V-series Smartmodem 9600
 
Hayes V-series Smartmodem 9600 is a cost effective solution for high
speed communications.  The modem provides advanced error-control and 
data compression features that increase the speed and reliability of 
telecommunications across dial-up lines.  Offering ten times the 
speed of 2400 bps, V-series Smartmodem 9600 supports Express 96 
(formerly known as Hayes fast turnaround "Ping Pong" protocol) to 
provide data throughput of 20 - 25 Kbps (depending on the file) when 
the PC port speed is set to 38.4 Kbps.

V-series Smartmodem 9600 provides the advanced features of ULTRA 96, but 
supports Express 96, a Hayes proprietary modulation that simulates 
full-duplex 9600 bps operation, instead of CCITT V.32.  The modem 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, CCITT X.32 (Dial X.25) with Hayes AutoStream, MI/MIC, and 
backward compatibility with MNP( 2-5, Hayes Adaptive Data Compression, and 
LAPB to provide a migration path to CCITT V.42 and V.42bis.  

MODULATION
  
International Data Transmission Standards - Supports CCITT V.22bis (2400 
bps) and CCITT V.22 (1200 bps) transmissions.   

Industry Data Transmission Compatibility - Supports communication with 
103 (300 bps) and 212A (1200 bps) modems.

Express 96 - A Hayes proprietary modulation that simulates full-duplex 
9600 bps operation when communicating at 9600 bps to other V-series 
Smartmodem 9600 or ULTRA 96 modems. 

ERROR-CONTROL
 
CCITT V.42 - Provides 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 - The original error-control protocol used in the V-series 
Smartmodem 9600 was based on CCITT X.32 (Dial X.25) specifications.  All
V-series Smartmodem 9600s support LAPB which provides link-level 
error-control in compliance with global standards.  
 
DATA COMPRESSION

CCITT V.42bis - CCITT V.42bis international data compression standard 
provides compression capabilities up to 4:1, enabling V-series Smartmodem 
9600 to achieve throughput up to 20 - 25 Kbps. 
                                                                
Hayes Adaptive Data Compression (ADC) - V-series Smartmodem 9600 
implements ADC to provide compatibility with the installed base of 
original V-series system products to attain compression capabilities up to 
2:1 for throughput up to 19.2 Kbps.  Original V-series system products 
support this compression.

MNP 5 - Supports backward compatibility with modems using MNP 5 for up to 
2:1 compression.  

TELEPHONE LINE INTERFACE

Dial-up Line - Supports pulse or tone generated dial out or auto answer
for Public Switched Telephone Network (PSTN).
 
PABX and Business Line Support - V-series Smartmodem 9600 operates in a 
variety of PABX environments and has selectable features for operation in 
business environments.

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-multipoint 
communications using X.25 Packet Switched Networks.
 
Triple X PAD - V-series Smartmodem 9600 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 V-series Smartmodem 9600 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 -  V-series Smartmodem 9600 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 V-series Smartmodem 9600 exceptionally easy to use 
even though its feature set offers a wide range of capabilities and 
communications options.

Automatic Speed Buffering - Allows V-series Smartmodem 9600 to provide a 
fixed speed interface between the V-series product and its DTE (mainframe, 
mini-computer, or PC).  This enables the V-series
Smartmodem 9600 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.

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.  

Hayes AutoSync -  V-series Smartmodem 9600 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.
