Line Alarm Detection Time

How long it takes for BXM-155(OC3) line to detect alarm such as LOS, Path AIS, and Path Yellow? If BXM line is a trunk, how can I protect connections from rerouting during APS time?

Re: Line Alarm Detection Time

The command:

dsplnalmcnf

Will allow you to see the configuration of alarm times for lines (trunk or not).

cnflnalm

cnftrkalm

will allow you to see (as well as configure) the alarm times.

As I understand it the APS switching time is something like ~60 ms. That will be faster than connections can reroute. On an APS switch to protect you should not see connections reroute off the APS protected trunk.
