A method for performing ONU Management and Control Interface (OMCI) synchronization includes receiving an OMCI message containing a OLT-G entity identifying OLT's vendor identification (ID) and version. The method also includes determining if an OLT vendor identification (ID) matches with a current vendor ID and if an Optical Line Terminal (OLT) version is compatible with current OMCI handlers. When the OLT vendor ID fails to match with the current vendor ID, automatically performing a OMCI handler switching process. The OMCI handler switching process includes setting a current OLT vendor as a new OLT vendor ID, deleting a OMCI configuration previously stored in the flash memory after setting the new OLT vendor ID, and rebooting the ONT to allow the ONT to initialize a OMCI configuration using a new OMCI profile.

Configuring an optical network termination

A process for configuring an optical network termination (ONT) includes receiving an upstream overhead physical layer operation administration and maintenance (PLOAM) message from an optical line terminal (OLT). The process also includes extracting byte 10 data from the upstream overhead PLOAM message to identify a transceiver type of the OLT, and matching the transceiver type of the OLT with one of a plurality of sets of optical parameters. The process further includes storing the matched transceiver type of the OLT in a double date rate (DDR) memory prior to completing a ranging process with the OLT.
