Alarm A and Alarm B Connector Comparison
The ALARM A Connector is always functional; the ALARM B
Connector is functional when an AMR Card is equipped in the AMR 2
Slot in the SCCP Cage. Refer to Figure 3-45.
The ALARM A Port monitors Input Numbers 1 through 9 and 11
through 18, while ALARM B Port monitors Input Numbers 19 through
36. Refer to Figure 3-46.
– Alarm 10 is reserved for system use.
– State Transitions on these Input Lines are reported to the LMF and
OMC–R as MGLI Input Relay Alarms.
ALARM A and ALARM B Connectors each provide 18 Inputs and 8
Outputs.
– If both A and B are functional, 36 Inputs and 16 Outputs are
available.
– They may be configured as redundant.
– The configuration is set by the CBSC.
