GREENSBORO, N.C. -- April 1, 1999 - The response to our introduction of Tachyon Transmission Mode (TTM) in our February 1, 1999 newsletter has been overwhelming.

TTM is a proposed standard, based on patent-pending technology invented by Distributed Networking Associates, for a reverse-time mechanism that will enable the development of the Information Airline (a successor to the Information Superhighway).

In case you missed the earlier newsletter, we discussed the problem of "clipping" when Voice Activity Detection (VAD) is used with traditional circuit switching. Clipping refers to the initial sounds of a voice transmission being cut off due to the time lag between detecting the sound and turning on the transmitter. One solution in the circuit-switched world is to use sophisticated (and expensive) circuitry to introduce delay. The other is to use TTM to detect the presence of traffic, then turn on the transmitter circuits several milliseconds prior to the detection.

In the packet world, TTM also solves the thorny problem of windowing out due to inherent delays caused by the speed of light. Whether the technology used is ATM, frame relay, or IP, this windowing problem severely limits the throughput for any data in which assured transmission is required. (Note that one of the little-known down sides to fiber-optic transmission is that the speed of light is almost 50% slower using this medium compared with the speed of light in a vacuum.)

TTM, with its Bilateral Ultra Low Luminescence Coupled Resonance Attenuated Phase technology eliminates this problem by using tachyons for warp-speed transmissions.

The space limitations of this newsletter limit the amount of detail that can be divulged about TTM. However, a full explanation is available in the Public Forum at Webtorials.Com. In addition to the technical nitty gritty, you'll find expert commentary on the future of TTM from: Network World Editor-in-Chief John Gallant; noted industry analysts Robbie Forkish (Forkish Consulting); William Flanagan (NetReference); Kathryn Korostoff (Sage Research); Fred McClimans (Current Analysis); Thomas H. Jones (WNP Communications); Jim Cavanagh (Consultant); Rick Malone (Vertical Systems Group); and representatives of AT&T, Inverse Network Technology and Hitachi Telecom.

Send us e-mail at to let us know your thoughts. We will summarize the responses and let you know what your cohorts are thinking.

Steven Taylor, consultant and broadband packet evangelist, and Joanie Wexler, an independent networking technology editor and writer, team up to bring you this analysis and commentary. Taylor specializes in education and market analysis, and Wexler adds incisive reporting and research. For more detailed information on most of the topics discussed in this newsletter, connect to, the first Web site dedicated exclusively to market studies and technology tutorials in the Broadband Packet areas of Frame Relay, ATM, and IP.
