Hayes Smartmodem OPTIMA 28800 V.FC FAX Hayes Smartmodem OPTIMA 28800 V.FC FAX (OPTIMA 288 V.FC + FAX) is a powerful solution for multi-media, remote node access to a LAN, shared modem access from a LAN, and the transfer of large data files. The product transfers data up to 230,400 bit/s using data compression -- the fastest rate available from Hayes over dial-up phone lines. OPTIMA 288 V.FC + FAX implements V.Fast Class (V.FC) technology developed by Hayes and Rockwell to provide an industry pre-standard modulation for 28,800 bit/s communications. The product will operate at 28,800 bit/s with future Hayes products implementing the V.34 (V.Fast) standard once it is approved; however, Hayes will provide an upgrade for those customers who purchase an OPTIMA 288 V.FC + FAX and later want to upgrade to the V.34 standard. The product is also fully compatible with the installed base of V.32 bis (14.4 kbit/s), V.32 (9600 bit/s) and V.22 bis (2400 bit/s) modems. OPTIMA 288 V.FC + FAX supports asynchronous and synchronous communications, as well as Hayes AutoSync 2 which allows the system's asynchronous communications port to communicate synchronously when used with AutoSync software. The product also comes with Smartcom for Windows LE and Windows FAX communications software.

This increase in the expected compression, from 4 times to 8 times, is achieved by optimizing the implementation of V.42 bis and by providing enhanced technology in the product to run at 230,400 bit/s. This enhanced performance is not proprietary and will operate with any modem implementing V.42 bis. OPTIMA 288 V.FC + FAX will go as fast as the other modem will go. Understanding the Modem Numbers V.32 9600 + data compression = 38,400 bit/s V.32 bis 14,400 + data compression = 57,600 bit/s V.FC 28,800 + data compression = 115, 200 bit/s Hayes OPTIMA 288 + Hayes enhanced implementation of V.42 bis = 230,400 bit/s MODULATION V.FC - An industry pre-standard developed by Hayes and Rockwell offering speeds up to 28.8 kbit/s. This industry pre-standard is backed by over 125 modem manufacturers. Also provides high-speed, full duplex communications at 28,800, 26,400, 24,000, 21,600, 19,200, 16,800, 14,400, and 12,000 bit/s. ITU-T V.32 bis - V.32 bis provides high-speed, full duplex communications at 14,400, 12,000, 9600, 7200, and 4800 bit/s. Supports V.32 bis procedures for fallback to lower speeds during the initial connection, and V.32 bis rate renegotiation to allow rapid fallback to lower speeds during online communications. ITU-T V.32 - This standard is the mainstream business standard for high speed modems. Provides high-speed, full duplex communications at 9600 and 4800 bit/s. Supports V.32 Automode procedure and EIA/TIA IS-63 for fallback to lower speeds. International Data Transmission Standards - In addition to ITU-T V.32 bis and V.32 compliance, supports V.22 bis (2400 bit/s), V.22 (1200 bit/s), and V.21 (300 bit/s) transmissions. Industry Data Transmission Compatibility - Supports communication with industry standard 103 (300 bit/s) and 212A (1200 bit/s) modems. ITU-T GROUP 3 Fax Standards - Supports V.17 (14,400, 12,000, 9600, 7200 bit/s), V.29 (9600 and 7200 bit/s), V.27 ter (4800 and 2400 bit/s), and V.21 channel 2 (300 bit/s). ERROR-CONTROL ITU-T V.42 - Supports standardized, point-to-point error-control communications using the ITU-T V.42 LAPM (Link Access Procedure for Modems) protocol. ITU-T V.42's alternative protocol provides backward compatibility with modems using MNP 2-4. DATA COMPRESSION ITU-T V.42 bis - ITU-T V.42 bis international data compression standard for use by modems incorporating the V.42 LAPM error-control standard provides compression capabilities enabling throughput to 230,400 bit/s. MNP 5 - Provides a migration path to V.42 bis data compression by supporting backward compatibility with modems using MNP 5 for 2:1 compression. Bi-directional/Uni-directional Optimization - Throughput is optimized depending on the direction data is transmitted. During normal file transfer operation, data throughput is maximized since the transfers occur in one direction. TELEPHONE LINE INTERFACE Dial-up Line - Provides pulse or tone dialing out and auto-answering for Public Switched Telephone Network (PSTN) operation. Dial Modifiers - Provides the ability to support special residential and commercial PABX features such as pause, pulse and tone dialing, wait for second dial tone, wait for quiet answer, bong tone and hook flash. Call Progress Monitoring - Provides information on the progress of a call. Result code messages notify the user when dial tone, busy signals, and carrier signals are detected, when connections are made and when commands are accepted. Monitor Speaker - Includes audio speaker for monitoring call progress. Speaker volume can be set to three levels under software control. Speaker can be set by software