X TATUS ONFIGURATION
Displays any active alarms on the E1 link (reported from both the local and remote TRACER units).
These alarms include AIS, CRC, LCV, LOS, OOF, and RMT. Table 1 briefly describes these alarms. See
Section 6, Troubleshooting Guide, on page 119, for more information on these alarms.
AIS (Alarm Indication Signal) Activates when an incoming remote alarm is received from a
connected E1 device. An AIS signal is an unframed all one signal that replaces the normal
traffic signal.
CRC (Loss of CRC-4 Framing) The receiver is unable to synchronize to the CRC-4 frame
pattern of the received signal.
LCV (Line Code Violations) Activates when the incoming E1 stream presents line coding
violations.
LOS (Loss of Signal) Activates when no E1 signal is present from the connected E1 equipment.
LOS is activated after receiving 192 consecutive zeros.
OOF (Out of Frame) The receiver is unable to synchronize to the FAS framing pattern of the
received signal.
RMT (Received Remote Alarm) Activates when an incoming remote alarm is received from the
E1 device, indicating that a failure has occurred in the received direction.

Configures the framing format for the E1 link. The TRACER transports E1 data across the link (as long as
the E1 signal is properly timed). Configure the framing format (using the
TRACER to monitor incoming framing error events and indicate problems with the attached metallic
service. The TRACER supports
framing sequence bits), and
