). Two are located integral to the MCUF, and the third is a
separate module located in the slot next to the master MCUF. Additional
redundant modules may be installed for both MCUF and FMUX modules.
Extension cabinets have only a single FMUX, with optional redundancy, for fibre
optic connectivity to the master cabinet.
Tx and Rx data connections to the MCUF and FMUXs are located on the front
panel of each module.
Three different types of fibre optic cable, coloured orange and terminated with
ST fibre connectors, are available for use. These are described in Table 2-4.
Table 2-4 Extension cabinet fibre optic cables
Order

SVKN1244 5.6 m long connects master cabinet to first extension
SVKN1245 7.6 m long connects master cabinet to second extension
SVKN1246 7.6 m long connects master cabinet to third extension
Care of fibres
Optical fibre cables contain an inner core, which is a strand of glass coated by a
cladding (sometimes in two layers), and an outer protective sheath which
provides mechanical protection.
The fibre acts as a light waveguide. In order for the link to work correctly light
must be propagated with minimal losses from end-to-end of the fibre. A number
of problems can prevent this from happening, resulting in a potentially faulty link.
Care must be taken to ensure that the conditions that follow are met.

CONTROLLED INTRODUCTION
68P02902W08-B
Minimum bend radius
All optical fibres have a minimum bend radius. This represents the smallest
circle that is allowed to be formed from a loop of fibre, that is how tight it can be
coiled, looped or bent.
CAUTION Under no circumstances should fibres be bent tighter than
the minimum bend radius.
If fibres are bent tighter than the minimum bend radius then two possible effects
can happen:
SExcessive light loss can occur from the outside of the bend, resulting in a
loss of performance.
SThe fibre can fracture due to microscopic imperfections in the surface.
This type of break is invisible externally. If such a break occurs, excessive
light loss would be permanent and light would be scattered and reflected
from the break in the fibre. Returning the fibre to straight will not help and
the whole assembly will require replacement.
For glass fibres (orange or green outer sheath) the long term minimum bend
radius is approximately 30 mm.
Figure 2-35 illustrates the minimum bend radius for fibre optic cables.
30 mm
FIBRE OPTIC CABLE
Figure 2-35 Minimum bend radius of 30 mm
If the fibre is under tension (being stretched), the bend radius should be much
larger, at least doubled. This is because the tension in the fibre can increase the
possibilities of damage.
If in doubt about the radius, the fibre should be allowed to form its natural bend
radius by allowing it to bend under gravity only. This natural bend radius is
normally greater than 30 mm.

Protecting fibres and connectors
To maintain good light transmission through the fibre optic link it is essential to
maintain cleanliness of the connector end surfaces and/or bare fibre ends.
At all times when fibres are not connected into the system, the connector
protective caps (normally red) should be fitted and kept in place. This is
especially important when routeing fibres during installation.
Cleaning fibres and connectors
Cleanliness of fibre terminations and connectors is essential. If cleaning of
contaminated optical components is required, then all areas should be wiped
gently with a lint free cloth soaked in a suitable cleaning solution. Care should
be taken to ensure the ends of the fibres are not scratched in any way, and are
completely dry before reconnection.
Connecting glass fibre cables
Fibre-ST connectors are used to terminate the fibre optic cables. These are
push fit and should not be tightened when connecting. Table 2-5 shows the fibre
optic interconnections between master and extension cabinets in multiple

To connect fibre optic cables between master and extension cabinets in multiple
cabinet sites.
1. Open master and extension cabinet doors and remove hoods, (if fitted).
CAUTION Under no circumstances should fibres be bent tighter than
the minimum bend radius.
2. Route the appropriate length extension cabinet fibre optic cable from the
digital module compartment of the master cabinet, through the aperture in
the right side of the CBIA cage, to the top section of the cabinet.
CAUTION Under no circumstances should any tools, such as pliers,
be used to connect ST fibre connectors.
3. Connect the push fit ST connector of the fibre optic cables to the
appropriate ports on the master MCUF, or master FMUX module, front
panel (see Table 2-5).
4. Route the fibre optic cable to the extension cabinet, following existing
cable layout as far as possible.
5. Pass the fibre optic cable through the fibre optic cable hole in the cabinet
top section to the extension cabinet FMUX.
6. Connect the push fit ST connector of the fibre optic cables to the data
ports on the extension cabinet master FMUX front panel.
7. Repeat steps 2 to 6 for digital redundancy MCUF and FMUX, if fitted.

