INTRODUCTION
The SCS dual-band remote unit (RU) is a low power, non-diversity, self-contained remote unit
that interfaces with two Digivance LRCS/SCS host units over an optical fiber link. The dualband RU consists of an environmentally-sealed enclosure and four electronic modules that are
housed within the enclosure. Excess heat is dissipated using a passive cooling system which
eliminates the need for cooling fans. The low profile design of the RU requires minimal real
estate for installation. The enclosure may be mounted from a wall, pole, or overhead cable
(strand). Inside-pole mounting and underground vault installations are also possible. Separate
antennas (not provided) mount near the enclosure.

2.1
Primary Components
The dual-band RU consists of two Spectrum Transport Modules (STM) and two Linear Power
Amplifiers (LPA) mounted within an environmentally-sealed cast-aluminum enclosure. The two
STM’s provide optical-to-RF and RF-to-optical conversion and digitizing functions; alarm,
control, and monitoring functions; power conversion functions; and RF filtering and interface
functions. The two LPA’s amplify the forward path RF signals. Each STM works in conjunction
with an LPA and each STM/LPA pair works independently of the other. The aluminum
enclosure provides a mounting point for the STM and LPA electronic assemblies, controls RF
emissions, seals out dirt and moisture, and provides passive cooling. The electronic assemblies
are not user replaceable or accessible. All connectors and indicators are mounted on the bottom
of the RU enclosure for easy access.
2.2
Mounting
The RU may be mounted on a flat vertical surface (such as the side of a building) or on a utility
pole. A combination wall/pole mounting bracket is provided with each unit. Installation consists
of securing the bracket to the mounting surface and then hanging the enclosure from the
bracket. The bracket may be attached to a variety of surfaces such as wood, concrete, or
masonry. Various fasteners including hex-head capscrews, tee-nuts, and concrete anchors are
provided. A separate strand-mount kit (accessory item) is available if it is necessary to mount
the RU from a cable. Inside-pole mounting and underground vault installations are also
possible. Contact the Wireless TAC (see Section 8) for additional information.
2.3
Fault Detection and Alarm Reporting
The RU detects and reports various faults including remote unit fault, optical fault, output power
fault, temperature fault, and power amplifier fault. A single bottom-mounted Light Emitting
Diode (LED) indicator turns from off to red if a major fault is detected by either STM/LPA pair.
The status of each STM and LPA, the alarm state, and other fault information is summarized
and reported over the optical interface to the HU. Fault and alarm information may be accessed
at the HU through the EMS software GUI or remotely through the NOC/NEM interface or
SNMP interface.
2.4
Antenna Cable Connection
The antenna cable connections between the RU and the antennas are supported through two 50ohm N-type female connectors. Each antenna cable carries the forward and reverse path RF
signals between the antenna and the RU. An externally-mounted lightning protector is available
as an accessory. The antenna connector on the lightning protector may be either an N-type female
connector or a 7/16 mm DIN connector. The RU enclosure must be properly grounded for the
lighting protector to function properly. On an optional basis, the dual-band RU may be equipped
with one N-type connector (and internal diplexor) to support operation with a single antenna.
2.5
RF Signal Level Adjustment
The RU is equipped with digital attenuators for adjusting the signal level of the forward path RF
output signals. The remote forward path attenuators adjust the level of the output RF signals at
the RU antenna ports and will add from 0 to 31 dB of attenuation to each output signal level. The
attenuators can be set in 1 dB increments. The RF signal level for each STM/LPA pair is adjusted
separately. The attenuators are software controlled and are adjusted through the EMS software
GUI, the NOC/NEM interface, or SNMP interface.

