DOCSIS employs a mixture of deterministic access methods for upstream transmissions, specifically time-division multiple access (TDMA) for DOCSIS 1.0/1.1 and both TDMA and S-CDMA for DOCSIS 2.0 and 3.0, with a limited use of contention for bandwidth reservation requests. In TDMA, a cable modem requests a time to transmit and the CMTS grants it ...
The Multimedia over Coax Alliance (MoCA) is an international standards consortium that publishes specifications for networking over coaxial cable.The technology was originally developed to distribute IP television in homes using existing cabling, but is now used as a general-purpose Ethernet link where it is inconvenient or undesirable to replace existing coaxial cable with optical fiber or ...
For instance, SATA revision 3.0 (6 Gbit/s) controllers on one PCI Express 2.0 (5 Gbit/s) channel will be limited to the 5 Gbit/s rate and have to employ more channels to get around this problem. Early implementations of new protocols very often have this kind of problem.
If the HFC network is large, the cable modem termination system can be grouped into hubs for efficient management. Several standards have been used for cable internet, but the most common is DOCSIS. [1] A cable modem at the customer is connected via coaxial cable to an optical node, and thus into an HFC network.

DVB-C2, an enhanced version of the DVB-C digital cable TV standard; Power line communication (PLC) ITU-T G.hn, a standard which provides high-speed local area networking of existing home wiring (power lines, phone lines and coaxial cables) [13] TrailBlazer telephone line modems; Multimedia over Coax Alliance (MoCA) home networking; DOCSIS 3.1 ...
To cope with needs for increased digital bandwidth such as for DOCSIS internet, cable operators have implemented expansions in the RF spectrum in HFC networks beyond 1 GHz to 1.2 GHz, [71] [72] have transitioned to only handling IP traffic in the network thus eliminating dedicated video RF channels, used digital transport adapters (DTAs) for ...
Additionally, V.34 modems employ shell mapping as shaping code to reduce the transmit power. [5] V.34 (10/96) is an updated ITU-T recommendation for a modem, building on the V.34 standard but allowing up to 33.6 kbit/s bidirectional data transfer. Other additional defined data transfer rates are 31.2 kbit/s, as well as all the permitted V.34 rates.
