US West, Ameritech Ready 'Always-On ISDN' Services November 18, 1998 PC Week: Several telecommunications companies are readying an enhancement to their ISDN services that could give corporations a low-cost method of remote access. US West Communications and Ameritech Corp. plan to roll out next year " always- on ISDN" services, joining Regional Bell Operating Companies SBC Communications Inc. and BellSouth Corp., which already offer the service in their respective territories. Bell Atlantic Corp. and GTE Corp. are both evaluating the service. The service lets users maintain constant 9.6K-bps connections to a corporate LAN or the Internet over an ISDN circuit's D channel, instead of racking up usage charges by connecting both of an ISDN circuit's B channels. The connected D channel has sufficient bandwidth for receiving small data streams, such as e- mail headers or news updates. When a user requires more bandwidth than the D channel can provide, the service automatically activates one or both of the B channels, which shut down automatically when they're no longer needed. In most instances, the D channel capability is offered for a small, additional monthly fee. In SBC's territory, for example, the feature costs $5 a month, except in Texas, where it's $2 a month. The always-on ISDN feature "certainly makes sense in some environments, " said Jeffrey Fritz, principal network engineer at West Virginia University, in Morgantown. "It handles maintenance traffic and e-mail pretty well." US West, of Denver, will introduce its service in the first quarter of next year. Chicago-based Ameritech will debut its service by midyear. In Atlanta-based BellSouth's region, business customers can assemble the service by buying components from BellSouth's ISDN tariffs for $15 a month. In SBC's territory, the service, which has been available since late 1997, " provides a real nice economic service model" for many remote business customers, said Don Norman, SBC product director in San Antonio. <<PC Week -- 11-16-98>> [Copyright 1998, Ziff Wire]
