A method includes dividing, at a cable modem termination system, a transmit stream into multiple data streams. The multiple data streams include a first data stream and a second data stream. Each of the multiple data streams has a lower bit rate than a bit rate of the transmit stream. The method includes transmitting, via the cable modem termination system, the first data stream over at least a first channel of a group of channels. The method also includes transmitting, via the cable modem termination system, the second data stream over at least a second channel of the group of channels. The group of channels supports traffic to a plurality of destinations. The first channel and the second channel are frequency-division multiplexed channels.

Data service including channel group

A method at a cable modem termination system includes dividing a transmit stream into multiple data streams and transmitting the multiple data streams over multiple radio frequency channels of a group of channels. The group of channels supports traffic to a plurality of destinations. Each channel in the group of channels is a downstream channel.

A method includes receiving, at a transmit site, a first stream of packets addressed to an end user device in a first address space. The first stream of packets is encapsulated to form a second stream of packets addressed in a second address space. A first packet of the second stream of packets is assigned to a first radio frequency channel of a plurality of radio frequency channels. A second packet of the second stream of packets is assigned to a second radio frequency channel of the plurality of radio frequency channels. The first packet is transmitted via the first radio frequency channel and, in parallel, the second packet is transmitted via the second radio frequency channel.

Devices and methods to communicate data streams

A method of sending data from a transmit site to a receive device includes dividing a first transmit data stream having a first bit rate into multiple data streams with each of the multiple data streams having a bit rate that is lower than the first bit rate. Each of the multiple data streams is transmitted over a cable network having multiple radio frequency channels. The multiple data streams are recombined at the receive device to provide a receive data stream having a bit rate equal to the first bit rate. A second transmit data stream is transmitted over one of the radio frequency channels to a legacy user connected to the one radio frequency channel between the transmit site and the receive device.

Method, system, and device for sending data in a cable data service

A method for sending data from a transmit site to a receive site which includes dividing a transmit data stream having a first bit rate into multiple data streams with each of the multiple data streams having a bit rate which is lower than the first bit rate, transmitting each of the multiple data streams over a plurality of RF channels and recombining the multiple data streams at the receive site to provide a receive data stream having a bit rate equal to the first bit rate.

Cable data service method

A transmit and receive system for transmitting data between a transmit site and a receive site. The system includes a tunnel source, router and modulator for dividing a transmit data stream having a first bit rate into multiple data streams with each of the multiple data streams having a bit rate which is lower than the first bit rate, transmitting each of the multiple data streams over a plurality of RF channels. The system further includes a demodulator and destination source for recombining the multiple data streams at the receive site to provide a receive data stream having a bit rate equal to the first bit rate.
