Hayes Smartmodem OPTIMA 28800 V.34/V.FC FAX

Hayes Smartmodem OPTIMA  28800 V.34/V.FC FAX (OPTIMA 288 V.34/V.FC +
FAX) is Hayes award-winning 28,800 bit/s modem that now implements the
ITU-T V.34 standard.  In addition to supporting the ITU-T V.34 standard,
OPTIMA 288 V.34/V.FC + FAX implements the V.Fast Class (V.FC)
technology developed by Hayes and Rockwell to provide an interim
industry standard modulation for 28,800 bit/s communications prior to
the ratification of V.34.  The product will operate at 28,800 bit/s with
Hayes and other vendors' products that implement the V.34 and/or the
V.FC standards.  The product is also fully compatible with the installed
base of V.32bis (14.4 kbit/s), V.32 (9600 bit/s), V.22bis (2400 bit/s),
and V.22 (1200 bit/s) modems.

OPTIMA 288 V.34/V.FC + FAX is a powerful solution for multi-media,
remote access to a LAN, shared modem access from a LAN, and the transfer
of large data files.  Using Hayes superior implementation of V.42bis,
the product transfers data up to 230,400 bit/s using data compression --
the fastest rate available from Hayes over dial-up phone lines.

Through 1 March 1995 Hayes is offering a free upgrade to OPTIMA 288 V.FC
+ FAX users if they purchase an additional OPTIMA 288 V.34/V.FC + FAX
modem.  Customers who do not wish to purchase an additional modem can

Understanding OPTIMA 288 V.34/V.FC + FAX 230,400 bit/s Capability

Hayes Superior Implementation of V.42bis - OPTIMA 288 V.34/V.FC + FAX
modem can achieve throughput up to 230,400 bit/s on highly compressible
files using ITU-T V.42bis.  This increase in the maximum compression,
from 4 times to up to 8 times, is achieved by optimizing the
implementation of V.42bis.  This superior implementation is not
proprietary and will operate with any modem implementing V.42bis.

MODULATION

ITU-T V.34 - The recently ratified ITU-T standard offering modem speeds
up to 28,800 bit/s.  Also provides high-speed, full duplex
communications at speeds ranging from 28,800, 26,400, 24,000, 21,600,
19,200, 16,800, 14,400, 12,000, 9600, 7200, 4800, and 2400 bit/s.

V.FC - An interim industry standard developed by Hayes and Rockwell
offering speeds up to 28,800 bit/s.  This interim industry standard has
an installed base of approximately one million units.  Also provides
high-speed, full duplex communications at 28,800, 26,400, 24,000,
21,600, 19,200, 16,800, and 14,400 bit/s.

ITU-T V.32bis - V.32bis provides high-speed, full duplex communicatons
at 14,400, 12,000, 9600, 7200, and 4800 bit/s.  Supports V.32bis
procedures for fallback to lower speeds during the initial connection,
and V.32bis rate renegotiation during online communications.

ITU-T V.32 - 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.32bis
and V.32 compliance, supports V.22bis (2400 bit/s), V.22 (1200 bit/s),
and V.21 (300 bit/s) transmissions.

Industry Data Transmission Compatibility - Supports communications 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.27ter (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 alternative protocol provides backward
compatibility with modems using MNP 2-4.

DATA COMPRESSION

ITU-T V.42bis - 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.42bis data compression by
supporting backward compatibility with modems using MNP 5 for 2:1 data
compression.

Bi-directional/Uni-directional Optimization - Throughput is optimized
depending on the direction data is transmitted.  During normal file
transfer operation, data thoughput 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 is established (including dialing), or on from
completion of dialing until connection is established.

Modular Connector - Standard RJ-11 telephone jack, with extension jack
for telephone.


MODEM CONTROL AND OPERATION

Advanced Line Probing and Renegotiation - Will renegotiate to the
highest possible transmission speed to compensate for network and phone
line performance.

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 mode.
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).  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.

AutoFAX - 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.32bis that allow modems with V.32bis, V.32, and V.22bis 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.34/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 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 synchronus 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 57,000 bit/s.  Both allow synchronous-mode operation of a
modem connnection 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.
