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.

Understanding OPTIMA 288 V.FC + FAX 230,400 Capability

Hayes Enhanced Implementation of V.42 bis - OPTIMA 288 V.FC + FAX modem
can achieve speeds up to 230,400 bit/s on highly compressible files
using ITU-T V.42 bis.  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.
