<param> Legal <value>s ISiCL “SET” Parameter Description
Module Redundancy Switches
MRDN NRVRT, RVRT,
OFF
RVRT - Revertive module switching. Switches to backup module
upon failure of primary module and then switches back to primary
if the failure condition is cleared or if the backup module has
failed.
NRVRT - Non-revertive module switching. Switches to backup
module upon failure of primary module and then switches back to
the primary if the backup module has failed.
OFF - Never switch modules due to module failure.
MLINE SAME, DIFF SAME – The same type of T1 facility exists for both primary and
backup lines. When in SAME redundancy mode, a failure of the
primary common module (CM) results in a module switch only.
Service remains on the primary T1 line.
DIFF – Dissimilar redundancy mode, in which a different type of
T1 facility exists for both primary and backup lines.
Line Redundancy Switches
LRDN NRVRT, RVRT,
NOBK, OFF
RVRT - Revertive switching. Switches to backup line upon failure
of primary line and then switches back to primary line if primary
line becomes “better” than the backup line or if both the primary
and backup lines are good.
NRVRT - Non-revertive switching. Switches to backup line upon
failure of primary line and then switches back to the primary line
if the primary line becomes “better” than the backup line.
NOBK - No backup line. Notifies controlling CM that no backup line
is available. In this condition, module-only redundancy is
implemented. If primary line fails, the controlling CM does not
switch to the backup line. Also, shelf alerts and alarms are not
generated based on the backup line condition.
OFF - Never switch lines due to line failure.
LSDLY 0S, 0.5S, 1S, 10S Line failure integration time
LRDLY 10S, 1MIN, 5MIN Line redundancy reversion switch delay time
BER OFF, 1E-3, 1E-4,
1E-5, 1E-6
Line failure criteria - Excessive Bit Error Rate. Line failure is
declared if BER exceeds user defined threshold. [Bit Error Rate
(BER) threshold from 1 x 10-3 to 1 x 10-6]
OOF ON, OFF Line failure criteria - Out of frame (OOF) line failure is declared if
receiving OOF.
LOS ON, OFF Line failure criteria - Loss of signal (LOS) line failure is declared if
receiving LOS.
AIS ON, OFF Line failure criteria - Alarm Indication Signal (AIS) line failure is
declared if receiving AIS.
UAS ON, OFF Line failure criteria - Unavailable Signal State (UAS).
Line failure is declared if line is in Unavailable Signal State.
YEL/RA ON, OFF Line failure criteria - Yellow alarm line failure is declared if
receiving Yellow alarm.
Note: Module redundancy ISiCL commands and some line redundancy commands have no
operational effect on the primary CM-5RB module. If the module adapter type is not MA-
235-1 or MA-235-2 (MA type is auto-detected), line redundancy mode is deactivated. In
both instances, from the perspective of the network manager, the ISiCL switch settings for
line redundancy behave normally in that they can be set and read. However, these
commands have no operational effect on the CM-5RB module.
