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
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 transceiver 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 transceiver 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: 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.

INTRODUCTION
This section provides basic description, application, and configuration information about the
Digivance 1900 MHz 20 Watt System. Throughout this publication, all items referenced as
“accessory items” are not furnished with the basic product and must be purchased separately.
1900 MHZ 20 WATT SYSTEM OVERVIEW
The Digivance 1900 MHz 20 Watt System is an RF signal transport system that provides longrange RF coverage in areas where it is impractical to place a Base Transceiver Station (BTS) at
the antenna site. High real estate costs and community restrictions on tower and equipment
locations often make it difficult to install the BTS at the same location as the antenna. The
Digivance system is designed to overcome equipment placement problems by allowing base
stations to be hubbed at a central location while placing remote antennas at optimum locations
with minimal real estate requirements. With the Digivance system, RF signals can be
transported to one or more remote locations to expand coverage into areas not receiving service
or to extend coverage into difficult to reach areas such as canyons, tunnels, or underground
roadways.
2.1
Basic System Components
The basic components of a Digivance 20 Watt System and their functions are shown in
Figure 1-1. A 20 Watt system consists of the Host Unit (HU) and the Remote Unit (RU). Both
an indoor and an outdoor remote unit are available. Control and monitoring functions are
provided by the Digivance Element Management System (EMS), a PC-based software program.
In addition, various accessory items are available separately including a passive Wavelength
Division Multiplexer (WDM) system, an active Coarse Wavelength Division Multiplexer
(CWDM) system, conditioning and duplexing panels (for interfacing the HU with the BTS),

Base Transceiver Station to Host Unit Interface
The HU interfaces with the BTS which provides the RF channel inputs and outputs for a
designated sector. The BTS/HU interface may require installation of the Digivance Interface
Panels which are accessory products for the Digivance system. The Interface Panels are used
when multiple BTS’s and multiple Host Units require connection or when RF attenuation is
needed between the BTS and Host Unit.
Two types of Interface Panels are available: the Conditioning Panel and the Duplexing Panel. The
Conditioning Panel provides attenuation of the forward path signal to the level required for input
to the Host Unit. The Conditioning Panel also provides forward and reverse path combining and
splitting (as needed) to enable multi-BTS to single Host Unit, multi-BTS to multi-Host Unit, or
single BTS to multi-Host Unit configurations. A typical single BTS to multi-Host Unit
configuration is shown in Figure 1-2.

The Duplexing Panel is used in conjunction with the Conditioning Panel when the BTS
provides a duplexed forward and reverse path RF connection as shown in Figure 1-3. The
Duplexing Panel separates the duplexed forward and reverse path signals. This allows the BTS
to be connected to the Host Unit which has separate forward and reverse path RF ports.

Handset Interface
The RU interfaces with the handsets (cell phones) through an antenna. In the reverse path, the
RU receives RF signals from each handset. The RU digitizes the RF signals and then converts
them to digital optical signals for transport to the HU over the fiber optic link. In the forward
path, the RU receives digital optical signals from the HU. The RU converts the optical signals to
RF signals for transmission to the handsets. The RU is connected to an antenna (not provided)
which transmits and receives the handset RF signals.
2.4
Local Service Interface
Local communications with an individual Digivance system is supported through a local service
interface capability as shown in Figure 4. The primary component of the local interface is a PCtype laptop computer loaded with the Digivance Element Management System (EMS) software.
The EMS provides the various control and monitoring functions required for local management
of each Digivance system. The EMS computer can be directly connected to either the HU or RU
through the computer’s RS-232 port. Operation is done through the EMS Graphical User
Interface (GUI). The GUI consists of a series of screens from which the user selects the desired
option or function. An RS-232 service port is provided on both the HU and the RU for
connecting the EMS computer.

Remote NOC Interface
Remote communications between a Network Operations Center (NOC) and a networked
grouping of multiple Digivance systems is supported by a remote NOC interface capability as
shown in Figure 1-5. The primary component of the remote NOC interface is a PC-type desktop
computer loaded with the Digivance Element Management System (EMS) software. EMS
provides the various control and monitoring functions required for remote management 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’s
can be networked together in daisy-chain fashion and controlled though the same EMS
computer. The EMS computer connects to the networked HU’s through the computer’s RS-232
port #1. All HU’s can then be controlled through the same EMS computer.
The NOC is connected to the EMS computer through a T1 system or other medium. The EMS
computer’s RS-232 port #2 interfaces with the T1 system equipment. The T1 equipment must
be capable of interfacing with an RS-232 ASCII interface port.
At the NOC, control and monitoring of the networked Digivance systems are effected through a
Network Element Manager (NEM) interface which requires only a VT100 terminal/emulator
for operation. The NEM interface language consists of simple ASCII text strings. All
communications are input as either SET or GET commands which result in ASCII text string
responses from the specified system or systems. The EMS desktop computer may also be used
locally to manage the networked Digivance systems. Local operation is through the EMS
software GUI.

