Abstract
In one aspect of the present invention, a network gateway is configured to facilitate on line and off line bi-directional communication between a number of near end data and telephony devices with far end data termination devices via a hybrid fiber coaxial network and a cable modem termination system. The described network gateway combines a QAM receiver, a transmitter, a DOCSIS MAC, a CPU, a voice and audio processor, an Ethernet MAC, and a USB controller to provide high performance and robust operation.
Claims24
A cable modem comprising:
- a network port to interface with a cable head end;
- a telephony port to interface with a telephony device;
- a data port to interface with a data terminal;
- a processor coupled to the telephony port and the data port;
- and
- a transceiver coupled between the processor and the network port including a media access controller (MAC) coupled to the processor, a modulator and a demodulator disposed between the MAC and the network port.
