ABSTRACT:
The need for manual verification of service on a desired cross-connect in a cross-connect system prior to provisioning may be eliminated by modifying the logic of the cross-connect system to take account of an internal indication characteristic of whether service is present on the cross-connect. Upon receipt of a NORMAL command, the cross-connect system only executes the command to disconnect the cross-connect when no service is present. However, upon receipt of a FORCED command, the cross-connect system executes the command to disconnect the cross-connect irrespective of the existence of any service thereon. Moreover, in response to an indication of service and denial of the NORMAL command, a FORCE command may be issued instead to effect disconnection of the cross-connection with such disconnection is desired irrespective of the existence of service thereon.
