Table 98: Set alarm options
Option
Description
AL1 Threshold
Sets the allowable bit errors per second before alarm level 1 is activated.
Factory default is 6.
AL1 Duration
Sets the duration in seconds (from 1 to 3,600 seconds) that alarm level
1 is activated. Factory default is 10 seconds.
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
Threshold
Sets the allowable frame slips per time period (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.
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
Figure 53: Set Simple (S S) no screen
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-
