Hayes ULTRA 96

ULTRA 96 includes a complete set of the most advanced CCITT standards and 

supports the most frequently-used modem industry technologies.  ULTRA 96 

with CCITT V.32 provides 9600 bps modulation enhanced with CCITT V.42 

error-control and V.42bis data compression for throughput up to 38.4 Kbps. 

 

Offering 16 times the speed of 2400 bps, ULTRA 96 provides unique high 

performance features that are not found as a complete offering in any 

other product.  These unique features include Hayes AutoSync, Express 96 

(formerly known as Hayes fast turnaround "Ping Pong" protocol), CCITT X.32 

(Dial X.25) with Hayes AutoStream, MI/MIC, 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 96 will communicate with the installed base of V-series 

Smartmodem 9600 modems.

MODULATION

CCITT V.32 - Provides high-speed 9600 and 4800 bps communications using 

CCITT V.32 modulation. ULTRA 96 implements Trellis Encoding/Viterbi 

Decoding, a V.32 forward error correcting technique which allows the modem 

to transmit data accurately at high speeds, even across noisy telephone 

lines.  Supports V.32 Automode definition for fallback from V.32 to lower 

speeds.

Express 96 - A modulation that enables ULTRA 96 to communicate at 9600 

and 4800 bps with the installed base of Hayes V-series Smartmodem 9600s.  

Express 96 is a Hayes proprietary modulation that simulates full-duplex 

9600 bps operation.  (Express 96 was formerly known as Hayes fast 

turnaround "Ping Pong" protocol.)

International Data Transmission Standards - In addition to CCITT V.32 

(9600 and 4800 bps) compliance, ULTRA 96 also supports 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 96 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 96 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 96 to achieve throughput to

38.4 Kbps. 

Hayes Adaptive Data Compression (ADC) - ULTRA 96 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 96 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 96 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 96.

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 96 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. 

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 96 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 96 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 96 exceptionally easy to use even though its feature set offers a 

wide range of capabilities and communications options.

Automode - Procedures defined in an appendix to 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.

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 96 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.
