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 ...
DOCSIS RFI 1.1 [16] later added more robust and standardized QoS mechanisms to DOCSIS. DOCSIS 2.0 added support for S-CDMA PHY, while DOCSIS 3.0 added IPv6 support and channel bonding to allow a single cable modem to use concurrently more than one upstream channel and more than one downstream channel in parallel.
Video can be encoded according to standards such as NTSC, MPEG-2, DVB-C or the QAM standard and data according to DOCSIS, analog video can be scrambled, [12] signals can be modulated by analog or digital video modulators including QAM modulators [13] or edge QAMs for video and/or data depending on whether a modular CMTS is used, at the CMTS for ...
Cable modem termination system. A cable modem termination system (CMTS, also called a CMTS Edge Router) [1] is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers.
The BT Home Hub 2.0 was a combined wireless router and phone. It supports the 802.11b/g/n wireless networking standards, and the WEP and WPA security protocols. [9] It supports many of BT's services such as BT Fusion, BT Vision and BT Broadband Anywhere. It can also be used as a VOIP phone through BT Broadband Talk.
The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is a standardised architectural framework for delivering IP multimedia services. Historically, mobile phones have provided voice call services over a circuit-switched-style network, rather than strictly over an IP packet-switched network.
This version enables IP telephony by providing simple and generic methods for making connections between two (using H.323) or more (using IP multicast) computers and now also offers the ability to access any media stream (MSP driver) involved in the connection. Windows XP included both TAPI 3.1 and TAPI 2.2.