SYSTEM FUNCTIONS AND FEATURES
This section describes various system level functions and features of the Digivance System.
3.1
Fiber Optic Transport
In a typical Digivance 20 Watt system with a single HU and RU, the HU is connected to the RU
over a pair of single-mode 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, the input and output RF signal levels at the HU or the RU are not dependent on
the level of the optical signal or the length of the optical fiber. A diagram of the fiber optic
transport system for a typical Digivance system is shown in Figure 1-6. The Digivance 20 Watt
system does not support reverse path diversity at this time.
The maximum length of the optical fibers is dependent on the loss specifications of the optical
fiber and the losses imposed by the various connectors and splices. The system provides an
optical budget of 25 dB (typical) when used with 9/125 single-mode fiber.

In some applications, it may be desirable or necessary to combine the forward path and reverse
path optical signals from a single HU/RU pair onto a single optical fiber. This can be
accomplished 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 path
and 1310 nm for the reverse path. Because the Digivance system uses different optical
wavelengths for the forward and reverse paths, both signals can be combined on a single optical
fiber. One WDM module is mounted with the HU and the other WDM module is mounted with
the RU as shown in Figure 1-7. The WDM system is available as an accessory item.

In some applications, it may be desirable or necessary to combine the forward and reverse path
optical signals from multiple HU’s and RU’s onto a single optical fiber. This can be
accomplished by using an active Coarse Wavelength Division Multiplexer (CWDM) system. Up
to four Digivance systems may be configured to operate over a single optical fiber. A CWDM
module is mounted with each HU and RU as shown in Figure 1-8. The CWDM system converts
the optical signal transmitted by each HU and RU to a new optical wavelength that is unique for
each unit. This allows the CWDM system to distinguish between the optical signals generated
by each HU and RU and therefore to distribute those signals to the appropriate destination. The
CWDM system is available separately as an accessory item.

A Free Space Optics (FSO) system (that meets the Digivance system data rate performance and
BER requirements) may be used in applications where it is desirable or necessary to bridge an
open span and where it is impractical to lay a fiber optic cable. One FSO transceiver unit may be
mounted on the HU side of the open span and the other FSO transceiver unit may be mounted
on the RU side of the open span. A system diagram of an FSO application is shown in
Figure 1-9. FSO systems are available from various equipment manufacturers.

Control and Monitoring Software
The Digivance EMS software supports control and monitoring functions for both the local and
remote service interfaces. The EMS software is stored on a CD-ROM which is included with the
EMS software package. Software installation consists of copying the software files from the
CD-ROM to a designated directory on the hard-drive of the EMS computer.
The EMS software is used to provision and configure the Digivance system for operation. This
includes selecting a sitename, setting alarm thresholds, and setting forward and reverse path RF
gain adjustments. The EMS software is also used to get alarm messages (individual or
summary), data measurements, or to upgrade the HU/RU system software. All control and
monitor functions (except software upgrade which can only be done using the EMS software
GUI) can be effected using either the NOC/NEM interface or the EMS software GUI.
3.3
Fault Detection and Alarm Reporting
LED indicators are provided on the front panel of the HU and on the front panels of the RU
modules 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 HU
for connection to a customer-provided external alarm system. All alarms can also be accessed
through the NOC/NEM interface or the EMS software GUI.
3.4
Powering
The HU is powered by ±24 or ±48 VDC and must be hard-wired to a local office battery power
source through a fuse panel. A screw-down terminal strip is provided on the rear side of the HU
for the power connections.
The RU is powered by 120 or 240 VAC (50 or 60 Hz) and must be connected to an AC power
source through a 20 Amp breaker box. A three-wire cable is provided for the AC power
connections. A 120 VAC outlet should be installed near the RU for powering test equipment or
power tools. In certain applications, it may be necessary to install a surge protector (not
provided) in the AC power feed to prevent equipment damage from AC power spikes.
3.5
Equipment Mounting and Configuration
The HU is designed for mounting in a non-condensing indoor environment such as inside a
wiring closet or within an environmentally-controlled cabinet. The HU is intended for rackmount applications and may mounted in either a 19- or 23-inch WECO or EIA equipment rack,
usually within 20 feet of the BTS.
The outdoor RU is designed for mounting in an outdoor environment. The outdoor RU consists
of a Spectrum Transport Module (STM), a Linear Power Amplifier (LPA) module, and a selfcontained 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 may
degrade the MTBF of the product. The outdoor cabinet can be mounted from a flat-vertical
surface, from a utility pole (requires pole-mount kit), or mounted on a pedestal (requires

