Abstract

A method of rerouting a digital infra-office signal through a telephone central office comprises the steps of retrieving identification data for ports of first and second digital access and cross-connect systems, the ports being connected by an infra-office digital trunk, retrieving identification data for an alternative path from the first cross-connect system to the second cross-connect system, correlating identification data for the alternative path to the identification data for the infra-office digital trunk, determining availability of and displaying alternative path data responsive to entry of identification data for the infra-office digital trunk, and rerouting the infra-office digital signal via the alternative path.
The rerouting of digital infra-office signals through a telephone central office may be necessitated by preventative maintenance, repair and replacement of connectors and the like, to install new bays or frames of equipment and to restore service in the event of a service outage or imminent failure.
