Displays any active alarms on the T1 link (reported from both the local and remote TRACER 64x0 units). 
These alarms include Red, Blue/AIS, Yellow, LOS, and bipolar violations (BPV). Table 2 briefly 
describes these alarms. See Section 8, Troubleshooting Guide, on page 125 for more information on these 
alarms.

Determines whether the TRACER 64x0 unit will report active alarms. If set to 

, no alarms will be 

displayed on this menu page. The 

 parameter is independently configured for the local 

and remote TRACER 64x0 units. When set to 

, the TRACER 64x0 does not report active alarms 

via SNMP or the 

 port, and the status LEDs are off. By default, alarm reporting is set to 

.

Configures the T1 for the appropriate line build out, based on the distance to the T1 equipment. By default, 
the line build out for the TRACER 64x0 is 

.

Configures the framing format for the T1 link for both the local and remote TRACER 64x0 units. The 
TRACER 64x0 transports T1 data across the link (as long as the T1 signal is properly timed). Configure 
the framing format (using the 

 menu) to enable the TRACER 64x0 to monitor incoming framing 

error events and indicate problems with the attached metallic service. The TRACER 64x0 supports both 
extended superframe (

) and superframe (

) framing formats. By default, the signaling method is set 

to 

.

Sets the line coding for the T1 link. The TRACER 64x0 supports bipolar eight-zero substitution (

and alternate mark inversion (

) line coding. By default, the line code is set to 

.

Controls the loop status of the T1 link. Activates/deactivates loopback conditions for testing purposes.

Activates when no T1 signal is present from the connected T1 equipment. LOS is 
activated after receiving 192 consecutive zeros.

(Alarm Indication Signal) 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.

(Yellow Alarm) Activates when an incoming remote alarm is received from the T1 device 
indicating that a failure has occurred in the received direction.

(Loss of Sync) Occurs when the TRACER system cannot synchronize to the incoming T1 
data stream.

(Bipolar Violations) Activates when the incoming T1 stream presents BPVs. BPVs occur 
when two one bits are received back-to-back with the same polarity.
