following options:
Option
453
Description
Monitor Mode is currently not supported.
This is used as an attempt to recover the signal in the event
the SDH's client processor signal (Packet tab, etc) is in an
alarm state such as Loss of Frame or Loss of Link.
•
By setting this to Default, the SDH processor will
refresh every 30 seconds or so, which gives the client
processor an opportunity to re-acquire a good framing
or link.
•
By setting this to Alternate, then the SDH processor
will not try to auto-recover (refresh) when the client
processor framing or link state is bad. You may need
to force an LOS event (and then clear the LOS event)
after the signal failure has been resolved, for the client
to re-acquire client framing or link state.
Signal Auto-Recovery Method is only supported on the
MPM-10G card.
