1. Overview MainStreet Broadband Wireless Technical PracticesIssue 1, April 1999 NNP 95-4882-01-00-A1-2 DRAFTTable 1-1 describes major components of a broadband wireless system.Table 1-1: Components of the wireless systemMost of the air interface configuration is performed through the T-ARIC card; configuration of the NIUs is primarily related to TDM functionality. ATM functionality is provided by other cards in the MainStreetXpress 36170 shelf.Table 1-2 describes the network management support available for the MainStreet Broadband Wireless system.Table 1-2: MainStreet Broadband Wireless network managementTerm DescriptionATM backbone The ATM backbone system is used for switching intercell traffic and connecting multiple BTSs.BTS The Base Transceiver Station is the linking point between customers in the coverage area of the BTS and the backbone network. The BTS is a hub that collects and delivers all traffic to and from subscribers within the coverage area.Cell The cell is the geographical area that is within range of the transmit and receive antennas at the BTS.NIU The Network Interface Unit provides the linking point between the customer equipment and the air interface at the customer site. The MainStreet Broadband Wireless system includes the 28110 and 28120 MainStreet CE Plus Ethernet NIUs.OTU The OTU is the transmit radio for the BTS. ORU The ORU is the receive radio for the BTS. Sector A sector is the smallest geographical area which has access to the entire Tx and Rx RF spectrum used in a wireless system. A sector can be a division of a cell, or an entire cell. A cell is often divided into sectors to simplify network and node management, and to take advantage of antenna profiles. T-ARIC card The Time Division Multiple Access - ATM Radio Interface Card resides in a MainStreetXpress 36170 shelf, and provides a cell relay modem interface between the BTS and one or more NIUs.T-ARIC group A T-ARIC group is two or more T-ARIC cards configured to use the same OTU/ORU. This allows for an increase in CPE density within the cell.OTRU An OTRU is a transceiver installed at a CPE site that connects to an NIU, providing RF connectivity between the NIU and the OTU/ORU. Term DescriptionMainStreetXpress 45020 The MainStreetXpress 45020 Element Manager provides remote SNMP management of the NIUs.MainStreetXpress 46020 The MainStreetXpress 46020 Network Manager provides remote management of the T-ARIC cards.NMTI The NMTI is a user interface for local management of the T-ARICs and NIUs. Remote access is configured through the PSTN.

MainStreet Broadband Wireless Technical Practices 1. OverviewNNP 95-4882-01-00-A Issue 1, April 1999 1-3DRAFT1.2 Frequency and bandwidth utilizationFigure 1-2 shows the signal flow between the T-ARIC card located at the BTS and an NIU located at a CPE site. The signals between the T-ARIC card and the OTU/ORU use IF. Signals between the OTU, ORU and the OTRU transceiver use RF. Signals between the OTRU transceiver and the NIU also use IF.Figure 1-2: Signal flowThe term downstream always refers to the communication flow from the T-ARIC card to the NIU. Upstream always refers to communication flow from the NIU to the T-ARIC card.The MainStreet Broadband Wireless system supports wireless communications in the 20 to 40 GHz frequency range. The actual frequencies used are country-dependent.Bandwidth between the T-ARIC card and the OTU and ORU is in the IF range. The range is 400 to 900 MHz upstream, and 950 to 2050 MHz downstream. Bandwidth between the NIU and the transceiver is also in the IF range. The relationship between IF and RF frequencies is determined by the specific radios that are used in the OTU and ORU and the transceiver.Figure 1-3 shows details of data flow on an upstream and a downstream channel. The downstream channel is broadcast to all NIUs configured to be in the same T-ARIC group as the broadcasting T-ARIC card.The MainStreet Broadband Wireless system uses TDMA to allow multiple NIUs to use a single upstream channel. In Figure 1-3, two NIUs are broadcasting on a single channel. The channel is divided into timeslots. These timeslots are allocated to the NIUs by system resources, not by manual configuration. The number of timeslots allocated to an NIU depends on the configured TDM traffic.T-ARICATM network(throughMainStreetXpress36170)BTS CPEOTUORUTxRxDownstream DownstreamUpstream UpstreamUpstreamDownstreamRFOTRUIFNIU11437