pedestal kit). Slots are provided within the cabinet for the STM and LPA modules. Storage
spools are provided for storing short lengths of excess fiber slack. A mounting slot is also
provided for a WDM or CWDM remote module (accessory items). A lighting protector for the
antenna is included with the outdoor cabinet to prevent equipment damage from lighting strikes.
The indoor RU is designed for mounting in a non-condensing indoor environment such as
inside a wiring closet or within an environmentally-controlled cabinet. The indoor RU is
intended for rack-mount applications and may be mounted in either a 19- or 23-inch WECO or
EIA equipment rack. The indoor RU consists of a Spectrum Transport Module (STM), a Linear
Power Amplifier (LPA) module, and a mounting shelf that supports the modular components.
The mounting shelf installs in the equipment rack. Slots are provided in the mounting shelf for
the STM and LPA modules. Slots are also provided for mounting the WDM or CWDM remote
module (accessory items).

INTRODUCTION
This section describes the basic components of the Digivance 1900 MHz 20 Watt system
including the Host Unit (HU), the Remote Unit (RU), and the Digivance Element Management
System (EMS). Also described are various accessory items including the InterFace Panels,
Wavelength Division Multiplexer (WDM) system, and Coarse Wavelength Division Multiplexer
(CWDM) system. The RU is an assembly that consists of a cabinet (for outdoor applications) or
mounting shelf (for indoor applications), a Spectrum Transport Module (STM), and a Linear
Power Amplifier (LPA) module. For clarity, the various components that comprise the RU are
described separately.
HOST UNIT
The HU, shown in Figure 2-1, serves as the BTS servicing unit for the Digivance system. The
HU provides the following basic functions:
• Provides a gain adjustable RF interface with the BTS.
• 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 Components
The HU consists of an electronic circuit board assembly and a fan assembly that are mounted
within a powder-paint coated sheet metal enclosure. The enclosure provides a mounting point
for the circuit board and fan assemblies and controls RF emissions. The only user-replaceable
component is the fan assembly. The HU is designed for use within a non-condensing indoor
environment such as inside a wiring closet or cabinet. All controls, connectors, and indicators
(except the power terminal strip) are mounted on the HU front panel for convenient access.
Cable management functions for the coaxial cables and copper wiring are provided by a cable
management tray that extends outward from the HU front panel.
2.2
Mounting
The HU is intended for rack-mount applications. A pair of reversible mounting brackets is
provided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECO
equipment rack. When installed, the front panel of the HU is flush with the front of the rack.
The cable management tray extends 3.9 inches (99 mm) beyond the front panel. Fasteners are
provided for securing the HU to the equipment rack.

Fault Detection and Alarm Reporting
The 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 turn
from green to red or yellow if a fault is detected. A set of alarm contacts (normally open and
normally closed) are provided for reporting an alarm to an external alarm system when a fault is
detected. Both major alarm (system operation seriously affected) and minor alarm (system
operation not affected or only slightly degraded) contacts are provided.
The status of the HU, the alarm state (major or minor), and other alarm information is
summarized and reported over the service interface, the CAN interface, and also over the optical
interface to the RU. In addition, the state of the RU is received over the optical fiber and reported
over the service interface and the CAN interface. This detailed information may be accessed
remotely through the NOC/NEM interface or locally through the EMS software GUI.
2.4
RF Signal Connections
The RF signal connections between the HU and the BTS are supported through two N-type
female connectors. One connector is used for the forward path RF signal. The other connector is
used for the reverse path RF signal. The current 20 Watt system does not support a diversity
reverse path. In most installations, it is usually necessary to install a Conditioning Panel and/or
Duplexing Panel (accessory items) to support the interface between the HU and the BTS. The
HU should be as close as possible to the BTS to minimize cable losses.
2.5
RF Signal Level Adjustments
The HU is equipped with several attenuators for adjusting the signal levels of the forward and
reverse path RF signals. The attenuators provide an attenuation adjustment range of 0 to 31 dB
and can be set in 1 dB increments. The attenuators are software controlled and are adjusted
through the NOC/NEM interface or the EMS software GUI.
Page 2-4
© 2003, ADC Telecommunications, Inc.
ADCP-75-158 • Preliminary Issue A • June 2003 • Section 2: Description
The host forward path attenuator adjusts the level of the input RF signal to the HU. Using the
forward path attenuator, an input signal with a nominal composite signal level of –9 dBm to –40
dBm can be adjusted to produce maximum power output. Additional external attenuation is
required if the input signal level is greater than –9 dBm.
The host reverse path attenuator adjusts the level of the output RF signal and will add from
–1 dB of gain (attenuator set to 31 dB) to +30 dB of gain (attenuator set to 0 dB) to the RF
output signal at the HU.
2.6
Propagation Delay
The HU forward and reverse path propagation delays may be adjusted in 0.1 µsec increments
within a range of 0 to 63 µs. The propagation delay is software controlled and may be adjusted
through the NOC/NEM interface or the EMS software GUI.
2.7
Optical Connection
Optical connections between the HU and the RU (STM) are supported through two SC-type
optical connector ports. One port is used for connecting the forward path optical signal and the
other port is used for connecting the primary reverse path optical signal.
2.8
Controller Area Network Interface Connection
Controller Area Network (CAN) interface connections between multiple HUs are supported by
a pair of RJ-45 jacks. One of the jacks is designated as the network IN port and the other jack is
designated as the network OUT port. The CAN interface allows up to 24 HUs to be connected
together (in daisy-chain fashion) and controlled through a single Digivance EMS computer.
2.9
Service Interface Connection
The service interface connection between the HU and the Digivance EMS computer is
supported by a single DB-9 female connector. The service connector provides an RS-232 DTE
interface. When multiple HUs are networked together, the supporting EMS computer may be
connected to the service connector of any one of the networked HUs.
2.10 Powering
The HU is powered by ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The power is fed to
the HU through a screw-down type terminal strip located on the rear side of the unit. Power to
the HU must be supplied through a fuse panel such as the 20 position PowerWorx Fuse Panel
(accessory item). The power circuit for each HU must be protected with a 3 Amp GMT fuse. An
On/Off switch is provided on the HU front panel.

