Throughout this publication, all items referenced as“accessory items” are not furnished with the basic product and must be purchased separately. 2 1900 MHZ 20 WATT SYSTEM OVERVIEWThe Digivance 1900 MHz 20 Watt System is an RF signal transport system that provides long-range RF coverage in areas where it is impractical to place a Base 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 a central 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 a Digivance 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 (EMS), a PC-based software program.In addition, various accessory items are available separately including a passive WavelengthDivision Multiplexer (WDM) system, an active Coarse Wavelength Division Multiplexer(CWDM) system, conditioning and duplexing panels (for interfacing the HU with the BTS),

ADCP-75-158 • Issue 1 • July 2003 • Section 1: OverviewPage 1-3© 2003, ADC Telecommunications, Inc.2.2 Base Transceiver Station to Host Unit InterfaceThe HU interfaces with the BTS which provides the RF channel inputs and outputs for adesignated sector. 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. A typical 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 a duplexed 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 a local serviceinterface capability as shown in Figure 4. The primary component of the local interface is a PC-type laptop computer loaded with the Digivance Element Management System (EMS) software.The EMS provides the various control and monitoring functions required for local managementof each Digivance system. The EMS computer can be directly connected to either the HU or RUthrough the computer’s RS-232 port. Operation is done through the EMS Graphical UserInterface (GUI). The GUI consists of a series of screens from which the user selects the desiredoption or function. An RS-232 service port is provided on both the HU and the RU forconnecting the EMS computer. 18515-ARFRFRFRFRFBASETRANSCEIVERSTATIONCOAXIALCABLESCOAXIALCABLESHOST UNITHOST UNITHOST UNITCONDITIONINGPANELDUPLEXINGPANEL

Local Service Interface2.5 Remote NOC InterfaceRemote communications between a Network Operations Center (NOC) and a networkedgrouping of multiple Digivance systems is supported by a remote NOC interface capability asshown in Figure 1-5. The primary component of the remote NOC interface is a PC-type desktopcomputer loaded with the Digivance Element Management System (EMS) software. EMSprovides the various control and monitoring functions required for remote management ofmultiple Digivance systems through a NOC. A Controller 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 a T1 system or other medium. The EMScomputer’s RS-232 port #2 interfaces with the T1 system equipment. The T1 equipment mustbe capable 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 a VT100 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.

Remote NOC Interface3 SYSTEM FUNCTIONS AND FEATURESThis section describes various system level functions and features of the Digivance System. 3.1 Fiber Optic TransportIn a typical Digivance 20 Watt system with a single HU and RU, the HU is connected to the RUover a pair of single-mode optical fibers. One fiber is used to transport the forward path opticalsignal. The other fiber is used to transport the reverse path optical signal. 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. A diagram of the fiber optictransport system for a typical Digivance system is shown in Figure 1-6. The Digivance 20 Wattsystem does not support reverse path diversity at this time. 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.

ADCP-75-158 • Issue 1 • July 2003 • Section 1: OverviewPage 1-7© 2003, ADC Telecommunications, Inc.Figure 1-6. Standard Fiber Optic TransportIn some applications, it may be desirable or necessary to combine the forward path and reversepath optical signals from a single HU/RU pair onto a single optical fiber. This can beaccomplished by using a passive bi-directional Wavelength Division Multiplexer (WDM)system. The optical wavelengths used in the Digivance system are 1550 nm for the forward pathand 1310 nm for the reverse path. Because the Digivance system uses different opticalwavelengths for the forward and reverse paths, both signals can be combined on a single opticalfiber. One WDM module is mounted with the HU and the other WDM module is mounted withthe RU as shown in Figure 1-7. The WDM system is available as an accessory item. 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 a single optical fiber. This can beaccomplished by using an active Coarse Wavelength Division Multiplexer (CWDM) system. Upto four Digivance systems may be configured to operate over a single optical fiber. A CWDMmodule 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 a new 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

