ABSTRACT:
An integrated multiple cross-connect system (10) having remotely located components interconnected by integrated office links is provided. The system (10) includes a broadband matrix (20), at least one remotely located high speed line terminating equipment (30, 32) coupled to a telecommunications network, and an integrated office link (34, 36) interconnecting the broadband matrix (10) and high speed line terminating equipment (30, 32), the integrated office link (34, 36) carrying duplex transmission of an IOL-N signal of N multiplexed STS-1P optical signals at an OC-N rate, the STS-1P signal including data payload and overhead fields. Further included is a remotely located wideband matrix (22), a second integrated office link (40) interconnecting the broadband matrix (20) and the remotely located wideband matrix (22), and at least one remotely located low speed line terminating equipment (54) coupled to a telecommunications network, where the wideband matrix (22) and low speed line terminating equipment (54) are interconnected by a third integrated office link (59). Fault coverage information including a cross-connect channel identification code and a parity value are among the IOL overhead fields. The fault coverage information in the IOL overhead fields are monitored at selected points along a transmission path.
