Configuring the System Traffic Card (STC)
Configuring the System Traffic Card (STC)
The system can have either one or two STC cards. A second card is used to improve
system reliability. If a fault occurs in the STC card that has command of the system, the
operation will revert to the secondary STC, and system operation will not be affected.
Both STC cards should be configured identically.
STC Switches
Two sets of switches are used to set the data rate and default function of the four service
ports accessible on the back of the unit.
The eight Data Rate switches are divided into four pairs labeled “L” (Logger), “C”
(Clock), “M” (Modem/Service), and “R” (Radio Management). Each of these ports can be
set to one of four data rates.
The six Mode switches specify the default power-up and reset functions of the Logger,
Modem, and Radio Management ports. Backplane monitor (service) information, radio
system management information, and general logging information may be directed to any
of these ports by setting the associated pair of switches.
For each pair, data is directed to the ports according to the following table:
Switch Function
F Backplane Monitor Destination
E Backplane Monitor Destination
D Radio System Management Report Destination
C Radio System Management Report Destination
B Logger Data Destination
A Logger Data Destination
Note In order to activate backplane monitoring, you must log into the
STC via one of the backplane ports and set up the appropriate
parameters.
