ABSTRACT:
A multiplex transmission system is disclosed in which, in the event of a problem between a converter and a client device on the transmitting side, the occurrence of this problem is reported to a converter on the receiving side without using specially dedicated frames. When a problem occurs between the converter on the transmitting side and an FC device on the transmitting side and the loss of optical input (LOS) or the loss of character synchronization (LCS) is detected, the converter on the transmitting side uses values that are not being used of the control character indicators of compression control codes in 64B/65B codes following 64B/65B conversion to transmit to the converter on the receiving side the alert information LOS or LCS. The converter on the receiving side, upon detecting this alert information, transmits a 10B-ERR signal or halts optical output to the FC device on the receiving side.