WARNING Use the earth stud, located on the interface panel on the
top of the cabinet, to earth the cabinet.
Do not daisy chain cabinet earths together.
Cabinets must be earthed with a conductor capable of
carrying the full fault current of the overcurrent protection
device.
Do not make input power connections at the main power
source at this time. Connecting input power is the final
installation procedure in this chapter.
Power specifications can be found in Chapter 2 Site requirements and
considerations.
Cable routeing
CAUTION Ensure that covers are fitted to any unused connectors on
the cabinet interconnect panel; the covers protect the
connectors from damage by static electricity or foreign
matter.
Do not make dc input power connections at the main dc
power source at this time.
The external converter supplying power to the cabinet
must have double or reinforced insulation between its
primary and secondary circuits.
The external converter that supplies power to the cabinet
must meet safety standard EN 60950.
An adequate means should be provided for routeing cables from the main
power source to the equipment, such as a cable trough or conduit.
NOTE The current-carrying capacity of a cable for continuous
service is affected by all of the following factors (reference
IEC 364):
– Ambient temperature.
– Grouping.
– Partial or total enclosure in thermal insulating material.
– Frequency (ac only).

Introduction to interoperability
Mixed product
sites
This chapter describes how the Horizon
macro
indoor can be used in conjunction
with other Motorola BTS products.
Different Motorola product types can be collocated at the same physical site
without restriction, provided they are configured as logically separate
installations, and in accordance with the normal product engineering rules.
When mixed product types are installed at the same logical
site
,
a number of
technical issues arise that restrict the hardware that can be configured, and the
way it is interfaced. This chapter explains which product types can be mixed in
this way, and how they are interfaced.
NOTE This chapter only applies to the Horizon
macro
GSM/
EGSM900 and DCS1800 BTS variants.
GSM850 and PCS1900 Horizon
macro
BTS variants
cannot be mixed with other Motorola BTS types.
Architectural
constraints
To enable different product types to be used at the same logical site, one
product type is chosen as master
,
which is connected to the extender equipment
so that the two product types can function as a single, logical BTS. This
approach is viable when the product types to be interfaced have similar
architectures.
Motorola BTS product types that can be interfaced for collocation at a single
logical site are therefore restricted to those shown in Table 3-1 below.

When two product types are interfaced in this way, the control function for the

. In practice, either BTS can be configured as master according to the
needs of the network concerned.

CONTROLLED INTRODUCTION
68P02902W08-B
Technical
issues
When mixing different BTS types, the interface may be required to resolve
some or all of the following issues, depending on the site configuration:
SThe interface must deliver both Rx and Rxdiv (receive diversity) signals to
each transceiver.
SThe interface must not change the uplink (receive) signal level delivered to
any transceiver.
SThe interface must ensure that in the mixed BTS configuration, RF
combiners remain correctly loaded.
Receive path
When a cell is wholly configured within one cabinet, there is no requirement to
connect the uplink or downlink RF signals between the master and extender
cabinets. The only interface between the cabinets in this type of mixed BTS
configuration is therefore at digital level, between FMUXs via the fibre optic link.
When a cell is split between two cabinets, the uplink signals must be connected
between the cabinets since both Rx and Rxdiv signals are required at each
transceiver. In this situation the downlink signal may or may not require
connection between cabinets, depending on the site configuration. The uplink
connectivity requirements are shown in Figure 3-4 (DCS1800) and Figure 3-5
(GSM900).