2.6
Optical Connection
Fiber optic connections between the dual-band RU and the two associated HU’s (two HU’s are
required with a dual-band RU) are supported through two hardened optical ports. All dual-band
RU’s are equipped with two internally-mounted WDM’s. One port provides the optical fiber
connection for the combined forward and reverse path signals for HU #1. The other port provides
the optical fiber connection for the combined forward and reverse path signals for HU #2.
Each hardened optical port houses an SC adapter. A standard APC/SC type connector is
connected to the internal side of the optical port. The hardened optical port accepts drop cables
that are terminated with APC/SC hardened connectors. The optical ports are also compatible
with OptiTap® connectors manufactured by Corning Cable Systems Brands, Inc.
2.7
Powering
The RU is powered by 90 to 132 VAC (nominal 120) and 180 to 264 VAC (nominal 240), 47 to
63 Hz power. The AC power is supplied through a 20-foot three-wire power cable that is
provided with the enclosure. The power cable connects to a mini 3-pin power connector
mounted on the bottom of the RU enclosure. The power cable is rated for indoor or outdoor use
and must not be routed through conduit. Accessory power cables are also available separately in
lengths of 40, 60, or 100 feet.
The stub end of the power cable must be routed to an external junction box (not provided) for
connection to the AC power source. A circuit breaker rated at 15 Amps should be used to
provide overcurrent protection for the RU. It is also recommended that an external AC outlet
(not provided) be installed near the RU enclosure to power test equipment and power tools.
2.8
Grounding
A grounding terminal (hex socket capscrew and washer) is provided on the bottom of the
enclosure for connecting a grounding cable to the enclosure. A 1.5 meter #6 stranded copper
wire terminated with a ring terminal is provided with the RU for linking the enclosure to an
earth ground source.
2.9
Cooling
Passive cooling of the electronic assemblies is provided by conducting excess heat from the
internal electronic components to the aluminum enclosure. The heat is then dissipated to the
outside air by radiation and convection air flow over the enclosure’s external cooling fins. An
alarm is generated if a high temperature condition occurs within the enclosure. On an optional
basis, the RU may be ordered with solar shields that reduce the effect of solar loading on the
aluminum enclosure.
2.10 User Interface
The RU user interface consists of the connectors, grounding lug, and LED that are provided on
the bottom of the RU enclosure. The dual-band RU user interface points are indicated in
Figure 2 and described in Table 1.

horizontal cable (strand-mount). Mounting the RU from a cable requires an accessory kit not
included with the standard RU.
5.1
Before Mounting the RU
5.1.1
Mounting Considerations
Before mounting the RU, verify that the installation site is in conformance with the system
design plan (not documented here). If a system design plan has not been prepared, consult the
Wireless Technical Assistance Center (TAC) for technical assistance (see Section 8). The site
chosen must conform to all local codes and any permits required must be obtained prior to the
start of mounting. The location must be accessible and provide adequate parking for worker and
vehicle safety. The installed RU must not create a visual or physical obstruction to vehicular or
pedestrian traffic or block pole-climbing access.
The RU must be located as specified in the system design plan and must have ready access to
the specified AC power source. The site must provide adequate ventilation and must comply
with the RU environmental specifications. A minimum of 18 inches of clearance must be
provided on all sides (except the back) of the RU enclosure to allow free air circulation. In
addition, the bottom (cable entry end) and either the top, the front, or one of the sides must be
open to free air space. Adequate clearance must be allowed at the bottom of the enclosure to
provide access for attaching cables and for viewing the LED indicator.
5.1.2
Mounting Hardware Provided With RU Enclosure
The RU is shipped with the mounting hardware required for a typical wall-mount or pole-mount

INSTALLATION PROCEDURES
This section provides procedures for connecting the grounding, fiber optic, antenna, and AC
power cables. Installation of the dual-band RU may proceed separately from the installation of
the corresponding Host Unit. When the installation of the RU is completed, refer to the
Digivance SCS System Operation and Maintenance Manual (see Related Publications section)
for the system turn-up and test procedures.
The procedures in this section assume that the required OSP fiber optic cables have already
been routed between the host unit and the dual-band RU and that the required antenna has been
installed.
Danger: 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.
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.
Caution: Always allow sufficient length to permit routing of fiber optic cables without severe
bends. Optical cables may be permanently damaged if bent or curved beyond the minimum
recommended bend radius for the cable.
6.1
Installation Overview
Installation of the RU consists of the following basic steps:
Note: To insure that all connectors and ports remain dust-free during installation,
leave all dust caps and dust protectors in place until directed to remove them for
installation.
1. Connecting a grounding cable to the RU grounding point.
2. Routing the fiber optic drop cables to the RU.
3. Connecting the fiber optic drop cables to the RU optical ports.
4. Connecting the antenna coaxial cable(s) to the RU antenna port(s).
5. Installing the AC power cable and connecting it to the RU power port.
Note: If the unit will be horizontally mounted, provide drip loops for all cables that
connect to the RU enclosure.

