Throughout thispublication, all items referenced as “accessory items” are not furnished with the basic productand must be purchased separately.2 SINGLE BAND SYSTEM OVERVIEWThe Digivance single band 1900 MHz LRCS is an RF signal transport system that provideslong-range RF coverage in areas where it is impractical to place aBase Transceiver Station(BTS) at the antenna site. High real estate costs and community restrictions on tower andequipment locations often make it difficult to install the BTS at the same location as theantenna. The Digivance LRCS is designed to overcome equipment placement problems byallowing base stations to be hubbed at acentral location while placing remote antennas atoptimum locations with minimal real estate requirements. With the Digivance LRCS, RFsignals can be transported to one or more remote locations to expand coverage into areas notreceiving service or to extend coverage into difficult to reach areas such as canyons, tunnels, orunderground roadways.2.1 Basic ComponentsThe basic components of asingle band Digivance LRCS system and their functions are shownin Figure 1-1. A single band LRCS system consists of aHost Unit (HU) and aRemote Unit(RU). Control and monitoring functions are provided by the Digivance Element ManagementSystem (EMS). On an optional basis, each HU and RU system may be ordered either with orwithout reverse path diversity. In addition, various accessory items including aback-up batterykit (for the RU), aWave Division Multiplexer (WDM) module (for the HU and RU), networkcables (for connecting multiple HU’s together), and EMS cable (for connecting the EMScomputer to the HU) are available separately.

System Overview Diagram2.2 Base Transceiver Station InterfaceThe HU is co-located with the BTS and interfaces directly with the BTS over coaxial cables. Inthe forward path, the HU receives RF signals from the BTS. The HU digitizes the RF signalsand then converts them to digital optical signals for transport to the RU. In the reverse path, theHU receives digital optical signals from the RU. The HU converts the digital optical signalsback to RF signals for transmission to the BTS.EBTSEBTSEBTSDIGIVANCE ELEMENTMANAGEMENT SYSTEMRFRFRFHOST UNITHOST UNITHOST UNITREMOTE UNITREMOTE UNITREMOTE UNITNETWORKOPERATIONSCENTER(REMOTE INTERFACE)LAPTOP(LOCAL INTERFACE)DATANETWORKCONTROLLER AREANETWORKRS-232 ASCIIRS-232RS-23216969-BCD-ROM WITH EMSSOFTWARE
ADCP-75-126 • Issue B • April 2002 • Section 1: OverviewPage 1-3©2002, ADC Telecommunications, Inc.2.3 Handset InterfaceThe RU interfaces with the handsets through an antenna. In the reverse path, the RU receives RFsignals from each handset. The RU digitizes the RF signals and then converts them to digitaloptical signals for transport to the HU. In the forward path, the RU receives digital opticalsignals from the HU. The RU converts the optical signals to RF signals for transmission to thehandsets. The RU is connected to an antenna which transmits and receives the handset RFsignals.2.4 Local Service InterfaceLocal communications with an individual Digivance LRCS system is supported through alocalservice interface capability. The primary component of the local interface is aPC-type laptopcomputer loaded with the Digivance Element Management System (EMS) software. The EMSprovides the various control and monitoring functions required for local management of eachLRSC system. The EMS computer can be directly connected to either the HU or RU through thecomputer’s RS-232 port. Operation is effected through the EMS Graphical User Interface(GUI). The GUI consists of aseries of screens from which the user selects the desired option orfunction. An RS-232 service port is provided on both the HU and the RU for connecting theEMS computer.2.5 Remote NOC InterfaceRemote communications between aNetwork Operations Center (NOC) and anetworkedgrouping of multiple Digivance LRCS systems is supported by aremote NOC interfacecapability. The primary component of the remote NOC interface is aPC-type desktop computerloaded with the Digivance Element Management System (EMS) software. In addition to the localmanagement functions described in the previous section, the EMS also provides the variouscontrol and monitoring functions required for remote management of multiple LRSC systemsthrough 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 EMScomputer. The EMS computer connects to the networked HU’s through the computer’s RS-232port #1. All HU’s can then be controlled through the same EMS computer.The NOC is connected to the EMS computer through adata network or dial-up modem. TheEMS computer’s RS-232 port #2 interfaces with the data network equipment. The network ordial-up modem equipment must be capable of interfacing with an RS-232 ASCII interface port.At the NOC, control and monitoring of the networked LRCS 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 EMS computer may also be used locally tomanage the networked LRCS systems. Local operation is through the EMS software GUI.
ADCP-75-126 • Issue B • April 2002 • Section 1: OverviewPage 1-4©2002, ADC Telecommunications, Inc.3 SYSTEM FUNCTIONS AND FEATURESThis section describes various system level functions and features of the Digivance LRCS.3.1 Fiber Optic TransportOn an optional basis, the Digivance LRCS is available either with or without reverse pathdiversity. On non-diversity systems that do not use aWDM module, the HU is connected to theRU over apair of single-mode optical fibers. One fiber is used to transport the forward pathoptical signal. The other fiber is used to transport the reverse path optical signal. Because theoptical signal is digital, the input and output RF signal levels at the HU or the RU are notdependent on the level of the optical signal or the length of the optical fiber. Adiagram of thefiber optic transport system for anon-diversity system that does not include the WDM moduleis shown in Figure 1-2.Figure 1-2. Fiber Optic Transport without Diversity and Without WDM ModuleOn diversity systems that do not use aWDM module, the HU is connected to the RU over threesingle-mode optical fibers. One of the optical fibers is used to transport the forward path opticalsignal. Asecond optical fiber is used to transport the primary reverse path optical signal. Thethird optical fiber is used to transport the diversity reverse path optical signal. Adiagram of thefiber optic transport system with the diversity option is shown in Figure 1-3.The maximum length of the optical links 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.BTSHOST UNIT REMOTE UNIT16996-AFORWARD PATHREVERSE PATHCOAXFIBER OPTICLINKEBTSHOST UNIT REMOTE UNIT16996-AFORWARD PATHREVERSE PATHCOAXFIBER OPTICLINK
ADCP-75-126 • Issue B • April 2002 • Section 1: OverviewPage 1-5©2002, ADC Telecommunications, Inc.Figure 1-3. Fiber Optic Transport with Diversity and Without WDM ModuleThe optical wavelengths used in the system are 1550 nm for the forward path and 1310 nm forthe reverse path. Because different wavelengths are used for the forward and reverse paths, apair of bi-directional wavelength division multiplexers (WDM) may be used in applicationswhere it is desirable to combine the forward path and reverse path optical signals on asingleoptical fiber. One WDM may be mounted with the HU and the other WDM mounted with theRU. Adiagram of afiber optic transport system with aWDM application is shown inFigure 1-4.The WDMs are available as accessory items.Figure 1-4.

