Figure 8 shows the T1A Status/Configuration/Loopback menu page. Real-time graphical representation
for the T1A link (using data from both the local and remote TRACER 4106/4206 units) is displayed on this
page. T1A operational configuration parameters and testing functions are configured from this menu.

>T1A STATUS/CONFIGURATION/LOOPBACK > T1A INTERFACE ALARMS
Displays any active alarms on the T1A link (reported from both the local and remote TRACER 4106/4206
units). These alarms include Red, Blue, Yellow, AIS, and bipolar violations (

Table 1. T1 Interface Alarms
RED
Activates when a local facility failure occurs.
BPV
Activates when the incoming T1 stream presents bipolar violations (BPVs).
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
Activates when no T1 signal is present from the connected T1 equipment. LOS is
activated after receiving 192 consecutive zeros.
