Parameters for viewing MSP protection
...................................................................................................................................................................................................................................
Working section
Displays the working sections of the selected MSP group.
Protection section
Displays the protection of the selected MSP group.
Active section
Displays which section is carrying traffic.
Switch state
Displays the current switch state of the protection pair.
Selected pair
Displays the selected sections and indicates the alarm status at the working/protection
port. This can be Error Free, Failed, or Degraded.
Communication mode
Displays whether the protection is unidirectional or bidirectional. In the case of failure
with unidirectional mode the receive side switches. In the bidirectional mode both sides
are switched. When the unidirectional mode is displayed the Far End selection is
greyed out.
WTR (wait to restore/wait to rename)
If MSP mode is ETSI, WTR is the wait to restore time after the failure on the
protected unit has cleared. If msp mode is 1+1 optimized, then WTR is the Wait to
rename: after the failure on the protected unit has cleared, the traffic remains on the
protection, but the current primary becomes secondary and the other way around.
Near end
Displays the service reference at the Near/Far end. This can be Working, Protection, or
None. Also the APS transmitted code is displayed.