Installing the base transceiver station componentsThis chapter describes how to install the base transceiver station components.3.1 BTS installation overviewBTS components and cables should be installed by qualified RF equipment installers.SitingThe MainStreet Broadband Wireless requires line -of-sight access between BTS OTU/ORU equipment and CPE OTRUs. Each installation must be planned by qualified RF engineers to optimize cell placement and minimize line-of-sight BTS to CPE blockage by doing appropriate RF site planning, and using appropriate equipment and procedures.Customer-supplied equipmentCustomers installing a BTS will need to supply: •attenuators•coaxial cable that runs from the 12:2 Combiner/Splitters to the outdoor radios•RS-422 cable that runs from the MAU to the OTU and ORU•a grounded entry point•ground wires and connectors•weatherproof cable entry panel(s)•poles or towers for ORU, OTU and OTRU mounting•miscellaneous supplies (such as butyl electrical tape, cable cutter, wire stripper and crimping tool)Broadband cablesBecause many factors are associated with choosing a suitable coaxial cable, customers will be advised by Newbridge of the manufacturers and manufacturer part numbers recommended for each cable assembly.

3. Installing the base transceiver station components MainStreet Broadband Wireless Technical PracticesIssue 1, April 1999 NNP 95-4882-01-00-A3-2 DRAFTThe cable path from the T-ARIC card to the OTU or ORU must provide a fixed common loss. The losses are:•downstream: 27 ±1 dB at 2050 MHz•upstream: 24 ±1 dB at 900 MHzIf the total loss falls short of these values, attenuators must be installed. Grounded entry pointEach BTS requires a grounded entry point in order to ground BTS components and cables. Refer to local electrical code requirements when choosing a grounded entry point for the BTS.OTU and ORU radiosThe OTU and ORU radios are designed to be installed on antenna tower(s), masts, buildings or other appropriate fixtures. The MainStreet Broadband Wireless system supports both simplex and redundant OTU and ORU configurations.The distance between the T-ARIC card and the outdoor transmitter and receiver can be over 200 m (656 ft) with the use of high-quality, low-loss coaxial cable. This allows the RF equipment to be located on a tower or on a building while the T-ARIC card and MainStreetXpress 36170 shelves are installed indoors. 3.2 Installing BTS componentsFigure 3-1 shows a diagram of a typical simplex BTS configuration. Figure 3-2 shows a diagram of a redundant BTS configuration. Grounding, surge protection and power connection are similar to the simplex system. Table 3-1 lists the BTS components and part numbers.

BTS cable connectionsNNP 95-4882-01-00-A Issue 1, April 1999 9-3DRAFTTable 9-2: BTS cable connectors9.2 Connecting BTS broadband cablesNoteOutdoor BTS broadband cables should be grounded via the outer conductor every 15 m (50 ft). BTS cables, connectors and equipment must provide a fixed decibel loss in both the upstream and downstream directions. The downstream losses must total 27 dB at 2050 MHz, ± 1 dB. The upstream losses must total 24 dB at 900 MHz, ± 1 dB. If the total loss is less than the required value, attenuators are installed between SMA cables and the 12:2 Combiner/Splitters.In order to maintain a fixed cable loss, different cable types are selected depending on the distance between the T-ARIC card and the OTU and ORU.Table 9-3 shows the recommended cable types for specific distances. Tables 9-4 through 9-9 show how the fixed loss is calculated for each type of cable.OTU RS-422 connector to T-ARIC MAU Tx connectorOTU to RS-422 lightning arresterRS-422 lightning arrester to MAU OTU connectorLEMO - RJ45 RJ45 - RJ45 Delco 398087PORU RS-422 connector to T-ARIC MAU Rx connectorORU to RS-422 lightning arresterRS-422 lightning arrester to MAU ORU connectorLEMO - RJ45 RJ45 - RJ45 Delco 398087PORU to OTU 100 MHz reference cable N(M) - N(M) LDF4-50ACR-50-540 PEBias-T power cable n/a BNC(M) - lug connectors 90-6516-01Physical path Intermediate cables Connectors Recommended cable specificationConnector Part numberN(M) 90-6657-01 (1 connector)90-6657-02 (25 connectors)LEMO 90-6816-01RJ-45 90-6815-01