ADCP-75-158 • Issue 1 • July 2003 • Section 1: OverviewPage 1-9© 2003, ADC Telecommunications, Inc.3.2 Control and Monitoring SoftwareThe Digivance EMS software supports control and monitoring functions for both the local andremote service interfaces. The EMS software is stored on a CD-ROM which is included with theEMS software package. Software installation consists of copying the software files from theCD-ROM to a designated directory on the hard-drive of the EMS computer. The EMS software is used to provision and configure the Digivance system for operation. Thisincludes selecting a sitename, setting alarm thresholds, and setting forward and reverse path RFgain adjustments. The EMS 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 EMS softwareGUI) can be 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 a fault is detected. In addition, normally openand normally closed alarm contacts (for both major and minor alarms) are provided at the HUfor connection to a customer-provided external alarm system. All alarms can also be accessedthrough the NOC/NEM interface or the EMS software GUI. 3.4 PoweringThe HU is powered by ±24 or ±48 VDC and must be hard-wired to a local office battery powersource through a fuse panel. A screw-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 connected to an AC powersource through a 20 Amp breaker box. A three-wire cable is provided for the AC powerconnections. A 120 VAC outlet should be installed near the RU for powering test equipment orpower tools. In certain applications, it may be necessary to install a surge protector (notprovided) in the AC power feed to prevent equipment damage from AC power spikes. 3.5 Equipment Mounting and ConfigurationThe HU is designed for mounting in a non-condensing indoor environment such as inside awiring closet or within an environmentally-controlled cabinet. The HU is intended for rack-mount applications and may mounted in either a 19- or 23-inch WECO or EIA equipment rack,usually within 20 feet of the BTS.The outdoor RU is designed for mounting in an outdoor environment. The outdoor RU consistsof a Spectrum Transport Module (STM), a Linear Power Amplifier (LPA) module, and a self-contained cabinet which houses the modular components and protects them from the elements.The RU cabinet is weather-tight but contact with salt-air mist should be avoided as it maydegrade the MTBF of the product. The outdoor cabinet can be mounted from a flat-verticalsurface, from a utility pole (requires pole-mount kit), or mounted on a pedestal (requires

ADCP-75-158 • Issue 1 • July 2003 • Section 2: DescriptionPage 2-3© 2003, ADC Telecommunications, Inc.1 INTRODUCTIONThis section describes the basic components of the Digivance 1900 MHz 20 Watt systemincluding the Host Unit (HU), the Remote Unit (RU), and the Digivance Element ManagementSystem (EMS). Also described are various accessory items including the InterFace Panels,Wavelength Division Multiplexer (WDM) system, and Coarse Wavelength Division Multiplexer(CWDM) system. The RU is an assembly that consists of a cabinet (for outdoor applications) ormounting shelf (for indoor applications), a Spectrum Transport Module (STM), and a LinearPower 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 a gain adjustable RF interface with the BTS. • Provides a fiber optic interface with the RU. • Digitizes the forward path composite RF signal. • Converts the digitized forward path RF signal to a digital optical signal. • Converts the digitized reverse path optical signal to a digitized RF signal. • Converts the digitized reverse path RF signal to a composite RF signal. • Signals alarm information to an external alarm system through relay contact closures• Provides an RS-232 interface for connecting the EMS computer. • Provides a CAN interface for networking multiple HUs. 2.1 Primary ComponentsThe HU consists of an electronic circuit board assembly and a fan assembly that are mountedwithin a powder-paint coated sheet metal enclosure. The enclosure provides a mounting 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 a non-condensing indoorenvironment such as inside a wiring 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 a cablemanagement tray that extends outward from the HU front panel. 2.2 MountingThe HU is intended for rack-mount applications. A pair of reversible mounting brackets isprovided that allow the HU to be mounted in either a 19-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-75-158 • Issue 1 • July 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 a fault is detected. A set of alarm contacts (normally open andnormally closed) are provided for reporting an alarm to an external alarm system when a fault 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 opticalinterface 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 EMS 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 current 20 Watt system does not support a diversityreverse path. In most installations, it is usually necessary to install a Conditioning 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 0 to 31 dBand can be set in 1 dB increments. The attenuators are software controlled and are adjustedthrough the NOC/NEM interface or the EMS 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-75-158 • Issue 1 • July 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 a nominal composite signal level of –9 dBm to –40dBm can be adjusted to produce maximum power output. Additional external attenuation isrequired if the input signal level is greater than –9 dBm. The host reverse path attenuator adjusts the level of the output RF signal and will add from–1 dB of gain (attenuator set to 31 dB) to +30 dB of gain (attenuator set to 0 dB) to the RFoutput signal at the HU. 2.6 Propagation DelayThe HU forward and reverse path propagation delays may be adjusted in 0.1 µsec incrementswithin a range of 0 to 63 µs. The propagation delay is software controlled and may be adjustedthrough the NOC/NEM interface or the EMS 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 bya pair 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 a single Digivance EMS computer. 2.9 Service Interface ConnectionThe service interface connection between the HU and the Digivance EMS computer issupported by a single DB-9 female connector. The service connector provides an RS-232 DTEinterface. When multiple HUs are networked together, the supporting EMS computer may beconnected to the service connector of any one of the networked HUs. 2.10 PoweringThe HU is powered by ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The power is fed tothe HU through a screw-down type terminal strip located on the rear side of the unit.