6.3
Fiber Optic Cable Routing
Two fiber optic drop cables must be routed from an external splice enclosure or fiber access
terminal to the remote unit enclosure. The RU is equipped with a pair of WDM’s so only two
cables (one for each SCS system) are required for the optical signals. A pair of hardened optical
adapters (APC/SC) are used for the optical ports. Each drop cable must be terminated with an
APC/SC hardened optical connector. A routing diagram of a typical cable installation is shown
in Figure 11.
Note: The routing of an OSP fiber optic cable from the HU to a splice enclosure or fiber
access terminal in the vicinity of the SCS enclosure and the splicing or connecting of
selected OSP cable fibers to the drop cable is the responsibility of the installer.

Warning: 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 transmitter of any 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 transmitter or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the connector.
Use the following procedure to route the fiber optic drop cable:
1. Connect or splice the drop cables to the outside plant cable. Verify that there is sufficient
cable length to reach from the splice enclosure or fiber access terminal (not provided) to
the underside of the remote enclosure.
2. Mark the free end of each cable with the SCS system RF frequency (800 MHz, 1900 MHz,
or 800/900 MHz SMR) for identification.
3. Route the free end of each drop cable to the underside of the enclosure.
4. Leave sufficient slack to allow each cable to be connected and disconnected from the
enclosure optical port without bending or kinking the optical fibers.
5. Secure and protect cables per local practice.

6.4
Fiber Optic Cable Connection
The RU uses hardened adapters for the optical ports. A hardened adapter consists of a standard
SC adapter that is enclosed within a protective plastic housing. The housing provides sealed
environmental protection for the adapter. The opening to each optical port is sealed with a
threaded dust cap that prevents the entry of dirt and moisture. A 216B security tool (OSP216BKEY1) is required to remove the dust caps. The RU optical ports accept drop cables
terminated with APC/SC hardened connectors. The RU optical ports are also compatible with
OptiTap® connectors manufactured by Corning Cable Systems Brands, Inc.
Warning: 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 transmitter of any 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 transmitter or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the connector.
Use the following procedure to connect each optical fiber to the SCS enclosure optical port:
1. Locate the drop cables that were routed to the underside of the enclosure in Section 6.3.
Each drop cable should be marked with the system RF frequency.
2. Remove the dust cap from the optical connector on drop cable #1. The basic components
of the drop cable hardened connector are shown in Figure 12. The dust cap threads onto
the connector coupling nut. A pair of O-rings on the connector body provide a tight seal
when the dust cap is in place.

Antenna Cable Installation
A coaxial antenna cable must be routed from the antenna to the RU enclosure. The cable must
be terminated with the appropriate connector for connection to the RU antenna port or the
lightning protector (accessory). Dual-band units that support two antennas (ordering option) are
equipped with two antenna ports.
Note: To comply with Maximum Permissible Exposure (MPE) requirements, the
maximum composite output from the antenna cannot exceed 1000 Watts EIRP and the
antenna must be permanently installed in a fixed location that provides at least 6 meters
(20 feet) of separation from all persons.
Use the following procedure to install the antenna cable(s):
1. Remove the dust cap from the N-type female connector(s) located on the underside of the
enclosure as shown in Figure 16.
Note: On an optional basis, the RU may be equipped with two N-type connectors. This
allows each SCS system supported by the RU to have a separate antenna. If two N-type
connectors are present, the BAND 1 connector is for the lower frequency antenna cable.
The BAND 2 connector is for the higher frequency antenna cable.
2. If specified, connect a lightning protector (accessory) to the antenna port(s).
3. Route the coaxial antenna cable(s) from the antenna to the underside of the enclosure.
4. Cut the antenna cable(s) to the required length and terminate with the appropriate connector.
Note: If a lightning protector was not installed, the cable should be terminated with an Ntype female connector. If the lightning protector was installed, examine the connector on
the surge side of the protector. If the surge port connector is an N-type connector,
terminate the cable with an N-type male connector. If the surge port connector is a DIN
connector, terminate the cable with a 7/16 mm DIN male connector.
5. Connect the antenna cable(s) to the lightning protector(s) or to the antenna port(s).

