Cable modem termination systems (CMTS) having directional couplers (140) in the primary signal path facilitate redundancy without the need for active components, e.g., primary signal path allows a backup CMTS transceiver (130) to provide redundancy to multiple primary CMTS transceivers (120) through the use of switching outside of the primary signal path.
