Displays any active alarms on the E1 link (reported from both the local and remote TRACER 64x0 units). 
These alarms include AIS, CRC, LCV, LOS, OOF, and RMT. Table 1 briefly describes these alarms. See 
Section 8, Troubleshooting Guide, on page 123 for more information on these alarms.

(Read Only) Displays the current interface type of the E1 module as either 

 or 

.

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, the 

 port, alarm contacts, menu screens, or LEDs on the front panel. By default, alarm 

reporting is set to 

.

When 

, the receiver detects the CRC-4 checksum bits in the outgoing E1 data stream and checks 

the received signal for errors.

Configures the framing format for the E1 link. The TRACER 64x0 transports E1 data across the link (as 
long as the E1 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 

 (also known as CAS), 

 (all 

data stream with no framing sequence bits), and 

 (also known as CCS). The default value is 

.

(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.

(Loss of CRC-4 Framing) The receiver is unable to synchronize to the CRC-4 frame 
pattern of the received signal.

(Line Code Violations) Activates when the incoming E1 stream presents line coding 
violations.

(Loss of Signal) Activates when no E1 signal is present from the connected E1 equipment. 
LOS is activated after receiving 192 consecutive zeros.

(Out of Frame) The receiver is unable to synchronize to the FAS framing pattern of the 
received signal.

(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.
