Transmit Receive Unit (TRU)
The Transmit Receive Unit (TRU) provides two methods for accessing the
Operation, Administration, and Maintenance (OA&M) functionality, the front
panel display interface and the AMPS/TDMA Terminal Interface. The front
panel display provides operating parameters and status information; the
Terminal Interface acts as a user-friendly interface to TRU command, control,
and monitoring functions.
The operating parameters and status information on the front panel display
are also available through the terminal interface by using the QUERY FAULT
command in the command line mode. This contains all of the necessary
information for proper OA&M functions of the TRU.
The front panel display interface
The front panel display on the TRU provides operating parameter information
for the technician to properly administer the TRU.

Figure 1-6, consists of an eight-character LED display of current status
information.
