An admonishment identifies apossible hazard and then explainswhat may happen if the hazard is not avoided. The admonishments —in the form of Dangers,Warnings, and Cautions —must be followed at all times. These warnings are flagged by useof the triangular alert icon (seen below), and are listed in descending order of severity of injuryor damage and likelihood of occurrence.Danger:Danger is used to indicate the presence of a hazard that will cause severe personalinjury, death, or substantial property damage if the hazard is not avoided.Warning:Warning is used to indicate the presence of a hazard that can cause severepersonal injury, death, or substantial property damage if the hazard is not avoided.Caution:Caution is used to indicate the presence of a hazard that will or can cause minorpersonal injury or property damage if the hazard is not avoided.GENERAL SAFETY PRECAUTIONS The following general admonishments apply throughout the procedures in this manual.Warning:Wet conditions increase the potential for receiving an electrical shock wheninstalling or using electrically-powered equipment. To prevent electrical shock, never installor use electrical equipment in awet location or during alightning storm.Warning:The DRU is powered by 48 VDC power which is supplied over customer-providedwiring. To prevent electrical shock when installing or modifying the DRU power wiring,disconnect the wiring at the power source before working with uninsulated wires or terminals.Danger:This equipment uses aClass 1Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Donot look directly into the optical adapters of any digital unit or exposure to laser radiationmay result. An optical power meter should be used to verify active fibers. Aprotective cap orhood MUST be immediately placed over any radiating adapter or optical fiber connector toavoid the potential of dangerous amounts of radiation exposure. This practice also preventsdirt particles from entering the adapter or connectorDanger:Do not look into the ends of any optical fiber. Exposure to laser radiation may result. Donot assume laser power is turned-off or the fiber is disconnected at the other end.Danger:Always allow sufficient fiber length to permit routing without severe bends.

ADCP-75-136 • Issue 1 • November 2002 Page 1 ©2002, ADC Telecommunications, Inc.1 SYSTEM FUNCTIONAL OVERVIEW The Digivance ICS is adigitally distributed antenna system that provides in-building coveragefor wireless phone systems operating within the 800 MHz frequency bands used for SMR andNPSPAC (SMR+)communications. Large buildings typically interfere with the transmissionor reception of cellular phone system signals by imposing high attenuation losses on RFsignals. The Digivance ICS is designed to overcome the attenuation losses that make wirelesscommunications within buildings or structures difficult or impossible. With the DigivanceICS, wireless phone RF signals can be distributed to the interior areas of any building orstructure to eliminate dead spots and improve reception.1.1 Basic System Components The basic components of the Digivance ICS and their functions are shown in Figure 1. Thebasic system consists of the Digital Host Unit (DHU), Digital Remote Unit (DRU), and whenadditional capacity or longer fiber runs are required, the Digital Expansion Unit (DEU). Inaddition, alocal interface device and aremote interface device must be used as needed tointerface the DHU with the cellular system Base Transceiver Station (BTS).1.2 Interface With BTS The DHU interfaces, either locally or remotely, with the BTS. As referenced in thispublication, the BTS could be either amicrocell or a cell site base station. When the BTS isco-located (microcell interface) with the DHU, alocal interface over coaxial cable is possible.An interface device (ancillary product) must be used to provide the proper input and output RFsignal levels between the BTS and the DHU. When the BTS is not co-located (cell site basestation interface) with the DHU, aremote interface using a donor antenna is required. Aninterface device (ancillary product) must be used to provide the proper input and output RFsignal levels between the donor antenna and the DHU.In the forward path, the DHU receives RF signals from the BTS. The DHU digitizes the RFsignals and then converts them to digital optical signals for transport to the DEU’s and DRU’s.In the reverse path, the DHU receives digital optical signals from the DRU’s and DEU’s. TheDHU converts the optical signals back to the original RF signal format for transmission to theBTS.1.3 Interface With Cellular Phones The DRU interfaces (through an external antenna) with the cellular phones. In the reversepath, the DRU receives RF signals from each cellular phone. The DRU digitizes the RFsignals and then converts them to digital optical signals for transport to the DHU. In theforward path, the DRU receives digital optical signals from the DHU. The DRU converts theoptical signals back to the original RF signal format for transmission to the cellular phones. Asmall external antenna is connected to the DRU to transmit and receive RF signals to and fromthe cellular phones.

System Overview Functional Block Diagram 1.4 Digital Fiber Optic Transport The DHU is connected to each DRU unit over a pair of either multi-mode or single-mode(depending on the type of optical transceiver specified) optical fibers. One fiber is used totransport the forward path optical signal. The other fiber is used to transport the reverse pathoptical signal. Because the optical signal is digital, no adjustments to the optical signal levelare required at the DRU or the DHU as long as the BER is adequate. Either 62.5 or 50 microncore multi-mode optical fiber; or 9 micron core single-mode optical fiber may be used for the
ADCP-75-136 • Issue 1 • November 2002 Page 3 ©2002, ADC Telecommunications, Inc.optical transport connection. With 62.5 micron core multi-mode fiber , the optical path may beup to 500 meters in length. With 50 micron core multi-mode fiber, the optical path may be upto 750 meters in length. With 9micron core single-mode fiber, the optical path may be up to10 kilometers in length. Single- and multi-mode fibers may be used in the same system. Theoptical fibers must be terminated with duplex LC connectors for connection with the DHU,DEU’s and DRU’s.1.5 Capacity for Expansion and Extended Runs The DEU enables 6-way expansion of any optical port. This makes it possible to add moreDRU’s without having to install additional DHU’s. Each DHU is equipped with six opticalports. If more than six DRU’s are required by the application, aDEU may be connected to oneof the DHU optical ports which expands that port to six ports. If still more optical ports arerequired, then asecond DEU may be connected to the DHU; or a second DEU may beconnected to the first DEU. The ability to cascade DEU’s in parallel or in series providesunlimited flexibility. It is physically possible to connect an unlimited number DRU’s to theDHU through the installation of DEU’s. The maximum number of DRU’s that can connectedto the DHU is limited only by the cumulative noise effect caused by antenna combining.1.6 Power Requirements The DHU and DEU are each powered by 120–240 Vac (50–60 Hz) power which is suppliedthrough astandard three-conductor AC power cord. The DRU is powered by 34–48 Vdcwhich is supplied by either the DHU, DEU, or an ac/dc wall-mount style converter. When theDRU is powered by the DHU or DEU, the power is fed through acategory 3 or 5 cableterminated with male RJ-45 connectors.1.7 Fault Detection and Alarm Reporting LED indicators are provided on the front panel of the various units to indicate if the system isnormal or if afault is detected. In addition, normally open and normally closed alarm contacts(for both major and minor alarms) are provided at the DHU for connection to acustomerprovided external alarm system. This could bealocal system or automatic call-out system.
