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.
When the far-end terminates a call, Release 1 of LEI's AB vintage sends a
disconnect message to the terminal equipment and waits for the terminal
equipment to go idle before going idle itself. A NO response to the S S
command configures Release 2 (and later) boards to operate in this way.
See
Release 2 of AB vintage LEIs gives the administrator the option of using
the signaling described above, or configuring the LEI to take its channel idle
immediately after sending the call-disconnect message. A YES response
to the S S command, the default configuration for Release 2 (and later)
boards, configures the LEI to operate in this way. See

Description
Sets the allowable frame slips per time period (from 1 to 255)
before alarm level 2 is activated. Factory default is 5.
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.
