>T1A STATUS/CONFIGURATION/LOOPBACK > T1A INTERFACE ALARMS
Displays any active alarms on the T1A link (reported from both the local and remote TRACER 4206
units). These alarms include Red, Blue, Yellow, AIS, and bipolar violations (
BPV). See Section 6,
Troubleshooting Guide, for more information on these alarms.
>T1A STATUS/CONFIGURATION/LOOPBACK > T1A LINE BUILD OUT
Configures the T1A for the appropriate line buildout, based on the distance to the T1A equipment.
>T1A STATUS/CONFIGURATION/LOOPBACK > ALARM REPORTING
Determines whether the TRACER 4206 unit will report active alarms. If DISABLED, no alarms will be
displayed on this menu page. The ALARM REPORTING parameter is independently configured for the local
and remote TRACER 4206 units. When DISABLED, the front panel LED alarms will also be disabled (OFF).
>T1A STATUS/CONFIGURATION/LOOPBACK > SIGNALING
Configures the framing format for the T1A link for both the local and remote TRACER 4206 units. The
TRACER 4206 transports T1A data across the link (as long as the T1A signal is properly timed).
Configure the framing format (using the SIGNALING menu) to enable the TRACER 4206 to monitor
incoming framing error events and indicate problems with the attached metallic service. The TRACER
4206 supports both
ESF and D4 framing formats.
>T1A STATUS/CONFIGURATION/LOOPBACK > LINE CODE
Sets the line coding for the T1A link. The TRACER 4206 supports B8ZS and AMI line coding.
>T1A STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE
Controls the loop status of the T1A link. Activates/deactivates loopback conditions for testing purposes.
>T1A STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE > NORMAL
The T1A link is in normal data transport mode - there are no active loopbacks.
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.
