Unpacking and Inspection
This section provides instructions for opening the shipping boxes, verifying that all parts have
been received, and verifying that no shipping damage has occurred. Use the following
procedure to unpack and inspect the HU and any accessories:
1. Open the shipping cartons and carefully unpack each component from the protective
packing material.
2. Check each component for broken or missing parts. If there are damages, contact ADC
(see section 6 at the end of this manual) for an RMA (Return Material Authorization) and
to reorder if replacement is required.
FIBER OPTIC CABLE ROUTING AND INSTALLATION GUIDELINES
The outside plant (OSP) fiber optic cables should be routed between the HU and RU and
terminated before the equipment is installed. A diagram of a typical fiber optic cable routing is
shown in Figure 3-1. At the HU, the OSP cable should be terminated at a fiber distribution panel
and spliced to pigtails. Patch cords may then be used to link the HU optical ports to the OSP
cable terminations. Whenever possible, a guideway such as the FiberGuide system should be
provided to protect the fiber optic patch cords from damage and to prevent excessive bending.
The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 7.

Figure 3-1. Typical Fiber Optic Cable Routing
When routed to the RU outdoor cabinet, the OSP fiber optic cable should be spliced to a
connectorized outdoor-rated cable (consisting of individual jacketed pigtails) which is then
routed into the outdoor cabinet. The individual pigtails can then be connected directly to the
STM optical ports. A connector is provided on the bottom of the RU outdoor cabinet to seal the
cable entry point and provide strain relief. The procedure for routing the fiber cable into an
outdoor cabinet and for connecting the pigtail leads to the STM is provided in the Digivance 20
Watt Outdoor Remote Unit Installation Instructions (ADCP-75-148).
When routed to RU indoor mounting shelf, the OSP cable should be terminated at a fiber
distribution panel and spliced to pigtails. Jumper patch cords may then be used to link the STM
optical ports to the OSP cable terminations. Whenever possible, a guideway such as the
FiberGuide system should be provided to protect the fiber optic patch cords from damage and to
prevent excessive bending. The procedure for connecting the OSP optical fibers to an STM
mounted in the indoor mounting shelf is provided in the Digivance 20 Watt System Indoor
Remote Unit Mounting Shelf Installation Instructions (ADCP-75-149).

WDM MOUNTING PROCEDURE (OPTIONAL ACCESSORY)
A bi-directional wavelength division multiplexer (WDM) system is available as an accessory
item for the Digivance system. If the application does not require the use of a WDM system,
skip this section and proceed to Section 4.
At the HU, the WDM system consists of a WDM host module and a WDM host module
mounting shelf. Each host module can support two HU’s and each host module mounting shelf
can hold two host modules. A fully loaded host module mounting shelf can therefore support
four HU’s.
When multiple HU’s require connection to a WDM system, the host module mounting shelf and
the HU’s should be mounted in the equipment rack as shown in Figure 3-2. This configuration
allows the pigtail leads from the two host modules to be connected directly to the optical ports
on any one of the four HU’s.

HU MOUNTING PROCEDURE
The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both
US standard and metric machine screws are included for rack mounting the HU. When loading
the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous
condition such as a severely unbalanced rack. The rack should safety support the combined
weight of all the equipment it holds. In addition, maximum recommended ambient temperature
for the HU is 50º C (122º F). Allow sufficient air circulation or space between units when the
HU is installed in a multi-rack assembly because the operating ambient temperature of the rack
environment might be greater than room ambient.
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.
Note: To insure that all optical connectors remain dust-free during installation, leave all dust
caps and dust protectors in place until directed to remove them for connection.
Use the following procedure to install the HU in the equipment rack:
1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If
mounting the HU in a 19-inch rack, proceed to step 4. If mounting the HU in a 23-inch
rack, proceed to step 2.
2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit)
and save screws for reuse.

