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
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.
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.
Caution: This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot
(91.4 cm) minimum clearance from the antenna while the system is operating. Wherever
possible, shut down the RAN before servicing the antenna.
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails
without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent
or curved to a radius of less than 2 inches (5.1 cm).
Caution: Exterior surfaces of the RAN may be hot. Use caution during servicing.

SAFE WORKING DISTANCES
The Digivance NXD antenna, which is mounted on top of a pole, radiates radio frequency
energy.
For the occupational worker, safe working distance from the antenna depends on the workers
location with respect to the antenna and the number of wireless service providers being serviced
by that antenna.
Emission limits are from OET Bulletin 65 Edition 97-01, Table 1 A.

PRODUCT DESCRIPTION
This section describes the Digivance Neutral Host (NXD) Radio Access Node (RAN).
1.1
General Description
The RAN, shown in Figure 1, is the remote component in the Digivance NXD Multi-Band
Distributed Antenna System. The RAN is a pole-mounted or pad-mounted, weather-resistent
cabinet, housing electronic modules that operate on an internal cPCI backplane. Included are a
central processing unit, a system interface, an optical interface, optical to RF data converters,
RF multicouplers, and DC power supplies. The RAN also houses rectifiers, backup batteries,
power amplifiers, and optical wave division multiplexers. Optical and RF functions are both
required because the RAN exchanges data with the system Hub using an optical link and
exchanges data with wireless users using RF signals. Each RAN provides the system with an RF
antenna and can accommodate up to four bands (PCS A-F, SMR A, Cell A”/A, or Cell B/B’). Dual
RANs installed at the same location can accommodate up to eight bands using a common
antenna.

1.2
System Function
The NXD Distributed Antenna System (DAS), in which the RAN is the remote component, is a
multi-frequency, multi-protocol RF access network providing microcellular Cellular and PCS
coverage via a distributed RF access system. In a typical configuration, such as shown in
Figure 2, multiple RANs are connected to a central Hub where multiple Base Transceiver
Station (BTS) interfaces are located. Signals received at the Hub are distributed to the RANs in
digital form by way of a fiber optical link. Within the RANs, the signals are converted from
digital to RF format to be transmitted from the RAN antennas. Signals also travel in a reverse
direction, from the RANs to the Hub, with a reverse data conversion.
Physically, the DAS consists primarily of electronic modules located in the Hub and RANs. At
the Hub, these modules are mounted in an equipment rack typically housed in a common
telecommunications structure with the base station electronics for Wireless Service Providers
(WSPs), either in the same room or nearby. These modules include high power attenuators, base
station modules, a power distribution unit, an Ethernet hub, a Hub reference module, an RF
chassis, and one or more digital chassis. The RAN electronic modules, mounted in the RAN
cabinet, perform the remote system functions of optical to RF data conversion and RF access.
These modules are described in subsequent topics within this product description. Digivance
Element Management System (EMS) software, running on a computer located at the Hub,
provides a graphical user interface to monitor system performance.

High-Level View
The RAN consists of the main components shown in a high-level view in Figure 3. These
components include:
• RAN Cabinet: exterior shell of the RAN containing cable connection points, ground
studs, and slots or shelves supporting other RAN components.
• RAN Chassis: standard Compact PCI (cPCI) shelf capable of housing 21 industry
standard cPCI circuit card modules. The modules are plugged into a common backplane
providing data bussing between them.
• Related Electronics: including rectifiers, Power Amplifier Assemblies (PAAs), batteries,
multiplexers, and a circuit breaker panel.
All components called out in the figure except for the multiplexers are separately installable in
the field. In most cases, however, the RAN is shipped with a basic set of components having
been ordered in advance by the customer and installed in the factory.

RAN Cabinet
The RAN cabinet is a NEMA-3R enclosure designed to protect its electronic components from
weather and human tampering. The cabinet is weather-tight but contact with salt-air mist should
be avoided as it may decrease the mean time between failure of some components. The cabinet
has ventilation openings to allow entry of cool air and escape of hot air. The cabinet provides
termination points for the coaxial antenna cable, fiber optic cable, ground cable, and AC cable.
The cabinet has inbuilt AC power surge protection and limited storage for fiber optic cables.
1.6.1
Mounting
The RAN cabinet may be mounted on a wood pole or on a concrete pad. Mounting bracket kits
(available from ADC) are required for each type of installation.
