This trap indicates near end (Local) Loss of 
Multiframe Alignment, of the user E1 interface.

This trap indicates near end (Local) 
Loss of Frame Alignment (Sync Loss), caused by the reception
of AIS at the user DS1 interface.

This trap indicates AIS  being received
at the user DS1 interface.

This trap indicates that a remote loopback
has been activated, on the local uplink interface.

This trap indicates that a remote loopback 
has been activated, on the local user port.

This trap indicates that a local loopback 
has been activated on the user port.

This trap indicates that the number of Frame Slips
detected at the user DS1 interface, during the last minute
exceeds threshold. For LA-110, threshold value is 10.
This usually indicates timing problems 
(incorrect selection of timing reference) on the user DS1.

This trap indicates that the error rate 
detected on the CRC-4 bits at the
user DS1 interface, is high.

This trap indicates that the number of local
Loss of Multiframe Alignment events, detected at
the user E1 interface during the last minute exceeds threshold. 
For LA-110, threshold value is 10.

This trap indicates that the number of 
Loss of multiframe alignment events reported
by the remote unit connected to the user 
E1 interface during the last minute exceeds threshold. 
For LA-110, threshold value is 10.

This trap indicates that the number of far end 
(remote) Loss of Synchronization alarms,
reported by the user DS1 interface 
during the last minute, exceeds threshold. 
For LA-110, threshold value is 10.

This trap indicates that the far end (remote) unit, 
connected to the user E1 interface, reports
Loss of Multiframe Alignment.

This trap indicates that the number of 
Loss of local Synchronization alarms  
reported by the user DS1 interface 
during the last minute, exceeds threshold. 
For LA-110, threshold value is 10.

This trap indicates Signal Loss.
(possible reason -  cable disconnection. etc.)

This trap indicates that an Alarm Indication Signal (AIS) was detected
on an E1/T1 interface.

This trap indicates that a Loss of Frame (LOF) was detected on an E1/T1 interface.

This trap shows that a Remote Alarm Indication (RAI) was detected by an E1/T1 interface.

This trap indicates that a Loss of Multi-Frame was detected on an E1 interface.

This trap indicates that a Frame Slip occurred at the user 
DS1 interface. This usually indicates timing problems 
(incorrect selection of timing reference), 
 on the user DS1 link.

crossing alert

This trap indicates DS1 Path Severely Errored Seconds (SES)
threshold crossing alert

This trap indicates DS1 Path Severely Errored Framing
Seconds (SEFS) threshold crossing alert
