Methods and apparatuses for automatic configuration of ports in an optical network

A first transport equipment for an optical network, wherein the first transport equipment is configured to communicating with a second transport equipment in an optical network to transmit traffic between a local terminal device and a remote terminal device, the first transport equipment comprising processing circuitry configured to:

• receive traffic from a local terminal device intended for a remote terminal device;
• attempt to decode the traffic according to a first coding type to generate decoded traffic;
• determine an alignment status of the decoded traffic;
• and
• responsive to an alignment status of the decoded traffic indicating a loss of frame, attempt to decode the traffic according to a second coding type;
• wherein the processing circuitry is further configured to receive from the second transport equipment, on line overhead, an indication of a remote alignment status indicating whether the second transport equipment has decoded traffic from the remote terminal device with a loss of frame, and a current remote coding type.