ADCP-75-126 • Issue B • April 2002 • Section 1: OverviewPage 1-6©2002, ADC Telecommunications, Inc.Because separate forward and reverse path optical inputs and outputs are provided at the HUand RU, aFree Space Optics (FSO) system (that meets the Digivance LRCS data rateperformance and BER requirements) may be used in applications where it is desirable to bridgean open span and where it is impractical to lay afiber optic cable. One FSO transceiver unit maybe mounted on the HU side of the open span and the other FSO transceiver unit may be mountedon the RU side of the open span. Asystem diagram of an FSO application is shown inFigure 1-5.FSO systems are available from various equipment manufacturers.Figure 1-5. Free Space Optics Application3.2 Control and Monitoring SoftwareThe Digivance EMS software supports system control and monitoring functions for both thelocal and remote service interfaces. The EMS software is stored on aCD-ROM and shippedseparately with each HU. Software installation consists of copying the software files from theCD-ROM to adesignated directory on the hard-drive of the EMS computer. The EMS softwaremay also be copied to the hard-drive of alaptop computer when alocal service interfaceconnection with aspecific HU or RU is required.The EMS software is used to provision and configure the system for operation. This includesselecting asitename, setting alarm thresholds, and setting forward and reverse path RF gainadjustments. The EMS software is also used to get alarm messages (individual or summary),data measurements, or to upgrade the HU/RU system software. All control and monitorfunctions (except software upgrade which can only be done using the EMS software GUI) canbe effected using either the NOC/NEM interface or the EMS 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 EMS software GUI.EBTSHOST UNIT REMOTE UNIT16999-ACOAXFSOTX/RXFSOTX/RXPRIMARY REVERSE PATHFORWARDPATHFORWARDPATHPRIMARY REVERSE PATHFREE SPACE OPTICS LINK

ADCP-75-126 • Issue B • April 2002 • Section 2: DescriptionPage 2-3©2002, ADC Telecommunications, Inc.Figure 2-1. Host Unit2.2 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.2.3 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 information may be accessed remotelythrough the NOC/NEM interface or locally through the EMS software GUI.2.4 RF Signal ConnectionsThe RF signal connections between the HU and the BTS are supported through either two (non-diversity unit) or three (diversity unit) N-type female connectors. On non-diversity units, oneconnector is used for the forward path RF signal. The other connector is used for the reversepath RF signal.

The HU should be as close as possible to the BTS to minimizecable 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 30 dBand can be set in 1dB increments. The attenuators are software controlled and are adjustedthrough the NOC/NEM interface or the EMS software GUI.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. An external attenuator isrequired 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 from0dB of gain (attenuator set to 30 dB) to 30 dB of gain (attenuator set to 0dB) to the outputsignal at the HU. The host diversity reverse path attenuator provides the same function as thehost reverse path attenuator but for the diversity reverse path.2.6 Propagation DelayThe HU forward, reverse, and diversity reverse path propagation delays may be adjusted in 1µsincrements within arange of 0–63 µs. The propagation delay is software controlled and may beadjusted through the NOC/NEM interface or the EMS software GUI.2.7 Optical ConnectionOptical connections between the HU and the RU (STM) are supported through either two (non-diversity unit) or three (diversity unit) SC-type optical connector ports. On non-diversity units,one port is used for connecting the forward path optical signal and the other port is used forconnecting the primary reverse path optical signal. On diversity units, athird optical port is usedfor connecting the diversity 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 EMS computer.2.9 Service Interface ConnectionThe service interface connection between the HU and the Digivance EMS computer issupported by asingle DB-9 female connector.
