Introduction

MultiModemISI Hybrid Server Cards, ISIHP & ISIHI Series 7

Welcome to Multi-Techs MultiModemISI Hybrid Series of

ISDN BRI server cards. The series consists of eight models:

The 2S/2U and 4S/4U models are all multiport hybrid ISDN cards that

can be plugged into a server expansion slot (PCI or ISA, as listed) for

applications that involve ISDN or modem calls over ISDN BRI lines.

When the ISI card is used with Remote Access Servers (RAS), remote

users can call in using either modems or ISDN terminal adapters

(TAs). For V.90 modem calls, a 56kbps download speed can be

achieved without the expense of T1, E1, or ISDN PRI lines. S-models

use the ISDN S interface; U-models use the ISDN U interface.

This manual also describes the ISIHP-1S and the ISIHP-4SD cards.

The ISIHP-1S is a revised version of the ISIHP-2S card that has been

altered to accept one ISDN Basic Rate Interface line rather than two.
