Set alarm options (Part 2 of 2)

Option	Description
AL2 Threshold	Sets the allowable bit errors per second (from 3 to
	9) before alarm level 2 is activated. Factory
	default is 10-5.
AL2 Duration	Sets the duration in seconds (from 1 to 3,600
	seconds) that alarm level 2 is activated. Factory
	default is 10 seconds.
Frame Slip	Sets the allowable frame slips per time period
Threshold	(from 1 to 255) before alarm level 2 is activated.
	Factory default is 5.
Frame Slip Duration	Sets the duration in hours (from 1 to 24) that the
	frame slips are counted. After this time period, the
	counter is reset to 0. Factory default is 2 hours.

Note: If the duration period set is too long, the LEI card is slow to return to service automatically even when the carrier is no longer experiencing errors. The CLEAR ALARM (C A) command has to be entered manually to restore service promptly. To avoid this, an alarm’s duration period is normally set to 10 seconds.

Set Clearing

The SET CLEARING (S C) command allows self-clearing of alarms by responding to the question: Enable Self Clearing? (YES or NO). If YES is chosen (the factory default setting), the system automatically clears (resets) alarms after the alarm condition is no longer detected. Choosing the NO option causes the system to continue the alarm condition until the Clear Alarm (C A) command is entered. Line processing and yellow alarm indication to the CPE terminates as soon as the alarm condition clears, even if self-clearing is disabled.

Set Simple

The SET SIMPLE command controls call tear-down signaling when the far-end disconnects from a call.
