ISI3334/4 Hardware/Driver Installation Manual
1.1 Introduction
Welcome to the world of data communications. You have acquired
one of the finest Intelligent Serial Interface cards available today, the
MultiModemISI. The MultiModemISI integrates ISI mutiport and
Enhanced
sized" add-on card which supports a high-speed interface up to
115.2K bps per port. This card has multiple on-board
(33.6K bps) data/V.17 (14.4K bps) fax modems providing high speed
buffering for multiple serial ports.
This Owner’s Manual contains product information specific to the
modem aspect of this card (e.g., AT Commands and S-Registers).
We recommend referring to your
Installation Manual
installation procedures.

for hardware and operating system(s) driver
1.2 Modem Features
Enhanced
V.34
Your MultiModemISI meets the proposed
standard for data signalling rates as high as 33.6/31.2K bps fullduplex mode, and supports and is compatible with those features,
including EIA extended Automode, adaptive line probing, automatic
symbol rate and carrier frequency during start-up, and retrain and
rate renegotiation (in 2400 bps increments).
Your MultiModemISI features CCITT V.42 error correction and
V.42bis data compression, providing 100% error-free data
transmission. V.42 error correction incorporates MNP Classes 3
and 4, and LAP-M. You may select V.42bis data compression for 41 throughput, or MNP Class 5 for 2-1 throughput.
Your MultiModemISI offers interactive automatic dialing, as well as
Command Mode option configuration. You may store up to ten
command line/telephone numbers, of up to 60 characters each, in
the MultiModemISI’s nonvolatile memory.
The MultiModemISI pulse or tone dials, and recognizes dial tones
and busy signals for reliable call-progress detection. The
MultiModemISI can detect AT&T calling card tones. It is FCCRegistered for connection to telephone networks without any Data
Access Arrangements (DAA’s).

Your MultiModemISI also features Remote Configuration which
permits you to assist users at remote sites, saving you the time and
trouble of site visits and preventing misinterpretation of configuration
instructions.
1.3 Fax Features
Your MultiModemISI meets the CCITT V.17 standard for sending
and receiving faxes. When linked to a compatible fax machine or
modem, it can transmit faxes at 14.4 K bps. It also meets the
CCITT’s Group 3 Designation for sending and receiving faxes at
9600 bps; and Group 2 Designation for sending and receiving faxes
at 4800 bps. The MultiModemISI is also downward-compatible to
speeds as low as 300 bps, so it can send and receive faxes with
virtually any fax machine in the world.
1.4 Product Description
The MultiModemISI is ideally suited to use in PC networks
environments because it provides an integrated hardware solution
for remote access for both Windows NT and Novell-based LANs. In
particular, to ensure smooth Novell network integration, the
MultiModemISI ships with NetWare Loadable Module for NetWare
ConnectTM communication servers that enable it to support state-ofthe-art features such as remote dialing and modem pooling. And,
the MultiModemISI easily integrates into the Windows NT platform
since it fully supports Microsoft's Remote Access Server software.
This allows it to comfortably operate with popular network protocols
such as TCP/IP and NetBIOS. The MultiModemISI ships with drivers
for other multiuser operating systems such as SCO® UNIX®, SCO
XenixTM, and SCO UNIXWare®.
Chapter 1 - Introduction and Description
The MultiModemISI includes an Intel 16 MHz 80186 proccesor and
256K of RAM that work dynamically to allocate resources to the
most active modems.
Simple to install, the MultiModemISI can be used to add multiport,
Enhanced
as easily as plugging in an expansion card, running the driver
software, and connecting the phone lines.

ISI3334/4 Hardware/Driver Installation Manual
Network managers have the option of starting with the base four
modem configuration (model #ISI334/4), and then adding four more
modems at a later date without having to use another PC expansion
slot.
This is accomplished by pairing one MultiModemISI with an auxiliary
module (model #ISI3334/EC) interfacing both with on-board
connectors.
Some MultiModemISI on-board components include one jumper
block for activating the number of ports in increments of 4 or 8. One
bank of 8 DIP-Switches for I/O address selection and one IRQ
jumper block, that control both the MultiModemISI and auxiliary
module I/O addressing and IRQ values.
When installing a single MultiModemISI in your PC, the installation
scripts create 8 devices. The first 4 devices are active, however, the
4 devices on the auxiliary module are not active until connected to
the MultiModemISI.
1.5 How to Use This Manual
This manual is divided into three chapters and three appendices.
The information contained in each chapter and appendix is as
follows:
Chapter 1 - Introduction and Description
Chapter 1 begins with a short product introduction and description;
followed by a guide (which you are now reading) to the use of this
manual.
Chapter 2- "AT" Commands and S-Registers
This chapter focuses on the use of “AT” Commands and SRegisters. Chapter 2 provides basic steps for originating and
answering calls and a summary of commands that enable the user
to establish, read, and modify parameters in addition to dialing.
Information on setting up high speed communication ports in SCO
UNIX and UNIXWare environments is also provided in this chapter.
