Telmax Communications' ADSL Residential/SOHO Gateway Accelerates Convergence of Voice and Data Services; Supports High-Speed Data and Four Voice Ports Over Single-Pair Copper.Business Editors, High-Tech Writers FREMONT, Calif.--(BUSINESS WIRE)--Jan. 24, 2000 Telmax Communications Corporation, a provider of single-pair Digital Subscriber Line See DSL. (communications, protocol) Digital Subscriber Line - (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and (DSL) access solutions, today introduced the Xiad2000 Asymmetric Digital Subscriber Line (communications, protocol) Asymmetric Digital Subscriber Line - (ADSL, or Asymmetric Digital Subscriber Loop) A form of Digital Subscriber Line in which the bandwidth available for downstream connection is significantly larger then for upstream. (ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line ) remote access unit that enables network service providers to offer telephone, fax or modem service in addition to high speed data over a single copper pair. The Xiad2000 is a next generation spitterless VoDSL residential/SOHO gateway providing &uot;full rate&uot; ADSL high-speed data transport along with four 64kbps &uot;derived&uot; voice channels over a single copper pair linking branch offices, home offices and individual subscribers to their Network Service Providers, including Internet Service Providers. The Xiad2000 design supports CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment interface options such as 4 port integral Ethernet hub, USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. or HPNA. According to Telmax Communications' Vice President of Marketing Franchesca Walker, &uot;The Xiad2000 residential/SOHO gateway finally provides customers and service providers voice, with full CLASS services, along with high-speed data service at a lower cost.&uot; Using industry standard Discreet Multi-Tone (DMT See DSL. ) technology, the Xiad2000 supports the ANSI (American National Standards Institute, New York, www.ansi.org) A membership organization founded in 1918 that coordinates the development of U.S. voluntary national standards in both the private and public sectors. It is the U.S. member body to ISO and IEC. T1.413 issue 2 standard, TR 57 and TR909. The initial release of the product will interoperate with Jetstream's voice gateway and followed quickly by releases supporting other vendors' voice gateways. The Xiad2000 interfaces to central office DSL Access Multiplexers (DSLAMs) at speeds from 32 kbps to 8 Mbps downstream and from 32 kbps to 1 Mbps upstream, selectable in increments of 32 kbps. The Central Office equipment provides Asynchronous Transfer Mode See ATM. (communications) Asynchronous Transfer Mode - (ATM, or "fast packet") A method for the dynamic allocation of bandwidth using a fixed-size packet (called a cell). See also ATM Forum, Wideband ATM. ATM acronyms. Indiana acronyms. (ATM) aggregation over ADSL to each copper loop, resulting in a robust quality of service. The Xiad2000 requires no line conditioning on the pairs, providing binder group integrity along with pairs carrying traditional POTS service. The Xiad2000 is designed for use worldwide, providing selectable A-law and Mu-law PCM analog conversion. The four 64kbps clear channel lines provide all telco CLASS service (caller ID, call waiting, selective ringing, etc.) plus fax and modem capability without compression, bit robbing or statistical multiplexing and echo cancellation. The upstream and downstream data rates are dynamically allocated across the DMT spectrum to minimize noise and maximize service reliability. Each session automatically re-configures the rate to attain optimal communication. Using industry standard interface options such as Internet Protocol (IP) over Ethernet and IP over ATM, the Xiad2000 immediately connects customers to synchronous and asynchronous Refers to events that are not synchronized, or coordinated, in time. The following are considered asynchronous operations. The interval between transmitting A and B is not the same as between B and C. The ability to initiate a transmission at either end. networks. The Xiad2000 is easily installed over an existing analog telephone service, supporting analog voice along with state-of-the-art digital services. Available early in the second quarter of 2000, the Xiad2000 lists for $695.
