Intel licenses Always On/Dynamic ISDN software

Intel is to license a key piece of networking technology that gives PCs access to Always On/Dynamic ISDN (AO/DI), a communications standard that helps reduce congestion on networks operated by ISPs and local telephone companies. AO/DI uses ISDN's D Channel to establish a constant low-bandwidth connection between users and their ISP, corporate network, or the other end of a video conference call. When the user needs more bandwidth to complete a specific task, the connection switches to the higher-speed B Channel.

Intel is to license a key piece of networking technology that gives PCs access to Always On/Dynamic ISDN (AO/DI), a communications standard that helps reduce congestion on networks operated by ISPs and local telephone companies.

The networking technology was designed by software developer NetManage to operate over ITK Telecommunications ISDN hardware and software, which are included in the Intel's Business Video Conferencing with ProShare Technology product. The AO/DI standard was advanced by The Vendor's ISDN Association.

AO/DI uses ISDN's D Channel to establish a constant low-bandwidth connection between users and their ISP, corporate network, or the other end of a video conference call. When the user needs more bandwidth to complete a specific task -- such as sending an e-mail message or downloading information from the Internet -- the connection switches to the higher-speed B Channel. When the task is completed, the connection moves back to the lower-speed D Channel.

Intel plans to license the technology for use in current and future products developed for transmission via the dial-up H.323, or LAN, (LAN) communication standard. AO/DI is a bridge between the H.320, or ISDN, videoconferencing standard widely used by most businesses today and the rapidly emerging LAN videoconferencing standard.

AO/DI gives businesses the advantage of ISDN dial-up network access and H.323 performance without losing the ability to contact H.320 videoconferencing systems, said Scott Darling, general manager of the Intel Business Communication Products Operation.

"Even when connected to an H.320 video conference call, a user still has access to a corporate network through an ISDN line's D channel," Darling said.

Intel's announcement follows a technical trial completed in October by BellSouth at its Solutions Validation Test Lab in Birmingham, Alabama. BellSouth tested AO/DI capabilities with NetManage software and ITK Telecommunications ISDN hardware and software. BellSouth has endorsed AO/DI as a more effective means for business customers to connect to the Internet and intranet from home or remote locations.
