Twenty-five companies make a major step forward in ISDN interoperability; the California ISDN Users' Group PPP Multilink Protocol Interoperability Workshop proves a success testing ISDN products.SAN FRANCISCO--(BUSINESS WIRE)--March 27, 1995--Twenty-five ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. bridge, router, software, and test equipment companies were able to connect at the California ISDN Users' Group A users' group (also users group or user group) is a type of club focused on the use of a particular technology, usually (but not always) computer-related. PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using Multilink Protocol Interoperability Workshop held on March 20 through 22 at Pacific Bell's San Ramon San Ramon (Spanish for "Saint Raymond") may refer to one of the following places:
These companies tested their implementations of the PPP Multilink Protocol (PPP MP) that provides up to 128 kb/s wire speeds on a single ISDN line by combining two B-channel calls. Pacific Bell provided the facilities, including forty ISDN Basic Rate lines and two ISDN Primary Rate lines to support the workshop. This workshop was organized by Bob Larribeau, a San Francisco based ISDN consultant and a Director of the California ISDN Users' Group (CIUG CIUG Cognos International Users' Group ). Larribeau said, "The ISDN user community definitely wants standards based, interoperable networking products. In particular they want these products to support speeds higher than the 64 kb/s speeds provided by a single ISDN B-channel. Proprietary approaches just don't provide the flexibility and choice that is required to implement large ISDN applications such as work-at-home, telecommuting telecommuting, an arrangement by which people work at home using a computer and telephone, transmitting work material to a business office by means of a modem and telephone lines; it is also known as telework. , and Internet access. The IETF's PPP Multilink Protocol has emerged as the clear choice. The CIUG organized this workshop to get Multilink products to the market as quickly as possible." Having twenty-five companies in the same room, all working together for three days provided a unique opportunity for these companies to verify their PPP MP implementations with a large number of other companies. Ed Klingman, President of ISDN-tek said, "This workshop was a tremendous opportunity to move ISDN forward. It put ISDN-tek a full year ahead of where we would have been without it." PPP MP was developed by the Internet Engineering Task force (c/o Corporation for National Research Initiatives (CNRI), Reston, VA, www.ietf.org) Founded in 1986, the IETF is a non-membership, open, voluntary standards organization dedicated to identifying problems and opportunities in IP data networks and proposing technical solutions to the (IETF See Internet Engineering Task Force. IETF - Internet Engineering Task Force ) as an extension to PPP. PPP (Point-to-Point Protocol) is commonly used for switched and unswitched wide area network connections using TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. and a variety of other network protocols. PPP MP extends PPP so that it can split and recombine re·com·bine v. To undergo or cause genetic recombination; form new combinations. packets over multiple parallel links in order to create a higher aggregate data rate. It can be used to combine the two B-channels in an ISDN Basic Rate line to provide an effective wire speed up to 128 kb/s. PPP MP can also be used to combine B-channels across multiple BRIs or on a Primary Rate line to create even higher effective data rates. Up until now products that combine B-channels to provide wire speeds greater than 64 kb/s on an ISDN Basic Rate line have used proprietary protocols. PPP MP will insure that users will have a wide variety of interoperable equipment available to use ISDN for Internet access or for working at home. The California ISDN Users Group (CIUG) will continue the effort started in this workshop. The CIUG will hold meetings to discuss the progress towards the further implementation of interoperable PPP MP products at its spring conference, "Designing and Implementing ISDN Applications," to be held at the Los Angeles Airport Marriott Hotel on May 31 and June 1, 1995. The CIUG will publish a guide to interoperable PPP MP products at this conference. This guide will also appear on the Internet where it will be maintained as an up-to-date resource guide for implementing ISDN applications with interoperable PPP MP products. The CIUG is in the planning stages for another PPP MP Interoperability Workshop in approximately six months to continue the progress made this week.