CHASSIS GROUND CONNECTION
A stud is provided on the rear side of the chassis for connecting a grounding wire to the chassis.
Use the following procedure to connect the grounding wire to the chassis and to route the
grounding wire to an approved earth ground source.
1. Obtain a length of #18 AWG (1.00 mm) insulated stranded copper wire for use as a
chassis grounding wire.
2. Terminate one end of the wire with a ring terminal.
3. Locate the chassis ground stud at the rear of the HU as shown in Figure 3-7.
16169-A
Figure 3-7. Chassis Ground Stud
4. Attach the ring end of the wire to the chassis ground stud (see Figure 3-7).
5. Route the free end of the chassis grounding wire to an approved (per local code or
practice) earth ground source.
6. Cut the chassis grounding wire to length and connect it to the approved ground source as
required by local code or practice.
Note: Be sure to maintain reliable grounding. Pay particular attention to ground source
connections.
COAXIAL CABLE CONNECTIONS
The RF interface between the HU and the BTS is supported through two N-type female
connectors mounted on the HU front panel. One connector provides the coaxial cable
connection for the forward path (downlink) signal and the other connector provides the coaxial
cable connection for the reverse path (uplink) signal.
In most installations, it is usually necessary to insert some attenuation in the forward path link
between the HU and the BTS. A signal level that is greater than –9 dBm will overdrive and

possibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing the
forward path connection at the BTS. If the Conditioning Panel or Duplexing Panel is required,
refer to the Digivance 800 and 1900 MHz Interface Panels User Manual (ADCP-75-147) for the
installation procedures. The HU should be mounted as close as possible to the BTS to minimize
cable losses. Use the following procedure to route and connect the forward and reverse path
coaxial cables to the HU:
1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial
communications cable (RG-400 or equivalent) for all coaxial connections.
2. Route the forward and reverse path coaxial cables between the HU and the BTS interface
(per system design plan) and cut to the required length. Allow sufficient slack for dressing
and organizing cables at the HU and for installing an external attenuator in the forward
path link.
3. Terminate each cable with an N-type male connector following the connector supplier’s
recommendations.
4. Connect the forward path cable to the FORWARD RF IN connector on the HU front
panel as shown in Figure 3-8.
Note: Do not connect the forward path cable at the BTS until the composite forward path
RF signal level is measured and the amount of attenuation required is determined.

OPTICAL CONNECTIONS
The optical interface between the HU and the RU is supported by two optical ports. Each optical
port consists of an SC optical adapter which is mounted on the HU front panel. Port 1 provides
the optical fiber connection for the forward path (downlink) signal. Port 2 provides the optical
fiber connection for the reverse path (uplink) signal.
The optical connections are dependent on whether or not a WDM host module (accessory) or
CWDM host module (accessory) is installed. If the installation does not include either a WDM or
CWDM module, proceed to Section 7.1 for the optical connections procedure. If the installation
includes a WDM module, proceed to Section 7.2 for the optical connections procedure. If the
installation includes a CWDM module, refer to the Digivance System Coarse Wavelength
Division Multiplexer User Manual (ADCP-75-142) for the optical connection procedure.
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 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.
7.1
Optical Connections Without WDM or CWDM system
Use the following procedure to connect the optical fibers when a WDM or CWDM host module is
not installed with the HU:
1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber
distribution panel.
2. Designate one of the patch cords as the forward path link and the other as the reverse
path link and attach an identification label or tag next to each connector.
3. Remove the dust caps from the HU optical ports and from the patch cord connectors that
will be connected to the HU.
4. Clean each patch cord connector (follow patch cord supplier’s recommendations).
Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. After
the optical power has been measured, the attenuator may be resized or removed.
5. Insert the connector into the appropriate optical port as shown in Figure 3-9.
6. Route the patch cords from the HU to the fiber distribution panel.
Note: The HU optical adapters are angled to the left. Therefore, patch cords should always
be routed to the HU from the left side of the rack. Routing patch cords to the HU from the
right side of the rack may exceed the bend radius limitations for the optical fiber.

