Welcome to Multi-Tech’snew MultiModemISI Hybrid Series,

models ISIHP-2S/2U and ISIHP-4S/4U, multiport hybrid ISDN cards that can be plugged into any PCI slot for applications that involve ISDN or modem calls over ISDN BRI lines. When the ISIHP 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. This manual also describes the ISIHP- 4SD, a serial interface card equipped with four terminal adapters only (no analog modems are present). The ISIHP-4SD is otherwise like the ISIHP-4S/4U models. S-models use the ISDN “S” interface; U- models use the ISDN “U” interface.

The ISIHP-2S/2U contains two terminal adapters and four V.90/ K56flex modems. The ISIHP-2S/2U uses two ISDN BRI lines (each offering two B-channels) to connect to the telco and these connect to its two built-in terminal adapters. In addition to handling ISDN calls, each terminal adapter can detect analog modem and fax calls. When
