Chapter 1 - Introduction and Description
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 V.34 modem technology on a single board. It is a "full sized" add-on card which supports a high-speed interface up to 115.2K bps per port. This card has multiple on-board Enhanced V.34 (33.6K bps) data/V.17 (14.
Chapter 1 - Introduction and Description 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.
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.
Chapter 1 - Introduction and Description Chapter 3 - Service, Warranty & Technical Support/BBS Chapter 3 provides instructions for getting the MultiModemISI serviced at the factory and warranty information. Instructions are given for downloading firmware upgrades via FlashROM, accessing Multi-Tech's Bulletin Board Service (BBS) and receiving technical support via CompuServe and Internet forums.
