An access network comprises a first network interface device coupled to a customer network and configured to provide an interface between the access network and the customer network. The access network also comprises a second network interface device coupled to a core network and configured to provide an interface between the access network and the core network. The first network device is configured to insert a Status Type Length Value (TLV) element into a Continuity Check Message (CCM) to form a modified CCM and to transmit the modified CCM to the second network interface device. The Status TLV element includes fields for at least one of a dying gasp indication from a customer premise equipment or performance monitoring data. The second network interface device is configured to store data from the Status TLV in a database entry associated with an identification number of the first network interface device.