3.1
Primary Components
The RU outdoor cabinet consists of the enclosure, mounting slots for the STM and LPA modules,
connectors and a wiring harness for interfacing the STM and LPA modules, a mounting slot for
either the WDM or CWDM module (accessory items), lightning protector, and two fiber storage
spools. The RU outdoor cabinet is designed for use in an outdoor environment. Opening the
hinged door provides full height and width access to the interior of the enclosure to facilitate
module and cable installation.
The enclosure is constructed of heavy gauge aluminum and is painted putty white for corrosion
protection. Connection and/or entry points are provided in the bottom of the enclosure for the
antenna coaxial cable, fiber optic cable, and AC power cable. Vent openings are provided in the
bottom of the enclosure to permit air exchange for cooling. The RU cabinet is weather-tight but
contact with salt-air mist should be avoided as it may degrade the Mean Time Between Failure
(MTBF) of the product. Drain holes in the bottom of the cabinet allow any moisture that does
enter the cabinet to drain out. The cabinet door is equipped with a sturdy latch so that the
enclosure may be padlocked to prevent unauthorized entry. A door open switch is provided so
that a major alarm is generated whenever the cabinet door is opened.

3.2
Mounting
The RU cabinet may be mounted on a flat vertical surface (such as the side of building) on a
utility pole, or on a pedestal. A special mounting bracket is provided with each enclosure.
Installation consists of securing the bracket to the mounting surface and then hanging the
enclosure from the bracket. The mounting 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 pole-mount kit (accessory item) is available for mounting the
cabinet from a utility pole. A pedestal-mounting kit (accessory item) is available for mounting
the cabinet on a flat horizontal surface.
3.3
STM and LPA Module Installation
Two mounting slots are provided within the RU cabinet for installing the STM and LPA
modules. The mounting slots include tracks that guide each module into the installed position.
Separate mounting slots are provided for STM and LPA modules. Two D-sub connectors (one
male, one female) are located at the rear of each mounting slot. Each mounting slot connector
mates with a corresponding D-sub connector located on the rear side of each module. A wiring
harness links the mounting slot connectors together. The connectors and the attached wiring
harness provide the electrical interface between the STM and LPA modules. The modules are
held in the installed position with captive screws.
3.4
WDM and CWDM Installation
A mounting slot is provided within the RU cabinet for installing a WDM or CWDM remote
module (accessory items). Each module is equipped with push-pull type fasteners for securing
the module to the mounting slot. A power cable is included with the cabinet for providing power
when a CWDM module is installed. Fiber storage spools are provided for storing excess pigtail
and/or patch cord slack.
3.5
Fiber Optic Cable Entry
A plastic cord connector is provided in the exterior bottom side of the RU cabinet for routing a
fiber optic cable into the enclosure. The cord connector provides cable strain relief and a
watertight seal at the fiber optic cable entry point. As the connector nut is tightened, a soft
neoprene bushing compresses to tightly grip the cable without applying excessive force to the
fibers. The cord connector can accommodate cables that range from 0.375 to 0.875 inches (10 to
23 mm) in diameter. A spool is provided directly above the fiber optic cable entry hole for
storing excess pigtail slack.
In a typical installation, the connectorized end of a mulit-fiber outside plant cable is routed into
the enclosure through the cord connector and the individual fibers are broken out into pigtails.
The pigtails are connected to the optical ports on the STM and the excess pigtail slack is stored
on the fiber storage spool. The stub end of the cable is routed to an external splice enclosure (not
provided) for splicing to the fiber optic cable.
