Monday, December 15, 1997 ISSN: 1075-5292 Ascend unveils end-to-end xDSL system Has introduced its DSLTNT central office concentrator Ascend Communications Inc. (Alameda, Calif.) has unveiled a carrier-class concentrator and SDSL-based CPE router which, when combined, provide an end-to-end solution for carriers wishing to provision xDSL services. The DSLTNT central office (CO) concentrator supports a range of xDSL services - including IDSL, SDSL, RADSL-DMT and RADSL-CAP - as well as traditional data services. The concentrator reportedly features the highest port density of any remote access concentrator along with the lower power consumption required by carriers. The DSLPipe-2S is a customer premises router that bonds two SDSL lines together for up to 1.544 Mbps bandwidth (T1). The router also can provide 768 kbps transmission over a single SDSL line. 'It is extremely important to have a flexible platform so that we can adapt our services as market demand evolves,' says Mike Henry, president of MegaINet Inc. (Chicago). The DSLTNT provides 'plug and play' modularity, he says. 'Carriers can only keep up with [xDSL] demand by pulling together their own solutions using multiple products from different vendors,' a method that can be costly and harder to manage, according to Ashok Dhawan, general manager of high-speed access products at Ascend. Carriers and Internet service providers (ISPs) can replace banks of DSL modems, Ethernet switches and routers at the CO with the compact DSLTNT concentrator. The DSLPipe-2S router can support T1-equivalent bandwidth that service providers can, in turn, sell to their corporate customers. The CPE router provides full security, including support for industry-standard PAP and CHAP authorization and authentication protocols, remote provisioning and management, as well as the ability to consolidate IP/IPX and frame relay traffic over the same line, according to Ascend. With one platform, carriers can deliver xDSL services to corporate users, ISPs, and home office workers and telecommuters. A standard 7-ft. rack supports either 1,344 IDSL ports; 1,440 SDSL ports; 540 RADSL-CAP ports; or any mix of services. Plug-in network cards are available for DS3, HSSI, T1, E1, serial WAN, 10BaseT and 100BaseT Ethernet. Moreover, because the system supports a variety of virtual private network (VPN) protocols (including L2TP, PPTP, ATMP, FR Direct and IP Direct), carriers can offer VPN services to corporate customers or segment their own networks so they can resell bandwidth to smaller ISPs. Both systems are part of Ascend's MultiDSL product family. The DSLTNT base chassis with ADSL support lists for $8,900. RADSL-CAP modules were being sold at press time for $4,995 (six-port card). The DSLTNT features softkey upgradability to SDSL and IDSL. The DSLPipe-2S sells for $1,650. ---- INDEX REFERENCES ---- COMPANY (TICKER): Ascend Communications Inc.
