A method for detecting translation data error in a central office switch comprises: receiving a call directed to a ported directory number in a switch; retrieving translation data from the switch memory to connect the call to a customer line; and determining that the call cannot be completed to a customer line served by the switch. Upon determining that the call cannot be connected to a customer line served by the switch, a translation data error (TDE) indicator is set in the switch memory so that the instant call, and all subsequent calls directed to the same ported directory number, are connected to an announcement circuit. An translation data error message is also sent to a central switch maintenance and control center by the switch.

[ The invention claimed is:] [1.] In a telecommunications system comprising a plurality of central office switches, wherein a given directory number has been ported from a first of the plurality of switches to a second of the plurality of switches, a method for detecting translation data errors in the second switch comprise the steps of:receiving a call directed to the ported directory number in the second switch;the second switch retrieving translation data to connect the call to a customer line served by the second switch;determining whether the call can be connected to a customer line served by the second switch;storing a translation data error (TDE) indicator associated with the ported directory number in the second switch responsive to the determination that the call cannot be connected to a customer line served by the second switch;extending the call to the first switch; andcompleting any subsequent calls directed to the ported directory number in the second switch in response to the presence of the TDE indicator.
