EFFICIENT NETWORKS AND CONEXANT TO REDUCE SDSL CONNECT TIMES AND PROVIDE EXPANDED INTEROPERABILITY.Efficient Networks (Nasdaq:EFNT) has announced that the next release of its SpeedStream(R) 5851 symmetric digital subscriber line Symmetric Digital Subscriber Line (SDSL) is a Digital Subscriber Line (DSL) variant with E1-like data rates (72 to 2320 kbit/s). It runs over one pair of copper wires, with a maximum range of about 3 kilometers. (SDSL See DSL.
SDSL - Single-line Digital Subscriber Line ) router and SpeedStream 7451 integrated access device An IAD is a customer premises device that provides access to wide area networks and the Internet. Specifically, it aggregates multiple channels of information including voice and data across a single shared access link to a carrier or service provider PoP (Point of Presence). (IAD (Integrated Access Device) A device that multiplexes a variety of communications technologies in the customer's premises onto a single telephone line for transmission to the carrier. It also demultiplexes the incoming streams into their respective channels. ) will support AutoBaud operation, a technology developed by Conexant Systems Inc. (Nasdaq:CNXT) to speed SDSL service deployments and interoperability.
By incorporating Conexant's ZipWire SDSL solution, Efficient Networks offers customers faster connect times, quicker recovery from circuit changes, freedom from time-consuming pre-provisioning and greatly expanded interoperability with a wide range of central-office systems.
The SpeedStream 7451 next-generation IAD is designed for small businesses, remote and branch offices, home offices and telecommuters requiring telephone and fax features, as well as high-speed Internet See broadband. and corporate access. It is optimized for high-bandwidth business applications such as Web-based research or transport of large e-mail attachments A file that rides along with an e-mail message. The attached file can be of any type. E-mail programs make it easy to attach a file. For example, in Eudora, all you do is select Attach from the Message menu, browse through the folder hierarchy to find the file you want and then double .
Conexant's AutoBaud technology is designed to enhance the connection set-up process between SDSL equipment operating at any one of the line rates that SDSL technology supports, and to reduce time-consuming, manual-line qualification. AutoBaud allows carriers to automatically qualify and determine the maximum data rate supported by the line, alleviating the need for sending a service technician.
In addition, AutoBaud enhances interoperability by allowing the premises device to sense central office equipment in use, thus enabling it to load the appropriate Layer 2 protocols prior to the connection being established.?