Installing the customer premises equipment MainStreet Broadband Wireless Technical PracticesIssue 1, April 1999 NNP 95-4882-01-00-A10-2 DRAFTCable lossThe CPE passive components, in all installations, are designed to provide a fixed common loss. The losses are:•downstream: maximum 16 dB at 2050 MHz•upstream: 8 ±1 dB at 700 MHzIf the total loss of the installed passive components falls short of these values, do not insert attenuators to make up the difference. Use a specific cable length to make up the loss. Passive componentsPassive components for the CPE consist of a single coaxial cable from the NIU to the OTRU. Figure 10-2 shows a typical single NIU and dual NIU passive component configuration. Power for the radio is duplexed onto the line by the NIU; hence, no external power supply is required. Properly grounded lightning arresters are highly recommended at the building entry point. Every customer site is different. Therefore, cable runs on the inside and outside of the premises will vary from site to site. As with the BTS, Newbridge can recommend the cable type and specifications for customers wishing to optimize their CPE sites by running their own cable. Because there are many factors associated with choosing a suitable coaxial cable, customers will be advised by Newbridge of the manufacturers and manufacturers part numbers recommended for these cable assemblies.To interconnect two NIUs to one CPE OTRU, a 2:1 Combiner/Splitter is required.

2. Ensure that the BTS is transmitting a signal in the CPE sector.3. Adjust the bolts identified in Figure 14-1 until the OTRU mounting hardware is sufficiently snug to hold the unit on the mast, but is loose enough to allow easy rotation of the unit by hand. Set the azimuth, elevation and rotation of the antenna to point at the approximate location of the BTS.4. Switch the NIU on.5. Prepare the test equipment to make the measurements.a. If measurements are made using a power meter, set AVERAGING to a low figure (for example, 2).b. If a spectrum analyzer is used, set CENTER FREQUENCY to a value that is 200 MHz higher than the tone frequency at the BTS, and set BANDWIDTH to 100 MHz.6. Observe and record the measurement on the test equipment, and adjust the azimuth of the OTRU to provide a peak power reading.7. Observe and record the measurement on the test equipment, and adjust the elevation of the OTRU to provide a peak reading.8. Observe and record the measurement on the test equipment, and adjust the vertical angle of the OTRU to provide a peak reading.9. Tighten the mounting hardware and verify the measurements previously made to ensure that the OTRU is still aligned to provide a peak reading on the test equipment.10. Switch the NIU off, disconnect the test equipment and reconnect the outdoor cable to the OTRU. Switch the NIU on.

Node managementThis chapter describes:•node management through the NMTI•the main menu15.1 Node management overviewNMTI user interfaceThe NMTI is a user-interface software program that resides in the PROM module on the NIUs and the MainStreetXpress 36170 Control card. It allows you to have a node management session through an attached ASCII (VT100-compatible) terminal. The 28110 and 28120 MainStreet NIUs have their own NMTIs, which are used to set up, operate, monitor and maintain the NIUs.Although the T-ARIC card does not have its own NMTI, it can be configured through an NMTI session with the MainStreetXpress 36170 Control card. For information on initiating a node management session with the MainStreetXpress 36170 Control card, see the MainStreetXpress 36170 Technical Practices. For information on softkey conventions used in this manual, see “Softkeys” in section 15.2.To initiate a node management session with an NIUThe following steps describe the logon procedure for the first NMTI session. Users logging on later may find that some steps are not necessary, are slightly different or are skipped because previous users have changed the configuration. If the node management equipment is used regularly, steps 1 to 3 may not be necessary.1. Switch on the NIU. The power switch is on the back panel.The LED display runs through a predetermined pattern, while self-diagnostics are performed.2. Ensure the terminal is connected to the front panel serial port of the NIU and switch on the terminal.

NIU TDM configuration optionsThis chapter describes how to configure the TDM options. The options supported by the 28110 and 28120 MainStreet NIUs include:•channel groups•ports•robbed bit signaling (forthe 28110 MainStreet T1 NIU only)•serial ports•trunk conditioning18.1 Channel group configurationChannel group configuration includes:•adding channels to a channel group•assigning the channel group name•deleting channels from a channel groupNoteChannel groups can only be configured if the NIU port has an AAL service type of SDT_BASIC or SDT_CAS. Restrictions on channel group configurationThe following restrictions apply.•A channel can belong to only one channel group at a time.•A channel group must be identified by the lowest number channel that is a part of the group. For example, CG3 must contain channel 3 and not channel 1 or channel 2.•Channel 31 corresponds to timeslot 16 on an E1 port; if you configure channel 31 as part of a channel group, the system treats channel 31 as though it is timeslot 16. For example, a channel group containing channels 16, 20 and 31 is identified as CG31 because the timeslot that corresponds to channel 31 (timeslot 16) comes before the timeslot that corresponds to channel 16 (timeslot 17) on an E1 port.

