Path Protection Over 1+1 Operation
For path protection over 1+1 circuits double fault scenarios are not supported. If both the path protection
and 1+1 are switched, traffic can be lost. To allow path protection functionality the 1+1 must be placed
in “Forced to Working” state. The path protection selector can only be switched manually. To allow 1+1
functionality, the path protection selector must be in “Forced to working” state. In other words, at all
times one of the selectors (path protection or 1+1) must be in the “Forced to Working” state to operate
without traffic loss in this mode.
