Gateway P-173 Agere Modem Driver
In part, DOCSIS sets forth requirements and objectives for various aspects of cable modem systems including operations support Gateway P-173 Agere Modem, management, data interfaces, as well as network layer, data link layer, and physical layer transport for cable modem systems. In accordance with the DOCSIS specification, a media access control frame MAC is applied to each data packet transmitted and is used to convey information about the data packet as it is passed through the system from one component to the next.
As shown in FIG. The Data Gateway P-173 Agere Modem portion contains the payload data such as voice or text data for example.
Heretofore, cable modems and cable modem termination systems have relied upon the host Gateway P-173 Agere Modem system and software to generate the DOCSIS header. Reliance upon software, however, results in significant processing overhead. Thus, what is needed is an apparatus and method for creating DOCSIS headers in hardware such that the performance of the overall system is improved.
If it is determined that the data packet needs to be encrypted, then the DOCSIS header creator circuit is further able to generate an encryption flag. The cable modem system enables voice communications, video and data services based on a bi-directional transfer of packet-based traffic, such as Internet Gateway P-173 Agere Modem IP traffic, between a cable system headend and a plurality of cable modems over a hybrid fiber-coaxial HFC cable network In the example cable modem systemonly two cable modems and are shown for clarity.
In general, any number of cable modems may be included in the cable modem system of the Gateway P-173 Agere Modem invention. The cable headend is comprised of at least one cable modem termination system CMTS The CMTS is the portion of the cable headend that manages the upstream and downstream transfer of data between the cable Gateway P-173 Agere Modem and the cable modems andwhich are located at the customer premises.
The CMTS broadcasts information downstream to the cable modems Gateway P-173 Agere Modem as a continuous transmitted signal in accordance with a time division multiplexing TDM technique. Additionally, the CMTS controls the upstream transmission of data from the cable modems and to itself by assigning to each cable modem and short grants of time within which to transfer data.
In accordance with this time domain multiple access TDMA technique, each cable modem and may only send information upstream as short burst signals during a transmission opportunity allocated to it by the CMTS In embodiments, the Gateway P-173 Agere Modem network comprises the Internet. In addition to the CMTSthe cable headend may also include one or more Internet routers to facilitate the connection between the CMTS and the packet-switched networkas well as one or more servers for performing necessary network management tasks.
The HFC network provides a point-to-multipoint topology for the high-speed, reliable, and secure transport of data between the cable headend and the cable modems and at the customer premises. As will be appreciated by persons skilled in the relevant art sthe HFC network may comprise coaxial cable, fiberoptic cable, or a combination of coaxial cable and fiberoptic cable linked via one or more fiber nodes. Each of the cable modems and operates as an interface between the HFC network and at least one attached user device.
In particular, the cable modems and perform the functions necessary to convert downstream signals received over the HFC network into IP data packets for receipt by an attached Gateway P-173 Agere Modem device. Additionally, the cable modems and perform the functions necessary to convert IP data packets received from the attached user device into upstream Gateway P-173 Agere Modem signals suitable for transfer over the HFC network In the example cable modem systemeach cable modem and is shown supporting only a single user device for clarity.
In general, each cable Gateway P-173 Agere Modem and is capable of supporting a plurality of user devices for communication over the cable Gateway P-173 Agere Modem system User devices may include personal computers, data terminal equipment, telephony devices, broadband media players, network-controlled appliances, or any other device capable of transmitting or receiving data over a packet-switched network.

Furthermore, in the example cable modem systemthe CMTS operates to receive and process data packets transmitted to it in accordance with the protocols set forth in the DOCSIS specification. Accordingly, the CMTS will be described in terms of a receiver portion Gateway P-173 Agere Modem a transmitter portion. The receiver portion includes an optical-to-coax stagean RF inputa splitterand a plurality of burst receivers Reception begins with the receipt of upstream burst signals originating from one or more cable modems by the optical-to-coax stage via the optical fiber The optical-to-coax stage routes the received burst signals to the radio frequency RF input via coaxial cable In embodiments, these upstream burst signals having spectral characteristics within the frequency range of roughly MHz.
Gateway P-173 Agere Modem of the N separate channels is then provided to a separate burst receiver which operates to demodulate the received signals on each channel in accordance with either a Quadrature Phase Shift Key QPSK Gateway P-173 Agere Modem 16 Quadrature Amplitude Modulation QAM technique to recover the underlying information signals. Ascendtech will cover return shipping on replacement item sent back to customer.