DCS1800
Refer to Figure 3-4. In the Horizon
macro
cabinet, low noise amplification in the
SURF module first boosts the Rx signal by +13 dB. Separate Rx outputs from
the SURF are then discretely routed to relevant transceivers in the master
cabinet, and to the LNA in the extender cabinet. Since the LNA boosts the Rx
signal by a further +13 dB, a 13 dB attenuator is placed in the signal path to
offset this additional signal gain, which would otherwise result in signal levels
outside the permitted range for the transceivers.
The Rxdiv signal is similarly given a +13 dB boost by the LNA in the extender
cabinet. Separate Rxdiv outputs from the LNA are then discretely routed to
relevant receivers in the extender cabinet, and to the SURF module in the
master cabinet. Since the SURF provides a further +13 dB boost, a 13 dB
attenuator is again placed in the signal path to offset this additional gain.
In this way, the arrangement shown in Figure 3-4 delivers Rx and Rxdiv signals
to the uplink path in both cabinets, at the required signal level.

Refer to Figure 3-5. In GSM900 products, RF gain for the IADU and SURF is
configurable. A split cell configuration is therefore dealt with in the same way as
that described for DCS1800, except that the 13 dB attennuators are not
required. Instead, the required signal level is maintained by using appropriate
gain settings for the IADU and SURF.

combining
When configuring the downlink paths for a cell using three carriers or more, it
may be necessary to provide additional external RF load(s) for the combiners.
This is illustrated by Figure 3-6, which shows a typical M-Cell

arrangement for a 4-carrier cell.

Carriers 1 and 2 are combined in a hybrid combiner (HCOMB) module. The
output from this module provides one of the three inputs to the 3IP CBF. The
HCOMB is equipped with an internal RF load, and is therefore self–contained.
The 3IP CBF requires one RF load for each of the two hybrids it contains, but is
equipped with only a single internal RF load. An additional load is therefore
provided for this purpose on the HCOMB casing.

When the two different product types are interfaced, a situation can arise where
a 3IP CBF is connected to an HCU, as shown in Figure 3-8. In this configuration
it is therefore necessary to provide an additional external RF load for this 3IP
CBF. The example in Figure 3-8 shows downlink connections for a 4/4/4
configuration using mixed BTS types.

are carriers 0 and 1, together with the combined output of HCOMB. 3IP CBF1
contains a single load and is therefore connected to the external load mounted
on HCOMB. Inputs for 3IP CBF2 are carriers 4 and 5, together with the output
of HCU1, from the master cabinet. 3IP CBF2 contains a single load and
therefore requires the addition of an external 50 ohm load, as shown.

Introduction to
decommission
procedures
This chapter describes how to decommission a Horizon
macro
indoor cabinet. To
decommission equipment not supplied by Motorola, for example E1/T1 links,
power supplies and antennas, refer to the vendor instructions.
WARNING Hazardous voltages in excess of 240 V ac may exist
inside a Horizon
macro
indoor cabinet.
Use extreme caution when working on a Horizon
macro
Indoor cabinet with power applied. Remove all rings,
watches and other jewellery.
In a stacked cabinet configuration, check that the bottom
cabinet is bolted to the floor using the supplied plinth. IF
NOT, this presents a danger of toppling that the
decommissioning personnel must take into account.
Before cabinet
decommission
Read all the earlier chapters of this installation section, before attempting to
decommission a Horizon
macro
indoor cabinet.
To
decommission
using checklist
The following procedure should be recorded by use of the checklist, to check
that each action has been completed. Photocopy the checklist as often as
required; do not write on the original manual copy.
Initial
decommission
checks
When starting to decommission a Horizon
macro
indoor cabinet:
SContact the OMC-R and ensure the cabinet is taken out of service.
SOpen the cabinet door and power down the cabinet, as described in
Powering down the cabinet in this section.

sufficient personnel are available to ensure that Health
and Safety regulations are not breached.
Eyebolts used to lift the cabinet must be of the collared
type, manufactured to CE conformity, and must have
sufficient safe working load to lift the cabinet, in
accordance with national or regional health and safety
regulations.
Motorola recommends the use of slings in conjunction with
hydraulic lifting apparatus for moving and positioning
Horizon
macro
cabinets.
The four screw locations used for hood pins must NOT be
used for eyebolts.
In addition to these points, refer to and comply with any
local regulations that govern the use of lifting equipment.
For the subsequent use of eyebolts, there may be local regulations that govern
the use of lifting equipment and stipulate a test and/or examination regime. If
the eyebolts are to be used, ensure that all such regulations are met.
Eyebolts can be fitted into the four designated cabinet top panel locations,
shown in Figure 5-1, after removal of the screws. These locations are identified
with an eyebolt symbol and the word LIFT. The eyebolt locations are also used
for stacking bracket attachment.

