LARMS
Displays any active alarms on the T1 link (reported from both the local and remote TRACER 6420 units). 
These alarms include Red, Blue/AIS, Yellow, LOS, and bipolar violations (BPV). Table 1 briefly 
describes these alarms. See Section 8, Troubleshooting Guide, for more information on these alarms.
The following menus for the T1x Status/Configuration/Loopback apply to all four 
available T1 interfaces (A through D).
Table 1.  T1 Interface Alarms 
RED
Activates when no T1 signal is present from the connected T1 equipment. LOS is 
activated after receiving 192 consecutive zeros.
BLUE/AIS
Activates when an incoming remote alarm is received from a connected T1 device. An AIS 
signal is an unframed All One signal that replaces the normal traffic signal.
YEL
Activates when an incoming remote alarm is received from the T1 device indicating that a 
failure has occurred in the received direction.
LOS
Loss of sync occurs when the TRACER system cannot synchronize to the incoming T1 
data stream.
BPV
Activates when the incoming T1 stream presents BPVs.
