CableLabs Issues RFI for an Integrated DOCSIS Access Device for Commercial Applications.LOUISVILLE, Colo. -- CableLabs(R) has issued a request for information (RFI (Radio Frequency Interference) High-frequency electromagnetic waves that emanate from electronic devices such as chips. RFI - Radio Frequency Interference ) for Integrated DOCSIS (Data Over Cable Service Interface Specification) A cable modem standard from the CableLabs research consortium (www.cablelabs.com), which provides equipment certification for interoperability. (R) Access Device (IDAD IDAD Internal Defense And Development IDAD Institute of Destination Architects and Designers (Cincinnati, OH, USA) IDAD Initiative for Domestic Animal Diversity IDAD Ich Denk An Dich (Germany) ) equipment. The IDAD will enable cable operators to offer voice and data services for small business and commercial customers. RFI responses are due January 14, 2005. For several years, cable television operators have been transitioning from a traditional core business of entertainment programming to a position as full-service triple-play providers of video, voice, and data telecommunications services. DOCSIS cable modems and headend devices are among the fundamental elements making this transition possible. To date, the most successful and cost-effective method for providing high-speed data services is via equipment based on DOCSIS specifications. DOCSIS equipment also serves as the basis for PacketCable(TM) and Voice over Internet Protocol See Internet and TCP/IP. (networking) Internet Protocol - (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. (VoIP) services. Some cable television operators are expanding telecommunications service offerings to include T1 and related services using DOCSIS-based network equipment. By providing a common set of requirements for IDADs, CableLabs anticipates that enough scale could be provided to enable one or more vendors to offer products economically and in a timely manner. An IDAD is envisioned to be a multifunctional device, providing client interfaces ranging from traditional DS0 level FXS (Foreign eXchange Station) The interface provided by the telephone company to its customers, which includes dial tone, power and ring voltage. The telephone jack on the wall is an FXS interface. services to fully functional DS1 interfaces to 100 Base T. The network interface at the customer premises is a standard RF coaxial cable that has a frequency range up to 860 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. downstream and a return path operating in the range of 5 MHz to 42 MHz. The IDAD is similar to a Multi-Line Multimedia Terminal Adapter See ISDN terminal adapter. terminal adapter - Terminal Adaptor (ML-MTA) in that it will be PacketCable-based for voice services. It goes beyond that specification, however, to include DS1 circuit-emulation - via IP - over DOCSIS. Founded in 1988 by members of the cable television industry, Cable Television Laboratories is a non-profit research and development consortium that is dedicated to pursuing new cable telecommunications technologies and to helping its cable operator members integrate those advancements into their business objectives.