AC Power Wiring Installation
A 20-foot connectorized 3-wire power cable is provided with the enclosure for the AC power
connections. The connectorized end of the power cable connects to the AC power port located
on the bottom of the enclosure. The stub end of the cable must be routed to an external junction
box (not provided). At the junction box, the power cable must be permanently connected to the
AC power system wiring.
Note: It is recommended that an AC outlet be installed near the enclosure for powering
tools and test equipment. This outlet must include a GFCI device for protection.
The AC power source must supply 120 or 240 VAC, 50 or 60 Hz, single-phase power through a
15 Amp circuit breaker. The AC power cable provides three wire leads for line, neutral, and
ground connections. The power cable must be routed from the enclosure to an electrical
junction box for connection to the AC power source. The power cable is rated for indoor or
outdoor use and must not be placed within electrical conduit as this will impede the cooling of
the cable during usage. The electrical junction box and any conduit, wire, and fittings required
must be provided by the installer. Use the following procedure to install the AC power wiring:
Note: All electrical work must comply with local codes and requirements. A locally
licensed electrical contractor is best qualified to perform this work. For additional
information, consult with the ADC Technical Assistance Center.

Danger: Use extreme caution when working with high voltage AC power. Ensure all power is
disconnected before working on power circuits.
1. Locate the AC power cable that is provided separately with the enclosure.
2. Route the power cable between the AC power port, located on the underside of the
enclosure and the nearest AC power junction box as shown in Figure 17. It may be
necessary to install a new junction box if an existing junction box is not available.

3. Secure the cable between the AC power port and the AC power junction box per local
practice. Leave sufficient slack in the cable to allow it to be easily connected and
disconnected from the AC power port.
Note: The power cable is rated for indoor or outdoor use and must not be placed within
electrical conduit as this will impede the cooling of the cable during usage. The cable run
distance to the AC power source must not exceed 100 feet.
4. Install any AC power supply wires that may be required between the AC junction box and
the AC circuit breaker box.
Note: It is recommended that an AC outlet be installed near the enclosure for powering
tools and test equipment. This outlet must include a GFCI device for protection.
5. Connect the AC power cable wires to the AC power supply wires. Refer to Figure 18 to
identify the color code and wire designations.
6. At the AC circuit breaker box, connect the AC power supply load wires to a 15 Amp
circuit breaker.

Danger: While trying to connect the AC power cable to the remote unit AC power port, it is
possible for the line terminal on the cable connector to contact the ground pin on the power
port. If the AC cable is energized, this will result in a direct short to ground for the AC power. To
avoid possible personal injury and equipment damage, always turn the AC power off before
connecting the AC power cable to the AC power port.
10. Connect the power cable connector to the AC power port.
11. Tighten coupling nut until the green band at the top of the connector body is visible.

MAINTENANCE PROCEDURES
Maintenance for the RU enclosure is limited to cleaning the hardened adapters as needed to
maintain optimal performance and lubricating the drop cable optical connector O-rings and the
optical port dust cap O-ring if they become dry.
7.1
Connector and Adapter Cleaning Procedures
A kit is required (FHD-ACC-CLNKIT1) for cleaning the hardened optical port adapters and the
drop cable connectors that are used with the RU. Refer to ADCP-96-067 (provided with the kit)
for instructions for cleaning both the drop cable connector and the optical port adapter and
connector.
7.2
O-Ring Lubrication
The O-rings used on the hardened connector and on the optical port dust cap are lubricated
when shipped from the factory to prevent damage during installation. If the O-rings become
excessively dry, they may require additional lubrication to prevent damage. Remove the O-rings
from the connector or dust cap and apply a small amount of lubricant directly to each ring. Then
reinstall the O-rings on the connector or dust cap. Apply only the recommended O-ring
lubricant (MST-ACC-LUBE1).
7.3
Painting
A brush-in-cap type bottle of paint (ACE-ACC-PTLAMD) is available for touching-up nicks
and scratches in the factory coat of paint. Lightly sand the area to be painted and then clean it
thoroughly to remove and dirt, dust, or foreign matter. Shake the paint bottle until thoroughly
mixed and then apply a light coat of paint to the damaged area using the small brush attached to
the cap. Wait until the paint is dry and the apply a second coat if necessary. When finished
painting, replace the paint bottle cap and tighten securely.
