Patent ID: 8259944

Claim:
A system for protection against pathological patterns in a Frame Synchronous Scrambled network communication, the system comprising: at least one transmitter comprising: at least one pathological pattern detector that detects one or more undesirable bit patterns in an incoming traffic stream; and at least one bit pattern modification module that modifies the one or more undesirable bit patterns to produce a modified traffic stream; wherein the at least one transmitter transmits the modified traffic stream; wherein the at least one bit pattern modification module comprises: a replacement pattern generator that generates at least one replacement bit pattern; at least one multiplexer that replaces at least a portion of the one or more undesirable bit patterns with the at least one replacement bit pattern; an insertion pattern generator that generates at least one insertion pattern; and at least one multiplexer that inserts the at least one insertion bit pattern into the one or more undesirable bit patterns of the incoming traffic stream.
