ADMONISHMENTS

                 Important safety admonishments are used throughout this manual to warn of possible hazards
                 to persons or equipment. An admonishment identifies a possible hazard and then explains
                 what 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 use
                 of the triangular alert icon (seen below), and are listed in descending order of severity of injury
                 or damage and likelihood of occurrence.

                 Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
                 injury, 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 severe
                 personal 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 minor
                 personal 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 when
                 installing or using electrically-powered equipment. To prevent electrical shock, never install
                 or use electrical equipment in a wet location or during a lightning storm.

                 Warning: The DRU is powered by 48 VDC power which is supplied over customer-provided
                 wiring. 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 a Class 1 Laser according to FDA/CDRH rules. Laser radiation
                 can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do
                 not look directly into the optical adapters of any digital unit or exposure to laser radiation
                 may result. An optical power meter should be used to verify active fibers. A protective cap or
                 hood MUST be immediately placed over any radiating adapter or optical fiber connector to
                 avoid the potential of dangerous amounts of radiation exposure. This practice also prevents
                 dirt particles from entering the adapter or connector

                 Danger: Do not look into the ends of any optical fiber. Exposure to laser radiation may result. Do
                 not 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. Fibers
                 may be permanently damaged if bent/curved to a radius of less than 2 inches (50 mm).

1   SYSTEM FUNCTIONAL OVERVIEW

           The Digivance ICS is a digitally distributed antenna system that provides in-building coverage
           for wireless phone systems operating within the 800 MHz frequency bands used for SMR and
           NPSPAC (SMR+) communications. Large buildings typically interfere with the transmission
           or reception of cellular phone system signals by imposing high attenuation losses on RF
           signals. The Digivance ICS is designed to overcome the attenuation losses that make wireless
           communications within buildings or structures difficult or impossible. With the Digivance
           ICS, wireless phone RF signals can be distributed to the interior areas of any building or
           structure 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. The
           basic system consists of the Digital Host Unit (DHU), Digital Remote Unit (DRU), and when
           additional capacity or longer fiber runs are required, the Digital Expansion Unit (DEU). In
           addition, a local interface device and a remote interface device must be used as needed to
           interface 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 this
           publication, the BTS could be either a microcell or a cell site base station. When the BTS is
           co-located (microcell interface) with the DHU, a local interface over coaxial cable is possible.
           An interface device (ancillary product) must be used to provide the proper input and output RF
           signal levels between the BTS and the DHU. When the BTS is not co-located (cell site base
           station interface) with the DHU, a remote interface using a donor antenna is required. An
           interface device (ancillary product) must be used to provide the proper input and output RF
           signal levels between the donor antenna and the DHU.

           In the forward path, the DHU receives RF signals from the BTS. The DHU digitizes the RF
           signals 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. The
           DHU converts the optical signals back to the original RF signal format for transmission to the
           BTS.


1.3 Interface With Cellular Phones

           The DRU interfaces (through an external antenna) with the cellular phones. In the reverse
           path, the DRU receives RF signals from each cellular phone. The DRU digitizes the RF
           signals and then converts them to digital optical signals for transport to the DHU. In the
           forward path, the DRU receives digital optical signals from the DHU. The DRU converts the
           optical signals back to the original RF signal format for transmission to the cellular phones. A
           small external antenna is connected to the DRU to transmit and receive RF signals to and from
           the cellular phones.

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 to
                transport the forward path optical signal. The other fiber is used to transport the reverse path
                optical signal. Because the optical signal is digital, no adjustments to the optical signal level
                are required at the DRU or the DHU as long as the BER is adequate. Either 62.5 or 50 micron
                core multi-mode optical fiber; or 9 micron core single-mode optical fiber may be used for the

                                                                            ADCP-75-136 • Issue 1 • November 2002




           optical transport connection. With 62.5 micron core multi-mode fiber , the optical path may be
           up to 500 meters in length. With 50 micron core multi-mode fiber, the optical path may be up
           to 750 meters in length. With 9 micron core single-mode fiber, the optical path may be up to
           10 kilometers in length. Single- and multi-mode fibers may be used in the same system. The
           optical 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 more
           DRU’s without having to install additional DHU’s. Each DHU is equipped with six optical
           ports. If more than six DRU’s are required by the application, a DEU may be connected to one
           of the DHU optical ports which expands that port to six ports. If still more optical ports are
           required, then a second DEU may be connected to the DHU; or a second DEU may be
           connected to the first DEU. The ability to cascade DEU’s in parallel or in series provides
           unlimited flexibility. It is physically possible to connect an unlimited number DRU’s to the
           DHU through the installation of DEU’s. The maximum number of DRU’s that can connected
           to 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 supplied
           through a standard three-conductor AC power cord. The DRU is powered by 34–48 Vdc
           which is supplied by either the DHU, DEU, or an ac/dc wall-mount style converter. When the
           DRU is powered by the DHU or DEU, the power is fed through a category 3 or 5 cable
           terminated 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 is
           normal or if a fault 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 a customer
           provided external alarm system. This could be a local system or automatic call-out system.