The NIU ATM configuration options are:•AAL service type•padding octet value•playout buffer•user data octets per cell The only T-ARIC card ATM configuration option is NIU user data VPI.19.1 NIU ATM configuration optionsAAL service typeEach port is configured to provide either structured or unstructured data transfer.When a structured data mode is selected (SDT_BASIC and SDT_CAS), framing is passed or inserted. SDT_CAS mode passes signaling bits on each of the contained channel groups, while SDT_BASIC removes signaling bits.When an unstructured data mode is selected (UDT and UDT_PERFMON), framing is not passed or inserted. UDT_PERFMON allows performance monitoring statistics to be collected from the port. UDT mode blocks the collection of performance monitoring statistics.CautionSelection of any of the UDT or SDT keys removes all configured channel groups and connections on the port. Note 1 CAS cannot be selected on E1 ports that are configured for 31-channel framing.Note 2 RBS and zero suppression options are available only for SDT_BASIC, SDT_CAS and UDT_PERFMON mode.

Air interface configurationNNP 95-4882-01-00-A Issue 1, April 1999 21-3DRAFT21.2 Frequency offsetsThis section describes the functions of:•downstream frequency offset for the NIUs•Rx LO offset for the T-ARIC cardDownstream frequency offsetThere is a fixed RF range for which the transceiver radio can receive signals over the air. Likewise, there is a fixed IF range for which the transceiver radio can transmit to the NIU modem. Radios that are supplied by different manufacturers do not necessarily support the same IF range, even though the radios support the same RF range.The downstream frequency offset provides a method of compensating for differences between the modem and transceiver IF spectrums. The value configured as the downstream frequency offset is the difference between the modem IF range and the transceiver IF range.For Release 1.1, keep the downstream frequency offset at the default value (0).Rx LO offsetThere is a fixed RF range for which the BTS Rx radio can receive signals over the air. Likewise, there is a fixed IF range for which the BTS OTU can transmit to the T-ARIC modem. Ideally, the IF spectrum should be the same for the OTU, ORU and modem.The Rx LO offset compensates for differences between the modem and the Rx radio IF spectrums. The value configured as the Rx LO offset is the difference between the modem IF range and the ORU IF range.For Release 1.1, keep the Rx LO offset at the default value (150).

Air interface configuration MainStreet Broadband Wireless Technical PracticesIssue 1, April 1999 NNP 95-4882-01-00-A21-6 DRAFTChannel bandwidth, frequency and number of channelsEach T-ARIC card in the T-ARIC group transmits downstream on a different frequency range, called the downstream RF channel (see 3 and 4 in Figure 21-1). An RF channel is defined by the channel frequency and the channel bandwidth. You must configure each NIU to receive in the appropriate RF channel. The add frequency feature allows you to create a list of channels; the NIU attempts to connect to each channel in turn until a connection is established.When you add a channel to a list of channels, specify the channel frequency and the channel bandwidth. The channel frequency, or the center of the RF channel, is fixed at 18 MHz.You can create multiple RF channels simultaneously by specifying the lowest center RF, the channel bandwidth and the number of channels you want to create. The channels run consecutively.The system assigns a unique channel identifier in the range 1 to 30 for each channel.Downstream channel frequency and bandwidthEach T-ARIC card in a T-ARIC group transmits downstream on a different frequency range, called the downstream RF channel. An RF channel is defined by the channel frequency and the channel bandwidth. You must specify a channel bandwidth and a channel frequency for each T-ARIC card in a T-ARIC group (see 3 and 4 in Figure 21-1). The channels cannot overlap.The channel frequency, or the center of the RF channel, is fixed at 18 MHz. Although it is not strictly necessary, it is good practice to configure all RF channels to use contiguous bandwidth.Downstream IF start frequencyCommunication between a Modem module located on a T-ARIC card and an ORU or OTU are in the IF spectrum. Each T-ARIC card in a T-ARIC group uses a different downstream IF frequency range. You must specify the start (that is, the lowest) downstream IF frequency. The other IF ranges are determined by the T-ARIC card and are not user-configurable.Rx upstream frequency start and endEach T-ARIC card in the T-ARIC group receives upstream on a different frequency range, called the upstream RF channel. An RF channel is defined by the channel frequency and the channel bandwidth. At the T-ARIC group level, you must configure the upstream RF start and end frequency (see 7 and 8 in Figure 21-1). The upstream RF frequency start is the lower limit of the lowest upstream RF channel. The upstream RF frequency end is the higher limit of the highest RF upstream channel.