10. Store any excess patch cord slack at the fiber distribution panel.
7.2
Optical Connections With WDM System
Use the following procedure to connect the optical fibers when a WDM module is installed with
the HU:
1. Obtain a patch cord that is of sufficient length to reach from the WDM host module to the
fiber distribution panel.
2. Remove the dust cap from Port 1 or Port 4 on the WDM module and from the patch cord
connector that will be connected to the WDM module.
Note: Each WDM module can support two separate HU’s. The WDM module ports are
numbered from 1 through 6 as shown in Figure 3-10. Ports 1 through 3 are used for HU #1
and Ports 4 through 6 are used for HU #2.

ADCP-75-158 • Issue 1 • July 2003 • Section 4: Operation
1.2
Readiness Check
Before starting the turn-up process, inspect the complete Digivance system to verify that all
components of the system are ready to be powered-up. This will ensure that no units of the
system will be damaged during turn-up and that all existing systems will continue to function
properly.
1.2.1
Host Unit Installation Checks
Complete the following checks at the HU prior to starting the turn-up process:
1. Verify that the ON/OFF switch on the HU is in the OFF position (press O).
2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU.
3. Using a DC voltmeter, verify that the DC voltage level at the HU power terminals is
between ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The DC power provided to
the HU can be either polarity.
4. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.
1.2.2
Remote Unit Installation Checks
Complete the following checks at the RU prior to starting the turn-up process:
1. Verify that the ON/OFF switch on the STM is in the OFF position (press O).
2. Verify that the MUTE/NORM/RESET switch on the LPA in the MUTE position.
3. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power to
the RU.
4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110
and 120 VAC (for 120 VAC powered systems) or between 220 and 240 VAC (for 240 VAC
powered systems).
5. Verify that all electrical and optical connections have been completed and that all optical
fibers, coaxial cables, and wires are properly routed and secured.
TURN-UP SYSTEM AND VERIFY OPERATION
The process of turning-up the system and verifying operation involves powering up the various
system components, verifying that the LED indicators show normal operation, setting the site
number and name, adjusting the RF signal levels, and adjusting the path delay.

ADCP-75-158 • Issue 1 • July 2003 • Section 4: Operation
2.1
Turn-Up Procedure
Each Digivance system should be turned-up separately before being networked together with
multiple systems through the CAN interface. Use the following procedure to turn-up each
Digivance system:
1. Temporarily disconnect the external alarm system or notify the alarm system provider that
testing is in progress.
2. If the HU is networked together with multiple HU’s, temporarily disconnect the CAN cables
from the NET IN and NET OUT ports of each HU.
Note: By default, all HU’s and RU’s are programmed with the same site number and
name. This can cause problems for the EMS if multiple HU’s with the same site number
and site name are networked together through the CAN interface. It is therefore necessary
to temporarily disconnect the CAN interface cables from the HU when configuring the
system for operation until a unique site number and name can be assigned.
3. Determine if the forward path composite input signal level at the Host Unit FORWARD RF IN
port is appropriate for the required RF output signal level and adjust by installing an external
attenuator if necessary. Refer to Section 2.3 for the calculation and adjustment procedure.
4. Connect the EMS computer (if not already connected) to the SERVICE connector on the
HU or STM front panel. If necessary, a separate laptop computer loaded with the EMS
Version 2.0 software can be temporarily connected and used to initially configure the
system.
5. Place the ON/OFF switch on the HU in the ON position (press I).
6. Make sure the switch on the LPA is in the MUTE position and then place the ON/OFF
switch on the STM in the ON position (press I).
7. Wait 6 to 8 seconds for the HU and the RU modules to initialize and then observe the LED
indicators on the HU, STM and LPA. Refer to Section 5 for the troubleshooting
procedures if the indicators do not respond as specified.
