BSC control circuitry
The BSC control circuitry is the central part of the repeater, located in
the lower part of the BSC board (inside the dotted line in Figure 5-3).
The BSC control circuitry contains a microprocessor, main memory, flash
memory for the BSC software, EEPROM memory for parameters, memory
for the event log and statistics, a REFO reference oscillator, ports for local
and remote communication, battery powered real-time clock, etc.
The BSC control circuitry supervises and controls operational parameters
such as gain control, etc. The BSC control circuitry takes also care of
alarms and the event log, password, logon, and many other tasks.
The BSC control circuitry is also an interface when communicating with
an OMT32 or OMS, locally or remotely.
The BSC software can be downloaded from OMT32 or OMS either locally
or remotely.
The real-time clock in the BSC control circuitry is used for alarm and for
the event log.
BSC software
The BSC board can be run with the SA102 04 software. The board can
store two software versions, located in segment 1 and segment 2 of the
flash memory as Application 1 and Application 2. The repeater will boot
on that software which is set as Primary (a description of the Primary
application is found in the AR Repeaters and OMT32, User’s Manual.
The compatibility between the BSC board and software is detailed in the
next section.
Caution
A lithium battery is permanently mounted on the BSC board. Due to the
risk of explosion, this battery must only be removed from the board by an
authorized service technician.
