MF0123A1F_FCC_uc Manual for PSR 700/800 MHz
2. Introduction
2.1. Purpose
This manual contains information and procedures for the operation of the CommScope
Public Safety Repeaters PSR 700/800 MHz 0.5/2W Class A and Class B. The purpose
of this document is to provide a step-by-step procedure to help experienced technicians
or engineers install and commission an in-building wireless enhancement system using
CommScope repeaters. Follow the instructions in this guide to minimize risks associated
with modifying a live system and preclude service interruptions. This document assumes
the technician or engineer understands the basic principles and functionality involved
with repeater and in-building systems. This guide has been written to address the
practical concerns of the installer.
2.2. PSR 700/800 MHz 0.5/2W
This pick-up repeater comes in two variants, one is a digital, channelized Class A
repeater and the second is an analogue Class B repeater. Both can be used stand-
alone or in combination with an ERA
®
system.
They are designed to cover the 700 and 800 MHz public safety bands and can be used
to establish a wireless connection between a BTS and a passive or active DAS. Via
feature keys, this repeater can be configured as a single- or dual-band version with an
output power of 0.5 W or 2 W per band. With its battery backup support (only available
in combination with a BBU/UPS), UL Type 4X housing, dry alarm contacts and its
integrated oscillation detection and healing mechanism, a fully NFPA 1221 and IFC
compliance can be guaranteed.
The implemented channel-based muting functionality prevents desensitization of the BTS
by switching off UL channels without traffic. The class A variant supports up to 32
channels in a range between 12.5 kHz and 75 kHz, where every channel can be muted
while no traffic is active. A detailed filter description can be found in table 8-1 and table
8-2. With the class B variant, the operator can choose between 3, 10 and 18 MHz pass
band bandwidths, where every pass band can be muted while no traffic is active.
