>T1X STATUS/CONFIGURATION/LOOPBACK > T1X INTERFACE ALARMS
Displays any active alarms on the T1 link (reported from both the local and remote TRACER 4208 units).
These alarms include Red, Blue/AIS, Yellow, LOS, and bipolar violations (
BPV). Table 1 breifly describes
these alarms. See Section 6, Troubleshooting Guide, for more information on these alarms.
>T1X STATUS/CONFIGURATION/LOOPBACK > T1X LINE BUILD OUT
Configures the T1 for the appropriate line buildout, based on the distance to the T1 equipment.
>T1X STATUS/CONFIGURATION/LOOPBACK > ALARM REPORTING
Determines whether the TRACER 4208 unit will report active alarms. If set to DISABLED, no alarms will be
displayed on this menu page. The
ALARM REPORTING parameter is independently configured for the local
and remote TRACER 4208 units. When set to
DISABLED, the front panel LED alarms are also disabled
(OFF).
>T1X STATUS/CONFIGURATION/LOOPBACK > SIGNALING
Configures the framing format for the T1 link for both the local and remote TRACER 4208 units. The
TRACER 4208 transports T1 data across the link (as long as the T1 signal is properly timed). Configure
the framing format (using the
SIGNALING menu) to enable the TRACER 4208 to monitor incoming framing
error events and indicate problems with the attached metallic service. The TRACER 4208 supports both
ESF and D4 framing formats.
>T1X STATUS/CONFIGURATION/LOOPBACK > LINE CODE
Sets the line coding for the T1 link. The TRACER 4208 supports B8ZS and AMI line coding.
>T1X STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE
Controls the loop status of the T1 link. Activates/deactivates loopback conditions for testing purposes.
>T1X STATUS/CONFIGURATION/LOOPBACK > LOOP/NORMAL STATE > NORMAL
Defines the T1 link as normal data transport mode - there are no active loopbacks.
Table 1. T1 Interface Alarms
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).
