Throughout this publication, all items referenced as“accessory items” are not furnished with the basic product and must be purchased separately.2 800 MHZ 20 WATT SYSTEM OVERVIEWThe Digivance 800 MHz 20 Watt System is an RF signal transport system that provides long-range RF coverage in areas where it is impractical to place aBase Transceiver Station (BTS) atthe antenna site. High real estate costs and community restrictions on tower and equipmentlocations often make it difficult to install the BTS at the same location as the antenna. TheDigivance system is designed to overcome equipment placement problems by allowing basestations to be hubbed at acentral location while placing remote antennas at optimum locationswith minimal real estate requirements. With the Digivance system, RF signals can betransported to one or more remote locations to expand coverage into areas not receiving serviceor to extend coverage into difficult to reach areas such as canyons, tunnels, or undergroundroadways.2.1 Basic System ComponentsThe basic components of aDigivance 20 Watt System and their functions are shown inFigure 1-1. A 20 Watt system consists of the Host Unit (HU) and the Remote Unit (RU). Bothan indoor and an outdoor remote unit are available. Control and monitoring functions areprovided by the Digivance Element Management System (DEMS), aPC-based softwareprogram. In addition, various accessory items are available separately including apassiveWavelength Division Multiplexer (WDM), an active Coarse Wavelength Division Multiplexer(CWDM) system, conditioning and duplexing panels (for interfacing the HU with the BTS),

The BTS/HU interface may require installation of the Digivance InterfacePanels which are accessory products for the Digivance system. The Interface Panels are usedwhen multiple BTS’s and multiple Host Units require connection or when RF attenuation isneeded between the BTS and Host Unit.Two types of Interface Panels are available: the Conditioning Panel and the Duplexing Panel. TheConditioning Panel provides attenuation of the forward path signal to the level required for inputto the Host Unit. The Conditioning Panel also provides forward and reverse path combining andsplitting (as needed) to enable multi-BTS to single Host Unit, multi-BTS to multi-Host Unit, orsingle BTS to multi-Host Unit configurations. Atypical single BTS to multi-Host Unitconfiguration is shown in Figure 1-2.Figure 1-2. BTS/HU Interface with Conditioning PanelThe Duplexing Panel is used in conjunction with the Conditioning Panel when the BTSprovides aduplexed forward and reverse path RF connection as shown in Figure 1-3.TheDuplexing Panel separates the duplexed forward and reverse path signals. This allows the BTSto be connected to the Host Unit which has separate forward and reverse path RF ports.18514-ARFRFRFRFBASETRANSCEIVERSTATIONCOAXIALCABLESCOAXIALCABLESHOST UNITHOST UNITHOST UNITCONDITIONINGPANEL

BTS/HU Interface With Conditioning Panel and Duplexing Panel2.3 Handset InterfaceThe RU interfaces with the handsets (cell phones) through an antenna. In the reverse path, theRU receives RF signals from each handset. The RU digitizes the RF signals and then convertsthem to digital optical signals for transport to the HU over the fiber optic link. In the forwardpath, the RU receives digital optical signals from the HU. The RU converts the optical signals toRF signals for transmission to the handsets. The RU is connected to an antenna (not provided)which transmits and receives the handset RF signals.2.4 Local Service InterfaceLocal communications with an individual Digivance system is supported through alocal serviceinterface capability as shown in Figure 4. The primary component of the local interface is aPC-type laptop computer loaded with the Digivance Element Management System (DEMS)software. DEMS provides the various control and monitoring functions required for localmanagement of each Digivance system. The DEMS computer can be directly connected toeither the HU or RU through the computer’s RS-232 port. Operation is effected through theDEMS Graphical User Interface (GUI). The GUI consists of aseries of screens from which theuser selects the desired option or function. An RS-232 service port is provided on both the HUand the RU for connecting the DEMS computer.18515-ARFRFRFRFRFBASETRANSCEIVERSTATIONCOAXIALCABLESCOAXIALCABLESHOST UNITHOST UNITHOST UNITCONDITIONINGPANELDUPLEXINGPANEL

