Abstract
A first device receives, over a first communications link, a container frame having a payload of a first length. The payload of the container frame includes multiple optical transport unit (OTU) frames of a second length. The first length is not a multiple of the second length. Each of the OTU frames includes an optical data unit (ODU) frame, a sequence of forward error correction (FEC) bits for the ODU frame, and a sequence of error-identifying bits for the ODU frame. The first device determines, based on the sequences of error-identifying bits, a performance of the first communications link.
