Abstract

Apparatus and method for a broadcast communications network for comparing the information received on both a primary and secondary communication link. The absence of a packet of information on the primary link within a predetermined period of time of receipt of a corresponding packet on the secondary link generates an error signal to change the count in a counter in a predetermined direction. When the count reaches a predetermined number the secondary is switched to become the primary link.
