Abstract
A system and method for providing redundancy in an integrated circuit (IC) relay device has been disclosed. The relay device accepts communications on a first and second receive path. The relay device monitors communications on both the receive paths, and selects a path having a high degree of integrity. Likewise, the relay selectively supplies communications on a first and second transmit path. The relay device selects the transmit path having the proper measure of communication integrity. Communications integrity can be based upon internally monitored criteria such as bit error rate, synchronization, clock signals, and forward error correction. Alternately, the integrity is determined external to the relay, and the relay responds to external switch commands.
