[ HAYES 9600 Modem Features ] This file was put together in an effort to disspell some of the rumors and inaccuracies about the recently-announced HAYES 9600 baud modems. Well, HAYES finally announced their new line of 9600 baud modems, known as the V-Series. Of course, these modems are not compatible with any of the 9600 baud modems currently on the market (as of 6-18-87). There are, however, quite a few similarities between the HAYES V-Series, and the U.S. Robotics Courier HST 9600 modem, which the HAYES seems to be patterned after, but not identical to. Three versions were announced at the big COMDEX show in Atlanta last week. First, there is the external, known as the V-series Smartmodem 9600(TM). The modem is physically similar in both appearance and size to the HAYES Smart- modem 2400(TM). It is, of course, fully compatible with its lower-speed predecessors. An internal version has also been announced, the V-series Smart- modem 9600B(TM). Additionally, an upgrade kit will be available to convert the HAYES 2400 to 9600 baud operation. List prices are $1299 (external), $1199 (internal), and $399 (upgrade kit). A Sysop special discount offer is expected to be offered by HAYES in the near future. The Sysop price will be $595, and will likely be limited to two per Sysop. These modems should be available at the end of July, 1987, according to HAYES. Following is a description of the Smartmodem 9600 EXTERNAL modem: The HAYES V-series 9600 external modem offers fast turnaround, half-duplex V.32 communications at a much lower cost than V.32 full-duplex modems; error- control and forward error-correction; increased throughput with adaptive compression in its error-control mode; and with automatic feature negotiation. A "ping-pong" protocol used at 9600 and 4800 bps incorporates special synchronizing techniques for a fast line turnaround, and simulates full-duplex V.32 operation in terminal or interactive mode, which makes it indistinguishable from full-duplex operation. When performing fast downloads of large data files from mainframes to PCs, or full-screen data transfers where the volume of data in the reverse direction is small (for example: on- line airline reservation scheduling), the ping-pong protocol automatically allocates the direction of activity on the line in proportion to the volume of data that is being transmitted. The built-in error-control provides a reliable means of correcting errors that may occur during the transmission, due to noise on telephone lines. When the V-series Smartmodem 9600 connects to a remote V-series product, it automatic- ally activates its error-control, using an ARQ protocol that automatically requests a re-transmission of any corrupted data. Error-correction in the V-series modems is achieved with Asynchronous Framing Technique (AFT), a protocol based on the LAP-B (Link Access Protocol-Balanced) link level portion of X.25 at 2400 bps and 1200 bps, and an extension of LAP-B at 9600 bps and 4800 bps. At 9600 bps and 4800 bps, the V-series Smartmodem 9600 implements Trellis Encoded/Viterbi Decoding, which is a forward error correcting technique that allows the modem to transmit data accurately, even across noisy telephone lines at very high speeds. When communicating with other V-series modems, the V-series Smartmodem 9600 uses adaptive compression to increase throughput and provide up to twice the normal data transfer, thus lowering both the connect time, and transmission costs. Adaptive compression adjusts itself to the type of data which is being transmitted, and is automatically enabled when the modem is in error-control mode; no user preparation or interaction of the data is necessary at either end of the connection. Feature negotiation makes it possible for the modem to distinguish between V- series hardware and other HAYES modems. It then analyzes all options available (including speed), then automatically selects the combination that maximizes data transmission efficiency. Upon the initial modem handshake, the V-series Smartmodem 9600 has the capability to fall back from 9600 bps to 4800, 2400, 1200 or 300 bps. FEATURES: Benefits: 9600, 4800, 2400, 1200, Provides automatic speed selection on and 0-300 bps transmission initial handshake in Bell and CCITT modes. Makes the highest connection possible. HAYES Standard AT command User control with complete HAYES AT Set expansion Command Set, plus subset of special V-series commands Asynchronous and Transmission flexibility enables com- synchronous transmission munications with a variety of devices through a single modem and a single communications port. Error-control Provides maximum reliability of com- munications with other V-series hard- ware. Especially suited to transmitting program code or important text files or spread sheets. Implementation of the LAP-B link level portion of X.25 or Asyn- chronous Framing Technique (AFT) at 2400 bps and 1200 bps, and extended LAP-B derivative at 9600 bps and 4800 bps, allow point-to-point error-control. Adaptive compression On-line compression increases data throughput in error-control mode, providing up to twice the normal data transfer and lowering both transmission costs and connect time. Automatic feature negotiation Automatically distinguishes between re- mote V-series hardware and other HAYES modems to establish appropriate connec- tion. Analyzes all options (including speed) available and selects combination that maximizes data transmission efficiency. No user interaction is required. Flow-control options RTS/CTS. Transparent XON/XOFF, XON/XOFF (Stop/Start), or none. Storable configuration profiles Stores two user configuration profiles in nonvolatile memory in addition to the factory configuration profile. Stored telephone numbers Stores up to four telephone numbers (36 digits) in nonvolatile memory for asyn- chronous autodial. Designate user profile Designate either of two stored configura- tion profiles as the default to recall when the modem is powered up or reset. View configuration profiles Use modem commands to display the active and stored configuration profiles and any telephone numbers stored in the modem's nonvolatile memory. Call progress monitoring Recognizes dial tone, ringback signal, and busy signal. Enhanced diagnostic testing Loopback tests and modem firmware tests check the modem's firmware ROM and the communication link to diagnose communication problems for quick correction.