Remote Unit Outdoor Cabinet3.1 Primary ComponentsThe RU outdoor cabinet consists of the enclosure, mounting slots for the STM and LPA modules,connectors and a wiring harness for interfacing the STM and LPA modules, a mounting slot foreither the WDM or CWDM module (accessory items), lightning protector, and two fiber storagespools. The RU outdoor cabinet is designed for use in an outdoor environment. Opening thehinged door provides full height and width access to the interior of the enclosure to facilitatemodule and cable installation. The enclosure is constructed of heavy gauge aluminum and is painted putty white for corrosionprotection. Connection and/or entry points are provided in the bottom of the enclosure for theantenna coaxial cable, fiber optic cable, and AC power cable. Vent openings are provided in thebottom of the enclosure to permit air exchange for cooling. The RU cabinet is weather-tight butcontact with salt-air mist should be avoided as it may degrade the Mean Time Between Failure(MTBF) of the product. Drain holes in the bottom of the cabinet allow any moisture that doesenter the cabinet to drain out. The cabinet door is equipped with a sturdy latch so that theenclosure may be padlocked to prevent unauthorized entry. A door open switch is provided sothat a major alarm is generated whenever the cabinet door is opened.

A special mounting bracket is provided with each enclosure.Installation consists of securing the bracket to the mounting surface and then hanging theenclosure from the bracket. The mounting bracket may be attached to a variety of surfaces suchas wood, concrete, or masonry. Various fasteners including hex-head capscrews, tee-nuts, andconcrete anchors are provided. A pole-mount kit (accessory item) is available for mounting thecabinet from a utility pole. A pedestal-mounting kit (accessory item) is available for mountingthe cabinet on a flat horizontal surface. 3.3 STM and LPA Module InstallationTwo mounting slots are provided within the RU cabinet for installing the STM and LPAmodules. The mounting slots include tracks that guide each module into the installed position.Separate mounting slots are provided for STM and LPA modules. Two D-sub connectors (onemale, one female) are located at the rear of each mounting slot. Each mounting slot connectormates with a corresponding D-sub connector located on the rear side of each module. A wiringharness links the mounting slot connectors together. The connectors and the attached wiringharness provide the electrical interface between the STM and LPA modules. The modules areheld in the installed position with captive screws. 3.4 WDM and CWDM InstallationA mounting slot is provided within the RU cabinet for installing a WDM or CWDM remotemodule (accessory items). Each module is equipped with push-pull type fasteners for securingthe module to the mounting slot. A power cable is included with the cabinet for providing powerwhen a CWDM module is installed. Fiber storage spools are provided for storing excess pigtailand/or patch cord slack. 3.5 Fiber Optic Cable EntryA plastic cord connector is provided in the exterior bottom side of the RU cabinet for routing afiber optic cable into the enclosure. The cord connector provides cable strain relief and awatertight seal at the fiber optic cable entry point. As the connector nut is tightened, a softneoprene bushing compresses to tightly grip the cable without applying excessive force to thefibers. The cord connector can accommodate cables that range from 0.375 to 0.875 inches (10 to23 mm) in diameter. A spool is provided directly above the fiber optic cable entry hole forstoring excess pigtail slack. In a typical installation, the connectorized end of a multi-fiber outside plant cable is routed intothe enclosure through the cord connector and the individual fibers are broken out into pigtails.The pigtails are connected to the optical ports on the STM and the excess pigtail slack is storedon the fiber storage spool. The stub end of the cable is routed to an external splice enclosure (notprovided) for splicing to the fiber optic cable.
