WTR: Wait To Restore.
-
It’s a timer used to improve the network stability.
-
It’s used only with revertive switching mode.
-
It’s the Time from switching the traffic path from main to standby (if failure occurred with main) to the switch back to main when main become available.
-
WTR can be controlled by NMS.
-
It’s by default 10 minutes (600 sec).
-
Can be set from 5 to 12 minutes.
-
In non revertive mode we are not able to set WTR because the link will not forced to switch to main.
-
In non revertive mode the traffic will stay flowing through the avilable path regardless it’s the main or standby.
-
Switching types can be single ended or dual ended.
-
Switching time should not be greater than 50 m seconds.
