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/DCRH 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 1.5 inches (38 mm).
STANDARDS CERTIFICATION
FCC: This equipment complies with the applicable sections of Title 47 CFR Parts 15, 22, 24, and
90.
UL/CUL: This equipment complies with UL and CUL 1950 Standard for Safety for
Information Technology Equipment, Including Electrical Business Equipment.
FDA/CDRH: This equipment uses a Class 1 LASER according to FDA/CDRH Rules. This
product conforms to all applicable standards of 21 CFR Part 1040.

1 SYSTEM FUNCTIONAL OVERVIEW AND UNIT DESCRIPTION
This section provides an overview of the Digivance Indoor Coverage Solution (ICS), a
description of the functions and features provided by the units that comprise the system, a
listing of terms used and their definition, and a table of specifications.
1.1 System Functional Overview
The Digivance ICS is a digitally distributed antenna system that provides in-building coverage
for analog (AMPS) or digital (TDMA or CDMA) cellular phone systems operating within the
800 MHz frequency band. 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 cellular
communications within buildings or structures difficult or impossible. With the Digivance
ICS, cellular phone RF signals can be distributed to the interior areas of any building or
structure to eliminate dead spots and improve reception.
ADCP-75-110 • Issue B • March 2001
1.1.1 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, two accessory items, the Local Interface Unit (LIU) and the Remote Interface Unit
(RIU) may be used as needed to interface the DHU with the cellular system Base Transceiver
Station (BTS).
1.1.2 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
(microcell) is co-located with the DHU, a local interface over coaxial cable is possible. An
interface device, such as the LIU, may be required to provide the proper input and output RF
signal levels between the BTS and the DHU. When the BTS (cell site base station) is not colocated with the DHU, a remote interface using a donor antenna is required. An interface
device such as the RIU is required to provide the proper input and output RF signal levels
between the donor antenna and the DHU.
The DHU interfaces, as described in the preceding paragraph, with the BTS. 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 DEUs and DRUs. In the reverse
path, the DHU receives digital optical signals from the DRUs and DEUs. The DHU converts
the optical signals back to the original RF signal format for transmission to the BTS.

1.1.3 Interface With Cellular Phones
The DRUs interface 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 antenna is connected to the DRU to
transmit and receive RF signals from the cellular phones.