Local Service Interface2.5 Remote NOC InterfaceRemote communications between aNetwork Operations Center (NOC) and anetworkedgrouping of multiple Digivance systems is supported by aremote NOC interface capability asshown in Figure 5. The primary component of the remote NOC interface is aPC-type desktopcomputer loaded with the Digivance Element Management System (DEMS) software. DEMSprovides the various control and monitoring functions required for remote management ofmultiple Digivance systems through aNOC.AController Area Network (CAN) port is provided on each HU so that up to twenty-four HU’scan be networked together in daisy-chain fashion and controlled though the same DEMScomputer. The DEMS computer connects to the networked HU’s through the computer’s RS-232 port #1. All HU’s can then be controlled through the same DEMS computer.The NOC is connected to the DEMS computer through adata network. The DEMS computer’sRS-232 port #2 interfaces with the data network equipment. The network equipment must becapable of interfacing with an RS-232 ASCII interface port.At the NOC, control and monitoring of the networked Digivance systems are effected through aNetwork Element Manager (NEM) interface which requires only aVT100 terminal/emulatorfor operation. The NEM interface language consists of simple ASCII text strings. Allcommunications are input as either SET or GET commands which result in ASCII text stringresponses from the specified system or systems. The DEMS desktop computer may also be usedlocally to manage the networked Digivance systems. Local operation is through the DEMSsoftware GUI.HOST UNITLAPTOP WITH DEMS(LOCAL INTERFACE)LAPTOP WITH DEMS(LOCAL INTERFACE)18524-ACD-ROM WITH DIGIVANCEELEMENT MANAGEMENTSYSTEM (DEMS) SOFTWAREREMOTEUNITRS-232RS-232

Because the opticalsignal is digital, the input and output RF signal levels at the HU or the RU are not dependent onthe level of the optical signal or the length of the optical fiber. Adiagram of the fiber optictransport system for atypical Digivance system is shown in Figure 1-6.The Digivance 20 Wattsystem does not support reverse path diversity.The maximum length of the optical fibers is dependent on the loss specifications of the opticalfiber and the losses imposed by the various connectors and splices. The system provides anoptical budget of 25 dB (typical) when used with 9/125 single-mode fiber.DESKTOP COMPUTER WITH DEMS(LOCAL AND REMOTE INTERFACE)HOST UNITHOST UNITHOST UNITNETWORKOPERATIONSCENTER(REMOTEINTERFACE)DATANETWORKCONTROLLERAREANETWORKCONTROLLERAREANETWORKRS-232 ASCIIRS-23218525-ACD-ROM WITH DIGVANCE ELEMENT MANAGEMENTSYSTEM (DEMS) SOFTWAREREMOTEUNITREMOTEUNITREMOTEUNIT

Standard Fiber Optic TransportIn some applications, it may be desirable or necessary to combine the forward path and reversepath optical signals onto asingle optical fiber. This can be accomplished by using apair ofpassive bi-directional Wavelength Division Multiplexers (WDM). The optical wavelengths usedin the system are 1550 nm for the forward path and 1310 nm for the reverse path. Becausedifferent wavelengths are used for the forward and reverse paths, both signals can be combinedon asingle optical fiber. One WDM is mounted with the HU and the other WDM is mountedwith the RU as shown in Figure 1-7.The WDMs are available as accessory items.Figure 1-7. Wavelength Division Multiplexer ApplicationIn some applications, it may be desirable or necessary to combine the forward and reverse pathoptical signals from multiple HU’s and RU’s onto asingle optical fiber. This can beaccomplished by using an active Coarse Wavelength Division Multiplexer (CWDM) system. Upto four 20 Watt systems may be configured to operate over asingle optical fiber. ACWDMmodule is mounted with each HU and RU as shown in Figure 1-8.The CWDM system convertsthe optical signal transmitted by each HU and RU to anew optical wavelength that is unique foreach unit. This allows the CWDM system to distinguish between the optical signals generatedby each HU and RU and therefore to distribute those signals to the appropriate destination. TheCWDM system is available separately as an accessory item.HOST UNIT18526-AREMOTEUNITFORWARD PATHREVERSE PATHFIBER OPTICLINKHOST UNIT18527-AREMOTEUNITFIBER OPTICLINKWDM WDMFORWARD ANDREVERSE PATH