Air interface configurationNNP 95-4882-01-00-A Issue 1, April 1999 21-7DRAFTTx downstream frequency start and endEach T-ARIC card in a T-ARIC group transmits downstream on a different frequency range, called the downstream RF channel. An RF channel is defined by the channel frequency and the channel bandwidth. At a T-ARIC group level, you must configure the downstream RF start frequency and end frequency (see 1 and 2 in Figure 21-1).The downstream RF frequency start is the lower limit of the lowest downstream RF channel. The downstream RF frequency end is the higher limit of the highest RF downstream channel.Upstream channel frequencyEach T-ARIC card in a T-ARIC group receives upstream on a different frequency range, called the upstream RF channel. An RF channel is defined by the channel frequency and the channel bandwidth. The upstream channel width is fixed at9 MHz. You must specify a channel frequency for each T-ARIC card in a T-ARIC group (see 9 and 10 in Figure 21-1). The channels cannot overlap. The channel frequency is the center of the RF channel; the channel width is 9 MHz. For example, if you specify a channel frequency of 27 355 MHz, the channel itself begins at 27 350.5 MHz and ends at 27 359.5 MHz. Although a T-ARIC card receives on two separate RF channels, specify the channel frequency for one channel only. If you configure the upstream channel frequency for upstream 1, then the channel frequency for upstream 2 is automatically set to the channel frequency for upstream 1 plus 9 MHz. If you configure the upstream channel frequency for upstream 2, then the channel frequency for upstream 1 is automatically set to the channel frequency for upstream 2 minus 9 MHz.Although it is not strictly necessary, it is good practice to configure all RF channels to use contiguous bandwidth.Upstream IF start frequencyCommunications between a Modem module located on a T-ARIC card and an OTU/ORU are in the IF spectrum. Each T-ARIC card in a T-ARIC group uses a different upstream IF frequency range. You must configure the start (that is, the lowest) upstream IF frequency. The other IF ranges are determined by a T-ARIC card and are not user-configurable.Upstream frequency offsetThe T-ARIC card must know the beginning of the NIU Tx IF band in order to communicate with the NIU. The upstream frequency offset is used by the BTS to calculate the NIU Tx IF band. The frequency offset is defined as the CPE IF start frequency minus the BTS IF start frequency. Therefore, if the BTS IF start frequency is 400 MHz, and the CPE IF start frequency is 550 MHz, configure the upstream frequency offset as -150 MHz. This will allow the BTS to communicate with the NIU on the appropriate IF frequency.

Air interface configuration MainStreet Broadband Wireless Technical PracticesIssue 1, April 1999 NNP 95-4882-01-00-A21-8 DRAFT21.4 GroupsYou can connect up to 12 T-ARIC cards and configure them to use the same OTU/ORU. Some configurable parameters can be common to each of the T-ARIC cards in the group.Note that even single T-ARIC cards must belong to a group; in this case, the group has only one T-ARIC card.21.5 NIUThe following parameters are configurable on a T-ARIC card:•add NIU•NIU ID•NIU serial number•NIU typeAdd NIUBefore the system can establish any communication over the air interface, you must configure each T-ARIC card with the NIU ID of each NIU that a T-ARIC card is to communicate with. This procedure consists of adding each NIU to one of the two demodulators on a T-ARIC card.NIU ID and NIU serial numberEach NIU is physically configured at the time of manufacture with a unique NIU serial number of up to 19 characters. You must configure the NIU with an NIU ID in the range 100 to 3299. The NIU ID must be unique within a BTS, but the same NIU ID can be used in more than one BTS.During configuration of the T-ARIC card, you must associate each NIU with one of the two T-ARIC card upstreams, by programming the T-ARIC card upstream with the NIU ID.NIU typeThe MainStreet Broadband Wireless system supports only CE NIUs.

