- HAYES SUPPORTS V.42bis STANDARD APPROVED BY THE CCITT
-
- ATLANTA, GA., October 2, 1989 - Hayes Microcomputer Products,
- Inc. today announced support of CCITT V.42bis for the company's
- V-series system products. This announcement signifies the company's
- immediate product response to the newest standard for advanced features
- in modems, which was approved by the CCITT Study Group XVII on
- September 29, 1989.
-
- V.42bis specifies the data compression technique used to
- increase throughput of modems incorporating the LAPM error-control
- protocol, bringing an average of three-to-one data compression
- capabilities and as much as four-to-one on some files to the V-series
- system products. The standard is based on the popular Lempel-Ziv
- compression algorithm developed by AT&T Bell Laboratories, and includes
- enhancements proposed by IBM, British Telecom PLC, and Hayes.
-
- In addition, Hayes has signed a letter of intent to enter into
- a patent license agreement with Unisys Corporation. Terms of the
- agreement call for a one-time license fee under Unisys' U.S. Patent
- 4,558,302, which was named for the inventor who first encouraged use of
- Lempel-Ziv technology earlier in the decade. Unisys' timely response
- to licensing requests following the CCITT's approval of V.42bis
- combined with the company's nominal fee made it possible for Hayes to
- utilize this technology.
-
- Beginning December 1, customers who currently have V-series
- system products with V.42 may upgrade to V.42bis through Hayes Customer
- Service. If the product was purchased prior to September 1, there will
- be a $50 charge for the upgrade. Anyone purchasing the product after
- September 1, or anyone who has previously upgraded the V-series system
- product to V.42 will receive the upgrade at no cost.