The DEMS software is stored on aCD-ROM and shipped separately.Software installation consists of copying the software files from the CD-ROM to adesignateddirectory on the hard-drive of the DEMS computer.The DEMS software is used to provision and configure the Digivance system for operation.This includes selecting asitename, setting alarm thresholds, and setting forward and reversepath RF gain adjustments. The DEMS software is also used to get alarm messages (individual orsummary), data measurements, or to upgrade the HU/RU system software. All control andmonitor functions (except software upgrade which can only be done using the DEMS softwareGUI) can be effected using either the NOC/NEM interface or the DEMS software GUI.3.3 Fault Detection and Alarm ReportingLED indicators are provided on the front panel of the HU and on the front panels of the RUmodules to indicate if the system is normal or if afault is detected. In addition, normally openand normally closed alarm contacts (for both major and minor alarms) are provided at the HUfor connection to acustomer-provided external alarm system. All alarms can also be accessedthrough the NOC/NEM interface or the DEMS software GUI.3.4 PoweringThe HU is powered by ±24 or ±48 Vdc and must be hard-wired to alocal office battery powersource through afuse panel. Ascrew-down terminal strip is provided on the rear side of the HUfor the power connections.The RU is powered by 120 or 240 Vac (50 or 60 Hz) and must be hard-wired to an AC powersource through a20 Amp breaker box.