The process of entering the network is called network registration.Figure 21-2 shows relative values for the minimum and maximum NIU transmit values before and after network entry.Figure 21-2: NIU power levels before and after network entryThe minimum and maximum transmit power levels used before network entry are a subset of the transmit values that are used after network entry. The BTS is able to receive from the NIU at the minimum transmit power level in normal operating conditions. If the BTS does not respond, the NIU increases the transmit power until the maximum transmit power level is reached.The purpose of configuring a maximum power level before network entry is to prevent the NIU from interfering with other equipment. If an NIU transceiver is not aligned with a BTS, and if there were no maximum transmit limit, the NIU would continue to increase the transmit power and ultimately cause interference with other network equipment.After the NIU has registered with the network, the NIU adjusts the transmit power level in response to the power level received from the BTS. If the receive power level increases, the NIU lowers the transmit power level; if the receive power level decreases, the NIU increases the transmit power level.Transmit power level0Before networkentry After networkentryMaximumMaximumMinimum Minimum11440

21. Air interface configuration MainStreet Broadband Wireless Technical PracticesIssue 1, April 1999 NNP 95-4882-01-00-A21-10 DRAFTYou should configure the minimum power level used after network entry at a level that the BTS can always receive.The minimum power level used after network entry ensures that the NIU cannot reduce the transmit power level to a level that cannot be received by the BTS. The maximum power level used after network entry ensures that the NIU does not increase the transmit power level to a level that interferes with other network equipment.The maximum power level used after network entry can be set higher than the maximum power level used before network entry, because until the NIU has registered you cannot be certain that the NIU and the BTS are aligned. The overall intent of providing configurable transmit levels for each NIU is to try to ensure that the receive power at the BTS is consistent. NIUs that are close to the BTS have lower transmit power levels than NIUs that are farther away.21.7 Rx and Tx redundancyThis section describes the functions of:•Rx control•Tx controlThe MainStreet Broadband wireless system supports redundancy only for the OTUs and ORUs. Rx and Tx redundancy is supported at the T-ARIC group level; you can configure each T-ARIC card in the T-ARIC group to control one receiver and/or one transmitter.Figure 21-3 shows a T-ARIC group with two T-ARIC cards. T-ARIC 1 is connected to an OTU and an ORU. T-ARIC 2 is connected to an OTU, but not to an ORU. If the active transmitter connected to T-ARIC 1 fails, the inactive transmitter connected to T-ARIC 2 becomes active.

Figure 21-4 shows an example of timeslot utilization on an upstream channel.Figure 21-4: Timeslot utilization on an upstream channelContention timeslotsThe E1 and T1 NIUs use contention timeslots to communicate with the T-ARIC card. These timeslots do not carry user data. You configure the number of contention timeslots independently for each of the two upstream demodulators on the T-ARIC card.All NIUs connected to the upstream demodulator share access to the contention timeslots, but a contention timeslot can only be used by a single NIU at a time. If no contention timeslots are available and the NIU needs to communicate with the T-ARIC card, the NIU must make successive attempts until a contention timeslot becomes available.At least one timeslot must be reserved for contention. The T-ARIC card determines the location of the contention timeslots within the upstream channel.1143901... ... ... ... ...15 47 98 102 132Polling timeslotsTimeslot 0 alwaysreserved forpollingLocation ofadditional pollingslots handled byT-ARICUBR reserved timeslotlocation handledby T-ARICGuard timeslots1 to 3 guard timeslotsimmediately followtimeslot 0Contention timeslotlocation handled by T-ARICAll non-allocated timeslotscan be used by E1 + T1 NIUS

MainStreet Broadband Wireless Technical Practices 21. Air interface configurationNNP 95-4882-01-00-A Issue 1, April 1999 21-13DRAFTGuard and polling timeslotsDuring the process of network entry, the NIU attempts to communicate with the T-ARIC card on an assigned polling slot. Timeslot 0 is called a polling timeslot. Because the NIUs may not be synchronized with the BTS during the network entry process, it is possible that the message from the NIU might overflow into the next timeslot. Guard slots are timeslots that do not carry user data. Guard slots immediately follow the polling slot and guarantee that timeslots used for user data are not interfered with by NIUs attempting to enter the network. At least one timeslot must be reserved as a guard timeslot, which is why polling timeslots used for network entry are followed by guard timeslots.The T-ARIC card continues to poll the NIUs after the NIUs have entered the network. To prevent congestion on timeslot 0 you can configure additional polling slots. These polling slots are used only by NIUs that have entered the network, so guard timeslots are not needed. The T-ARIC card determines the location of any additional polling timeslots. You only configure the number of polling timeslots.Reserved DBA timeslotsYou configure the number of timeslots that are available for use for bandwidth-on-demand by NIUs. These timeslots are used for the Ethernet port, MAC messages and management data.If no DBA timeslots are reserved, NIU CBR connections might use all available bandwidth. All NIU connections are CBR.The T-ARIC card determines the location of the reserved DBA timeslots. You only configure the number of reserved DBA timeslots.