control to be always off, always on, on until connection established (including dialing), or on from completion of dialing until connection established. Modular Connector - Standard RJ-11 telephone jack, with extension jack for telephone. MODEM CONTROL AND OPERATION Hayes Standard AT Command Set - Full support for this industry standard enables the product to operate with the large installed worldwide base of communications software. Asynchronous Facsimile DCE Command Set - Controls modems which are compatible with the "Class 1" fax modem command set. A user configures the software through simple, on-screen selections which are then translated into the appropriate commands that are issued to the modem. Users can make maximum use of advanced fax modem features without needing to learn specific AT Commands. Hayes Patented Improved Escape Sequence with Guard Time Mechanism - Patented technology allows the product to reliably escape from the online mode of operation (receiving/transmitting data) to the command mode (interpreting the Hayes Standard AT Command Set) without being accidentally triggered by transmitted data. U.S. Patent 4,549,302 was granted to Hayes on 22 October 1985 and Canadian Patents 1,186,080 and 1,186,081 were granted on 23 April 1985. Nonvolatile Storage of Phone Numbers and Configuration Profiles - The product stores up to four telephone numbers (36 digits each) in nonvolatile memory. The product also stores two user configuration profiles in nonvolatile memory in addition to factory configuration profile. Automatic Feature Negotiation - Automatically negotiates with other modems, fax machines, and data + fax modems to analyze key features (modulation, error-control, data compression, etc.) to establish the most efficient communications session. This powerful capability is implemented transparently, making the product exceptionally easy to use even though its feature set offers a wide range of capabilities and communications options. Automatic Configuration Support - Allows software to automatically determine the modem capabilities and feature set and to configure the software to support those capabilities. Fall Back/Step Up - Slows transmission if phone line quality deteriorates and returns to original higher speed as line quality improves. Automatic Data/Fax Discrimination - During handshake the modem looks for calling tone, and if not there, switches to data mode. Automode - Procedures defined in an appendix to ITU-T Recommendation V.32 bis that allow modems with V.32 bis, V.32 and V.22 bis modulation to reliably interwork with other modems which have any or all of these modulations, at the highest speed in common between the products. Also in V.FC mode it will work with other modems supporting V.FC modulation to connect at the highest possible speed. Automatic Speed Buffering - Enables the product to communicate at varying speeds with other modems, including non-error-control modems, while communicating at a fixed interface speed if required by its attached DTE (mainframe, mini-computer or PC). Flow Control - Supports three types of flow control: RTS/CTS (using hardware circuits 106/133), XON/XOFF, and Transparent XON/XOFF. Transparent flow control, when used with compatible software, permits the transfer of binary files with any protocol while using XON/XOFF flow control, on systems which do not support RTS/CTS flow control. Includes the capability for software to test the modem cable to determine whether or not RTS/CTS flow control can be used. DATA TRANSMISSION MODES Asynchronous Hardware Mode - Supports standard asynchronous communications for dial-up access to value added networks, online services, personal computers, minicomputers and mainframes. Synchronous Hardware Mode - Supports SDLC, HDLC and Bisync synchronous transmission for connections to mainframes and minicomputers. A PC using a synchronous adapter card is also supported. Hayes AutoSync - Uses the system's standard asynchronous communications port for synchronous communications, eliminating the additional expense of a synchronous adapter card for SDLC, HDLC or Bisync when used with AutoSync or application software. This convenient feature brings both asynchronous and synchronous data transfer capability to your system in one communications device and provides substantial savings over other methods. Hayes AutoSync 2 - Eliminates the requirement of precise control signal timing required by the original AutoSync. Precise control signal timing caused the original AutoSync to be much more difficult to implement at speeds above 57,600. Both allow synchronous-mode operation of a modem connection to an ordinary asynchronous serial card. AutoSync 2 allows reliable operation at high communication speeds above 14.4 kbit/s with multitasking operating systems, with intelligent serial ports and LAN-connected modems.