Removing
upper cabinet in
stacked
configuration
WARNING Check that the bottom cabinet is bolted to the floor using
the supplied plinth. IF NOT, this presents a danger of
toppling that the decommissioning personnel must take
into account.
To remove the upper cabinet in a stacked configuration:
1. If CCBs are fitted to upper cabinet, remove as described in Removing
CCBs in this section.
2. If stacking bracket is fitted to upper cabinet, remove as described in
Removing a stacking bracket in this section.
WARNING The cabinet can weigh up to 130 kg if fully equipped.
Handle each cabinet with extreme caution and in
accordance with local health and safety regulations.
Eyebolts are to be used with lifting equipment, and these
must be located in the correct position as shown in
Figure 5-1. The four screw locations used for hood pins
must NOT be used for eyebolts.
Before attempting to insert the eyebolts, visually check
each one for damage. If any damage is apparent, DO
NOT USE.
The eyebolts must not be over tightened; hand tight is
sufficient. Do not tighten eyebolts with a t-bar or
spanner. Screw the eyebolt fully into the lifting point so
that no thread is left exposed.
3. Fit eyebolts to the locations, identified with an eyebolt symbol and the
word LIFT. Attach eyebolts to suitable lifting equipment.
4. Remove the four bolts holding upper cabinet plinth to stacking bracket.
5. Lift upper cabinet, complete with plinth, off stacking bracket, and lower to
floor.
6. Remove the two M10 bolts securing plinth to cabinet, and slide apart.
7. Pack upper cabinet and plinth in separate containers, for storage,
transport or safe disposal.

A faulty master MCUF, FMUX or BPSM will cause a redundant module (if fitted)
to take over until the faulty module is replaced. Faulty MCUF, FMUX and BPSM
modules can be hot swapped without harm to the module or effect on normal
operation, provided the equivalent redundant module has taken over.
Removal of a faulty digital module that has not had its function taken over by a

Overview of
MCUF firmware
compatibility
In many installations a redundant MCUF is fitted and configured to assume
control in the event of a failure of the master MCUF. Under normal
circumstances, the redundant MCUF accepts code downloads from the master
MCUF and so remains updated and available for use.
If the redundant MCUF is replaced with a module containing firmware which is
incompatible with the master MCUF firmware, then the communicating link
between MCUFs will not be established. The redundant MCUF will therefore not
be updated and will not be available to take over when required.
Checking MCUF
firmware
compatibility
To check firmware compatibility between MCUFs, check the state of the base
transceiver processor (BTP) within each MCUF as follows:
1. Connect a PC to the TTY connection on the master MCUF.
2. At the CUST MMI prompt, enter:
state <site #> btp * *
Where <site #> is the site number.
The status of both BTPs will be displayed as follows:
BTP 0 0 0 B–U NO REASON
BTP 1 0 0 E–U NO REASON
or,
BTP 0 0 0 B–U NO REASON
BTP 1 0 0 D–U No Redundant Link
If No Redundant Link is indicated then the master MCUF is not in communication
with the redundant MCUF and firmware incompatibility may be assumed. Refer
to Updating redundant MCUF firmware.
Updating
redundant
MCUF firmware
The following procedure to update firmware in the redundant MCUF requires a
PCMCIA card containing current network configuration data. The procedure
assumes that the PCMCIA card is already in the master MCUF.
NOTE No call processing can take place during the MCUF
firmware update process. The entire process should take
approximately one hour.

