Tracer SYSTEM CONFIGURATION
A Tracer system is composed of three major subsystems -- a
baseband processor, a radio frequency convertor, and an antenna.
The following section describes the system components.
BASEBAND PROCESSOR OR BBP
The BBP (ADTRAN part number 1280.003L1) is a 1-U, 19" rack-
mountable unit that provides the system electrical interfaces, user
controls and indicators, and performs the spread spectrum
processing for the system. The rear panel provides all of the
electrical interface points -- DS1/DSX-1 interface, DS1/DSX-1
monitor, VT-100 terminal, alarm contacts, IF signal, DC power
(from facility), and power (from AC adapter). The BBP and its
rear panel are illustrated in the figures below.
