Figure 8 shows the T1x Status/Configuration/Loopback menu page, which displays a real-time graphical
representation for the T1x link using data from both the local and remote TRACER 4106/4206 units. T1x
operational configuration parameters and testing functions are configured from this menu.

>T1X STATUS/CONFIGURATION/LOOPBACK > T1X INTERFACE ALARMS
Displays any active alarms on the T1 link (reported from both the local and remote TRACER 4106/4206
units). These alarms include Red, Blue/AIS, Yellow, LOS, and bipolar violations (
BPV). Table 2 briefly
describes these alarms. See Section 6, 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).

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