Site preparation
To prepare for the firmware update the site must first be taken out-of-service as
follows:
1. Connect a PC to the TTY connection on the master MCUF.
2. At the CUST MMI prompt, disable all CTUs in turn by typing:
shutdown_device <site #> dri * * * <seconds>
Where <site #> is the site number, * * * is the DRI identifier and
<seconds> is the time delay before shutdown occurs.
3. Confirm this action by observing each CTU Tx status LED, which should
extinguish shortly after issuing the shutdown command.
4. Disconnect the 2.048 Mbit/s link
Redundant MCUF firmware update procedure
The following procedure describes how to update redundant MCUF firmware by
placing the redundant MCUF into the master position and downloading code
from a PCMCIA card.
1. Remove the uploaded PCMCIA card from the master MCUF, and ensure
that write protect is switched to OFF.
2. Remove both MCUFs. Insert the PCMCIA card into the original redundant
MCUF then insert this MCUF into the master position.
3. Connect a PC to the TTY connection on the MCUF front panel.
4. At the MMI-ROM prompt, type:
burn
This will flash object 8, the MCUF boot object, from the PCMCIA card onto
the MCUF card. The flash download takes approximately 30 seconds,
then the MCUF will reset.
5. At the MMI ROM prompt, type:
set_site <site #>
Where <site #> is the site number.
The MCUF now carries out a system initialization using data from the
PCMCIA card. After a short wait the screen displays:
Initialization complete. All commands accepted.
The MCUF firmware update is complete and both MCUFs now hold
identical firmware. The MCUF originally removed from the master position
may now be used in the redundant position.
6. Insert the original master MCUF into the redundant position.
The redundant MCUF now requires a 15 minute sync warm up period,
followed by a further delay of four minutes while the two MCUFs achieve
phase lock. Once phase lock is achieved the master MCUF immediately
begins codeloading to the redundant MCUF. Codeloading takes a further
15 minutes.
The process is complete when the following message is displayed on

Where <site #> is the site number, btp 0 0 0 is the master MCUF and btp
1 0 0 is the redundant MCUF.
This command will swap MCUF roles by forcing:
Sthe redundant MCUF into a busy state , and making it master.
Sthe master MCUF into an enabled state, and making it redundant.
4. At the CUST MMI prompt, confirm the swap by typing:
state <site #> btp * *
Where <site #> is the site number.
The status of both BTPs will now show changed roles:
BTP 0 0 0 E–U NO REASON
BTP 1 0 0 B–U NO REASON
5. Make test calls on the site to verify the new master MCUF.
6. At the CUST MMI prompt type, swap the MCUFs back to their original
states by typing:
swap_devices <site #> btp 1 0 0 btp 0 0 0
Where <site #> is the site number, btp 1 0 0 is the master MCUF and btp
0 0 0 is the redundant MCUF.
7. At the CUST MMI prompt, confirm the swap by typing:
state <site #> btp * *
Where <site #> is the site number.
Both BTPs have now reverted to their original roles:
BTP 0 0 0 B–U NO REASON
BTP 1 0 0 E–U NO REASON
8. Make test calls on the site to verify the new master MCUF.

Introduction to
Horizon
macro
indoor parts list
In the parts lists contained in this chapter, each item consists of a location
number (related to the associated diagram), description, and an order number.
The order number uniquely identifies the required component. Some
components are used in different equipment in addition to Horizon
macro
indoor.
Many items are the same for Horizon
macro
outdoor. Several items are the same
for M-Cell
6
.
FRU items
The majority of items on the parts list are field replaceable units (FRUs). It is not
intended to supply sub-units of these spares.
Ordering
method
Contact the local Motorola office for ordering information, including cost and
delivery.
If an item in the parts list is marked TBA, this means that the part number for the
item was not available at the time of publication of this manual.
NOTE Motorola reserves the right to change the design of the
product without notice. The information provided in this
chapter is intended as a guide. If the customer requires
the latest information, then consult the Motorola local
office who will be able to check on the web and confirm
the current situation.
Some items, for example CCBs and PSMs, are produced
by different manufacturers, and so a replacement may
appear slightly different to the item it is replacing. All items
bearing the same order number, regardless of
manufacturer, are fully compatible.
