Abstract
In a frame synchronous scrambled communications network, communications are protected from pathological bit patterns that may lead to loss of receiver lock by detecting a pathological bit pattern in an incoming traffic stream using a pathological pattern detector. When a pathological bit pattern, such as a transition-less bit pattern, is detected, a corrective bit pattern is generated and inserted or substituted into the incoming traffic stream before transmission to the receiver. The receiver can be configured to revert the modified traffic stream back to the original traffic stream.
