A system for providing video-on-demand service, broadband internet access and other broadband services over T-carrier systems including a pull multiplexer cherrypicker at the head end is disclosed. The pull multiplexer receives upstream requests and cull out MPEG or other compressed video packets, IP packets and other data packet types to satisfy the requests or to send pushed programming downstream. The downstream can be DSL or HFC. Each customer has a cable modem, DSL modem or a gateway which interfaces multiple signal sources to a LAN to which settop decoders, digital phones, personal computers, digital FAX machines, video cameras, digital VCRs etc. can be attached. Each gateway can coupled the LAN to a DSL line or HFC through a cable modem or a satellite dish through a satellite transceiver. A PSTN and conventional TV antenna interface is also provided.

The present invention provides the ability to use existing cable TV wires for home networking.

A two way communication system is adapted to reduce latency while the communications system is operating in a low power mode. The two way communication system includes a local host having a first primary communication channel and a secondary out of band transmitter; and customer premise equipment having a primary communication channel for communicating with the first primary communication channel of the local host and a secondary low power out of band receiver that receives out of band control signals from the out of band transmitter during low power operation of the customer premise equipment.

Apparatus for recording and collecting usage and other statistical data from components of a cable data network comprises a network manager for maintaining and collecting the statistics. Internet protocol addresses are associated with components of the network. The component maintains a software agent that manages a statistics database. Responsive to a manager request generated at a service provider defined time interval, the component software agent provides the usage statistics to the network manager in real-time during an Internet session with a host. When the host to Internet or other data connection is torn down due to failure, disconnect or inactivity time-out, remaining usage statistics data is collected and the session duration updated with the time of tear down. Usage statistics collected include the amount of data transferred to / from a host, the amount of data that is discarded due to insufficient resource capacity and amount of data that cannot be corrected despite forward error correction used in a downstream high capacity channel to the host. Data traps may be defined and downloaded to components of the network for implementation. As a result, billing of users of the cable data network can be usage sensitive and determined based on actual data transferred (including credit given for errored data) and / or time sensitive based on session duration.

Systems and methods for providing registration at a remote site that may include, for example, a monitoring module that may communicate with a remote site. A registration protocol may be used by the monitoring module and the remote site in generating the messages communicated during the registration process. The monitoring module may gather and generate various identification information to be included in the registration protocol messages. The registration information provided by the monitoring module may be stored at the remote site in a database server having a database. A confirmation message may be communicated from the remote site to the monitoring module that may either acknowledge successful registration or report that an error occurred during the registration process.

A dynamic channel change technique is disclosed which may be implemented between nodes and a Head End of an access network. Initially a network device may communicate with the Head End via a first downstream channel and a first upstream channel. When the network device receives a dynamic channel change request which includes instructions for the network device to switch to a second downstream channel, the network device may respond by switching from the first downstream channel to the second downstream channel. Thereafter, the network device may communicate with the Head End via the second downstream channel and first upstream channel. Further, according to a specific embodiment, the dynamic channel change request may also include an upstream channel change request for causing the network device to switch from a first upstream channel to a second upstream channel.
