ABSTRACT:
A proxy in a cable modem termination system receives IP packets having an address associated with set top box out of band messages. The proxy encapsulates the packets in an Ethernet frame containing an Ethernet address. A cable modem associated with the set top box is preconfigured to detect the Ethernet encapsulated packets and pass the out of band messages in the packets to the set top box.
