Abstract:
1. A method for optimizing a communication system comprising: remote control of slicing level of a receiver in a first transceiver in the communication system, said communication system further comprising an operating system with Operation, Administration, and Maintenance (OAM) and Protocol functions, an OAM, Protocol & Payload Processor, a second transceiver, Bit Error Rate Test (BERT) equipment, and an optical link, wherein remote control of slicing level of the receiver in the first transceiver comprises: a first operation comprising configuring the first transceiver to be in a loopback mode; a second operation comprising enabling the BERT equipment to transmit a pseudo-random (PRN) bit stream to the first transceiver, the first transceiver transmitting the PRN back to the BERT for bit error rate (BER) measurement, and recording of the measured BER; a third operation comprising the second transceiver transmitting a slicing level adjustment Protocol message to the first transceiver, and the first transceiver adjusting its slicing level according to the slicing level adjustment Protocol message; a fourth operation comprising enabling the BERT equipment to transmit a pseudo-random (PRN) bit stream to the first transceiver, the first transceiver transmitting the PRN back to the BERT for measuring the BER; a fifth operation comprising repeating the third and fourth operations until an optimum slicing level based on the measured BER recordings is found; and a sixth operation comprising transmitting a slicing level adjustment Protocol messaging containing the optimum slicing level to the first transceiver, and the first transceiver adjusting its slicing level based on the optimum slicing level.
