Throughout this publication, all items referenced as“accessory items” are not furnished with the basic product and must be purchased separately. 2 SMR 20 WATT SYSTEM OVERVIEWThe Digivance SMR 20 Watt System is an RF signal transport system that provides long-rangeRF coverage in areas where it is impractical to place an Enhanced Base Transceiver Station(EBTS) at the antenna site. High real estate costs and community restrictions on tower andequipment locations often make it difficult to install the EBTS at the same location as theantenna. The Digivance system is designed to overcome equipment placement problems byallowing base stations to be hubbed at a central location while placing remote antennas atoptimum locations with minimal real estate requirements. With the Digivance system, 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 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, primary interface panels and expansion panels (for interfacing multiple HU’s

Each EBTS provides the RF channelinputs and outputs for a designated sector. Interfacing the HU with multiple EBTS’s willgenerally require installation of the SMR Interface Panels which are accessory products for theDigivance system. Two types of Interface Panels are available: the Primary Interface Panel and the Expansion Panel.The Primary Interface Panel provides attenuation of the forward path signal to the level requiredfor input to the Host Unit. The Primary Interface Panel also provides forward and reverse pathcombining and splitting to permit up to 6 EBTS’s to be connected to a single Host Unit. A typicalPrimary Interface Panel configuration with multiple EBTS’s connected to a single Host Unit isshown in Figure 1-2. Figure 1-2. EBTS/HU Interface with Primary Interface PanelThe Expansion Panel is used in conjunction with the Primary Interface Panel when the HostUnit must be interfaced with more than six EBTS’s. Each Primary Interface Panel can supporttwo Expansion Panels and each Expansion Panel can support up to six EBTS’s. Whenconfigured as shown in Figure 1-3, a total of eighteen EBTS’s can be interfaced with one HostUnit. 18820-AHOST UNIT3 x 13 x 1ENHAN. BASETRANSCEIVERSTATIONSENHAN.

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. Figure 1-4. 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. TheDigivance EMS provides the various control and monitoring functions required for remotemanagement of multiple 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.

ADCP-75-159 • Issue 1 • August 2003 • Section 1: OverviewPage 1-6© 2003, ADC Telecommunications, Inc.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. The EMS desktop computer may also be usedlocally to manage the networked Digivance systems. Local operation is through the EMSsoftware GUI. Figure 1-5. 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.

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 SMR Digivance systemprovides an optical budget of 17 dB (typical) when used with 9/125 single-mode fiber. 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-75-159 • Issue 1 • August 2003 • Section 1: OverviewPage 1-9© 2003, ADC Telecommunications, Inc.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 EBTS.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 (requirespedestal kit). Slots are provided within the cabinet for the STM and LPA modules. Storagespools are provided for storing short lengths of excess fiber slack.

ADCP-75-159 • Issue 1 • August 2003 • Section 2: DescriptionPage 2-3© 2003, ADC Telecommunications, Inc.1 INTRODUCTIONThis section describes the basic components of the Digivance SMR 20 Watt system includingthe Host Unit (HU), the Remote Unit (RU), and the Digivance Element Management System(EMS). Also described are various accessory items including the Interface Panels, WavelengthDivision Multiplexer (WDM) system, and Coarse Wavelength Division Multiplexer (CWDM)system. The RU is an assembly that consists of a cabinet (for outdoor applications) or mountingshelf (for indoor applications), a Spectrum Transport Module (STM), and a Linear PowerAmplifier (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 EBTS servicing unit for the Digivance system. TheHU provides the following basic functions: • Provides a gain adjustable RF interface with the EBTS. • 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. The RF connectors, optical connectors,alarm output connectors, DC power terminal strip, and grounding lug are mounted on the HUrear side. The On/Off power switch, LED indicators, service interface connector, and ControlerArea Network connectors are mounted on 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.Fasteners are provided for securing the HU to the equipment rack.

ADCP-75-159 • Issue 1 • August 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 EBTS 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 installations where multiple EBTS’s will be connected to a single HU, it willusually be necessary to install a Primary Interface Panel and an Expansion Panel (accessoryitems) to support the interface between the HU and the EBTS. The HU should be as close aspossible to the EBTS 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 20 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. 17.1 INCHES(433 mm)3.5 INCHES(88 mm)12.2 INCHES(311 mm)FRONT PANELMOUNTINGBRACKET(BOTH SIDES)17857-A

ADCP-75-159 • Issue 1 • August 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 –20 dBm to–40 dBm can be adjusted to produce maximum power output. Additional external attenuationis required if the input signal level is greater than –20 dBm. The host reverse path attenuator adjusts the level of the output RF signal and will add from+10 dB of gain (attenuator set to 20 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 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.
