摘要： A system and method for autonomous data path verification in a multi-module shelf configuration, such as in a digital cross-connect system, are disclosed. The system generally includes a source port module, a destination module, and optional n-stage network of mapping interface modules. The source port module is configured to reuse transport overhead bytes of received SONET or SDH signals by inserting data path verification data therefor. The destination module is configured to perform autonomous data path verification between the source port module and the destination module by examining the reused transport overhead bytes of the signals received from the source port module. The method generally includes reusing transport overhead bytes by inserting data path verification data into the overhead bytes of signals received by a first module, e.g., a source port module, and transmitting the signals with the data path verification data toward a second module, e.g., a destination port module. The second module emits a confirmed or unconfirmed pattern upon detecting presence or absence of an expected pattern in the reused transport overhead bytes, respectively, and reports changes in the received pattern to facilitate autonomous data path verification.
