Called party information is provided during survivable processor mode operation of a branch included in a distributed private branch exchange communication system for support of features that require information identifying the called party. More particularly, a coverage path for use during survivable processor operation is enabled that establishes contact with an extension or coverage point over the public switched telephony network such that operation of system appears normal to a caller. Furthermore, for a given coverage point, the same coverage path can be used for a number of extensions, reducing administrative burden.
