Microcom Inc, specialising in communications software for workstations and based in Norwood, Massachusetts, has won a contract to supply modems to Telenet Communications Corp for the X25 US and international Telenet Public Data Network. Telenet wants the Microcom Networking Protocol class 6 modems to provide higher dial speeds, faster file transfers, and shorter interactive response times in 24 US cities, beginning this week. Running at up to 19.2Kbps over dial-up lines, the AX/9624c modem features the statistical duplexing and universal link negotiation features provided by the Microcom protocol. This enables the modem to compare data transmission speeds available on each modem at the other end of the line, selecting the highest possible speed common to both modems. The protocol is also conceived to enable high performance in bulk file transfer applications. The AX/9624c also includes Microcom’s class 5 protocol which is claimed to increase performance by 200%. Telenet with over 100 private data networks and more than 20 electronic messaging systems worldwide was the first to endorse the Microcom protocol as an emerging standard, back in 1983.