                                                     Figure 2. Digital Host Unit

                2.1.1     Primary Components

                The DHU consists of two electronic circuit board assemblies, a power supply assembly, and a
                fan assembly that are mounted within a powder-coated sheet metal enclosure. The metal
                enclosure provides a mounting point for the electronic assemblies, serves as a heat sink, and
                controls RF emissions. Except for the fan units and optical transceivers, the DHU components
                are not field replaceable. The DHU is designed for use within a non-condensing indoor
                environment such as inside a wiring closet or cabinet. All controls, connectors, and indicators
                are mounted on the DHU front panel for convenient access. Cable management functions for
                the power and fiber optic cables are provided by a cable management tray that extends
                outward from the DHU front panel.

                                                                          ADCP-75-136 • Issue 1 • November 2002




2.1.2    Mounting

The DHU may be used in both rack-mount and wall-mount applications. For rack mount
applications, a pair of reversible mounting brackets is provided that allow the DHU to be
mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. When rack-mounted,
the front panel of the DHU is flush with the front of the rack and the cable management tray
extends 3.9 inches (99 mm) beyond the front panel. For wall-mount applications, a pair of
holes is provided in the cable management tray which allow the DHU to be mounted on any
flat vertical surface. The DHU should be oriented with the front panel facing upward when
wall-mounted. Fasteners are provided for rack-mount applications.

2.1.3    Fault Detection and Alarm Reporting
The DHU detects internal circuitry faults and optical port faults. Various front panel Light
Emitting Diode (LED) indicators turn from green to red or yellow if a fault is detected or an
optical input is lost. A set of alarm contacts (normally open and normally closed) are also
provided for reporting an alarm to an external alarm system when a fault is detected. Both
major alarm (all fault conditions except high temperature) and minor alarm (high temperature
fault condition) contacts are provided.

2.1.4    RF Signal Connections
The RF signal connections with the BTS are supported through two type N female connectors. One
connector is used for coaxial cable connection of the forward path RF signal. The other connector is
used for coaxial cable connection of the reverse path RF signal. In most installations, the DHU will
not connect directly to the BTS but will be connected to an interface device (ancillary product).
The DHU requires a composite forward path RF signal level of –20 dBm or lower. An
overdrive limiter protects the system against excessive inputs but does not function during
normal operation. The DHU does not have Automatic Gain Control (AGC).

2.1.5    Optical and Electrical Connections
The optical and electrical connections with the DRU’s and DEU’s are supported by six optical and six
electrical ports. Each optical and electrical port includes a status LED, a small form factor LC-type optical
transceiver, an RJ-45 DC power jack, and a port enable/disable switch. Each transceiver is color-coded to
identify whether it supports single-mode (blue) or multi-mode (black/beige) fiber. An optical port may be
connected to a DRU, a DEU, or not used. An electrical port may be connected to a DRU or not used.
Unused ports are disabled via the corresponding port enable/disable switch. When disabled, the port LED
is off, the alarm reporting function is disabled, the laser is off, and the DC power is off. Enabling the
enable/disable switch activates all functions. The modular optical transceivers are available separately as
accessory items and are field replaceable.

2.1.6    Powering
The DHU is powered by 120–240 Vac (50–60 Hz) power which is supplied through a standard
three-conductor AC power cord. The power cord is provided with the DHU and is 98 inches
(2.5 meters ) long. A resetable circuit breaker/On-Off switch is provided at the unit front
panel. The switch applies power to the DHU internal power supply.

                2.1.7     Cooling
                Continuous air flow for cooling is provided by dual fans mounted on the right side of the
                housing. A minimum of 3 inches (76 mm) of clearance space must be provided on both the
                left and right sides of the DHU for air intake and exhaust. An alarm is provided that indicates
                if a high temperature condition (>50º C/122º F) occurs. The fans may be field-replaced if
                either fan fails.

                2.1.8     User Interface

                The DHU user interface consists of the various connectors, switches, terminals, and LEDs that
                are provided on the DHU front panel. The DHU user interface points are described in Table 1
                and indicated in Figure 3.