ADCP-75-150 • Preliminary Issue A • March 2003 • Section 2: DescriptionPage 2-3©2003, ADC Telecommunications, Inc.1 INTRODUCTIONThis section describes the basic components of the Digivance 800 MHz 20 Watt systemincluding the Host Unit (HU), the Remote Unit (RU), and the Digivance Element ManagementSystem (DEMS). The RU is an assembly that consists of acabinet (for outdoor applications) ormounting shelf (for indoor applications), aSpectrum Transport Module (STM), and aLinearPower Amplifier (LPA) module. For clarity, the various components that comprise the RU aredescribed separately.2 HOST UNITThe HU, shown in Figure 2-1,serves as the BTS servicing unit for the Digivance system. TheHU provides the following basic functions:• Provides an adjustable RF interface with the BTS.• Provides afiber optic interface with the RU.• Digitizes the forward path composite RF signal.•Convertsthe digitized forward path RF signal to adigital optical signal.•Convertsthe digitized reverse path optical signal to adigitized RF signal.•Convertsthe digitized reverse path RF signal to acomposite RF signal.• Signals alarm information to an external alarm system through relay contact closures• Provides an RS-232 interface for connecting the DEMS computer.• Provides aCAN interface for networking multiple HUs.2.1 Primary ComponentsThe HU consists of an electronic circuit board assembly and afan assembly that are mountedwithin apowder-paint coated sheet metal enclosure. The enclosure provides amounting pointfor the circuit board and fan assemblies and controls RF emissions. The only user-replaceablecomponent is the fan assembly. The HU is designed for use within anon-condensing indoorenvironment such as inside awiring closet or cabinet. All controls, connectors, and indicators(except the power terminal strip) are mounted on the HU front panel for convenient access.Cable management functions for the coaxial cables and copper wiring are provided by acablemanagement tray that extends outward from the HU front panel.2.2 MountingThe HU is intended for rack-mount applications. Apair of reversible mounting brackets isprovided that allow the HU to be mounted in either a19-inch or 23-inch EIA or WECOequipment rack. When installed, the front panel of the HU is flush with the front of the rack.The cable management tray extends 3.9 inches (99 mm) beyond the front panel. Fasteners areprovided for securing the HU to the equipment rack.
ADCP-75-150 • Preliminary Issue A • March 2003 • Section 2: DescriptionPage 2-4©2003, ADC Telecommunications, Inc.Figure 2-1. Host Unit2.3 Fault Detection and Alarm ReportingThe HU detects and reports various faults including host unit fault, optical fault, power fault,temperature fault, and RF fault. Various front panel Light Emitting Diode (LED) indicators turnfrom green to red or yellow if afault is detected. Aset of alarm contacts (normally open andnormally closed) are provided for reporting an alarm to an external alarm system when afault isdetected. Both major alarm (system operation seriously affected) and minor alarm (systemoperation not affected or only slightly degraded) contacts are provided.The status of the HU, the alarm state (major or minor), and other alarm information issummarized and reported over the service interface, the CAN interface, and also over the opticalfiber to the RU. In addition, the state of the RU is received over the optical fiber and reportedover the service interface and the CAN interface. This detailed information may be accessedremotely through the NOC/NEM interface or locally through the DEMS software GUI.2.4 RF Signal ConnectionsThe RF signal connections between the HU and the BTS are supported through two N-typefemale connectors. One connector is used for the forward path RF signal. The other connector isused for the reverse path RF signal. The 20 Watt system does not support adiversity reversepath. In most installations, it is usually necessary to install aConditioning Panel and/orDuplexing Panel (accessory items) to support the interface between the HU and the BTS. TheHU should be as close as possible to the BTS to minimize cable losses.2.5 RF Signal Level AdjustmentsThe HU is equipped with several attenuators for adjusting the signal levels of the forward andreverse path RF signals. The attenuators provide an attenuation adjustment range of 0to 31 dBand can be set in 1dB increments. The attenuators are software controlled and are adjustedthrough the NOC/NEM interface or the DEMS software GUI.17.2 INCHES(437 mm)3.5 INCHES(89 mm)11.4 INCHES(290 mm)15.3 INCHES(389 mm)FRONT PANELCABLE MANAGEMENTTRAYMOUNTINGBRACKET(BOTH SIDES)18531-A
ADCP-75-150 • Preliminary Issue A • March 2003 • Section 2: DescriptionPage 2-5©2003, ADC Telecommunications, Inc.The host forward path attenuator adjusts the level of the input RF signal to the HU. Using theforward path attenuator, an input signal with anominal composite signal level of –10 dBm to–40 dBm can be adjusted to produce maximum power output. Additional external attenuationis required if the input signal level is greater than –10 dBm.The host reverse path attenuator adjusts the level of the output RF signal and will add from –1dB of attenuation (attenuator set to 31 dB) to 30 dB of gain (attenuator set to 0dB) to the outputsignal at the HU.2.6 Propagation DelayThe HU forward, reverse, and diversity reverse path propagation delays may be adjusted in 0.1µsec increments within arange of 0–63 µs. The propagation delay is software controlled andmay be adjusted through the NOC/NEM interface or the DEMS software GUI.2.7 Optical ConnectionOptical connections between the HU and the RU (STM) are supported through two SC-typeoptical connector ports. One port is used for connecting the forward path optical signal and theother port is used for connecting the primary reverse path optical signal.2.8 Controller Area Network Interface ConnectionController Area Network (CAN) interface connections between multiple HUs are supported byapair of RJ-45 jacks. One of the jacks is designated as the network IN port and the other jack isdesignated as the network OUT port. The CAN interface allows up to 24 HUs to be connectedtogether (in daisy-chain fashion) and controlled through asingle Digivance DEMS computer.2.9 Service Interface ConnectionThe service interface connection between the HU and the Digivance DEMS computer issupported by asingle DB-9 female connector. The service connector provides an RS-232 DTEinterface. When multiple HUs are networked together, the supporting DEMS computer may beconnected to the service connector of any one of the networked HUs.2.10 PoweringThe HU is powered by ±24 or ±48 Vdc power. The power is fed to the HU through ascrew-down type terminal strip located on the rear side of the unit. Power to the HU must be suppliedthrough afuse panel such as the 20 position PowerWorx fuse panel (available separately). Thepower circuit for each HU must be protected with a 3 Amp GMT fuse. An On/Off switch isprovided on the HU front panel.
