Reproduced below is an article from the 1 June 1987 Federal Computer Week. Hopefully it is germane to some of the prior net dialog that has been going on. Cermetek Microelectronics Inc. has introduced a second-generation CCITT V32/9600 bit/sec modem, which the company said is the first to feature built-in backward error correcting. The full duplex 9600E supplements the trellis coding and forward error-correcting capability of Cermeteks's 9600 modem, according to the Sunnyvale, Calif., manufacturer. Howard Raphael, Cermetek's chief executive officer, said the forward and backward error correcting "combines to form ultra-reliable data transfer at high speeds over the public switched telephone network, and error prevention is totally transparent to the user." The 9600E model also features synchronous dialing and alternative automatic dial backup via the public network if a leased-line connection fails. Cermetek said the 9600E is the first modem to support the X.25 level LapB, the link layer, error control standard as defined by CCITT, and supports both synchronous and asynchronous transmission, making it compatible with several PC and mainframe commumiction software packages. To ensure international compatiility, Cermetek said the modem conforms to relevant CCITT standards, including V.54 diagnostics, V.25 bis dialing and V.24/28 data terminal interface standard. The 9600E is available with international interfaces and power supplies. Cermetek Microelectronics 1308 Borregas Avenue Sunnyvale, Calif. 94088 Added: Tel No. (408) 734-8150
