V-series ULTRA Smartmodem 14400 Mon 09-16-1991 -------------------------------- *** AVAILABLE 4TH QUARTER *** Hayes ULTRA 144 V-series ULTRA Smartmodem 14400 is a high speed, high capability modem that implements the most advanced international and industry standards with CCITT V.32bis for 14.4 Kbps line speed and CCITT V.42bis for 38.4 Kbps throughput. ULTRA 144 delivers unique connectivity to SNA, X.25 and ISDN networks and supports virtually every modem communication application in mainframe, workstation and personal computer environments. Customers using ULTRA 144 receive the maximum 50 percent throughput improvement over 9600 bps in synchronous environments or when transferring compressed data files. ULTRA 144Us X.25 PAD supports four simultaneous communication sessions to packet switched networks and provides transition to ISDN by connecting analog modems to digital ISDN systems through packet switched networks. ULTRA 144 also features Hayes AutoSync for synchronous communciations, MI/MIC for support of PABX and security systems, and CCITT V.25bis for synchronous autodialing. The modem also provides backward compatibility with MNP 2-5, Hayes Adaptive Data Compression, and LAPB error-control to provide a migration path to CCITT V.42 and V.42bis. By supporting Express 96, ULTRA 144 communicates with V-series Smartmodem 9600s, the worldUs largest installed base of proprietary 9600 bps modems. MODULATION CCITT V.32bis - Adopted by the CCITT on 22 February 1991, V.32bis provides high-speed, full duplex communications at 14,400 and 12,000, 9600, 7200, and 4800 bps. V.32bis modulation pushes the capabilities of technology to new levels of complexity so that data communications can further approach the theoretical limits of transmission on telephone lines. Supports V.32bis procedures for fallback to lower speeds during the initial connection, and V.32bis Rate Re-negotiation to allow rapidly fallback to lower speeds and step up to higher speeds based on line conditions. CCITT V.32 - Adopted by the CCITT in October, 1984, this standard is now becoming the mainstream business standard for high speed modems, overtaking CCITT V.22bis. CCITT V.32 provides high-speed, full duplex 9600 and 4800 bps communications. Supports V.32 Automode procedure and EIA/TIA IS-63 for fallback from V.32 to lower speeds. Express 96 - A modulation that enables ULTRA 144 to communicate at 9600 and 4800 bps with Hayes V-series Smartmodem 9600s, the worldUs largest installed base of proprietary 9600 bps modems. Express 96 is a Hayes proprietary modulation that simulates full-duplex 9600 bps operation. (Express 96 was formerly known as Hayes fast turnaround RPing PongS protocol.) International Data Transmission Standards - In addition to CCITT V.32bis (14,400 bps) compliance, ULTRA 144 supports V.32 (9600 and 4800 bps), V.22bis (2400 bps), V.23 (1200/75 and 75/1200 bps), V.22 (1200 bps), and V.21 (300 bps) transmissions. Industry Data Transmission Compatibility - ULTRA 144 also supports communication with 103 (300 bps) and 212A (1200 bps) modems. ERROR CONTROL CCITT V.42 - Supports standardized, point-to-point error-control communications using the CCITT V.42 LAPM (Link Access Procedure for Modems) protocol. CCITT V.42's alternative protocol provides backward compatibility with modems using MNP 2-4. V-series LAPB - ULTRA 144 provides error-control compatibility with the installed base of V-series modems using Link Access Procedure Balanced (LAPB). In addition, LAPB provides link-level error-control for access to Packet Switched Networks using X.32 (Dial X.25). DATA COMPRESSION CCITT V.42bis - CCITT V.42bis international data compression standard for use by modems incorporating the V.42 LAPM error-control standard provides compression capabilities to 4:1 enabling ULTRA 144 to achieve throughput to 38.4 Kbps. Hayes Adaptive Data Compression (ADC) - ULTRA 144 implements ADC with the early installed base of V-series system products to attain compression capability to 2:1 for throughput up to 19.2 Kbps. MNP 5 - ULTRA 144 provides a migration path to V.42bis data compression by supporting backward compatibility with modems using MNP 5 for up to 2:1 compression. TELEPHONE LINE INTERFACE Dial-up Line - Provides pulse or tone dialing out and auto answering for Public Switched Telephone Network (PSTN) operation. PABX and Business Line Support - ULTRA 144 operates in a variety of PABX environments and has selectable features for operation with business telephone lines. Leased Line - Two-wire leased line communication is supported by ULTRA 144. PACKET SWITCHED NETWORK CONNECTIVITY CCITT X.32 Standard - Supports X.32 (Dial X.25) standard for dial-up compatibility with Packet Switched Networks worldwide. Error-Control - Supports either point-to-point or point-to-multi-point communications using X.25 Packet Switched Networks. Triple X PAD - ULTRA 144 provides a Triple-X PAD (Packet Assembler/Disassembler) in the modem by implementing 1988 versions of CCITT X.3, X.28, and X.29. Hayes AutoStream - Supports up to four simultaneous virtual sessions using the Hayes AutoStream protocol to support and manage the sessions. Economical Telephone Network Transition to ISDN - ULTRA 144 supports an X.25 PAD to use X.25 packet switched networks as gateways for connections between analog modems and digital ISDN systems. Smartcom III Communications Software - With Smartcom III communications software, users are not required to learn PAD commands. The program allows easy set up as well as stored configuration for calling up CCITT X.32 (Dial X.25) networks. MODEM CONTROL AND OPERATION Hayes Standard AT Command Set - Full support for this industry standard enables ULTRA 144 to operate with the large installed worldwide base of communications software. Hayes Escape Sequence with Guard Time - Allows the modem to reliably escape from the on-line 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 October 22, 1985. Automatic Feature Negotiation - ULTRA 144 automatically negotiates with other modems to analyze all features available (modulation, error-control, data compression, etc.) to establish the most efficient communications session. This powerful capability is implemented transparently, making ULTRA 144 exceptionally easy to use even though its feature set offers a wide range of capabilities and communications options. Automode - Procedures defined in CCITT Recommendation V.32 that allow modems with both V.32 and V.22bis modulation to reliably interwork with other modems which have either or both of these modulations, at the highest speed in common between the modems. Rate Re-negotiation - Procedures defined in an appendix to CCITT Recommendation V.32bis to allow the modem to change the modulation speed based on the amount of noise present on the telephone line. The modulation speed is decreased as the line worsens and increased as line conditions improve. Automatic Speed Buffering - Allows a V-series modem to provide a fixed speed interface between the V-series product and its DTE (mainframe, mini-computer, or PC). This enables the V-series modem to communicate at varying speeds with other modems while communicating at a fixed interface speed if required by its attached DTE. Flow Control - Works with systems equipped with flow control to manage the interface between the modem and the system to control buffers and preserve data integrity, preventing inadvertent data loss between the modem and the system. MI/MIC - Allows a system such as a PABX or a call back security system to instruct the modem to go off hook and establish a call. CCITT V.25bis - The modem supports CCITT V.25bis asynchronous and synchronous communications when required by a host or an international regulatory agency. The modem can be controlled through an optional command set supporting the CCITT V.25bis international standard for asynchronous and synchronous autodialing. TRANSMISSION MODES Asynchronous Hardware Mode - Supports standard asynchronous communications for dial-up communications with value added networks, on-line services, and personal computers. Synchronous Hardware Mode - The modem supports SDLC, HDLC and Bisync synchronous transmission for connections to mainframes and mini-computers. A PC using a synchronous adapter card is also supported. In addition, the modem supports several methods of synchronous autodialing, including CCITT V.25bis. Hayes AutoSync - ULTRA 144 can use the system's standard asynchronous communications port for synchronous communications, eliminating the additional expense of a synchronous adapter card for SDLC or Bisync. This convenient feature brings both asynchronous and synchronous data transfer capability to your system in one communications device.
