4 MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD

Welcome to Multi-Techs new 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

analog calls are detected, they are automatically connected to one of

the four V.90 modems on the ISIHP board. In this way, these hybrid

cards can handle either ISDN calls or analog modem calls. Although

the ISIHP-2S/2U contains four ISDN TA ports and four analog

modem ports, only four ports can be active at any one time (because

only four B-channels are present). See Figure 1-1.

The ISIHP-4S/4U works like the ISIHP-2S/2U but contains four

terminal adapters and eight V.90/K56flex modems. The 4S and 4U

models each accommodate four ISDN BRI lines. The configuration of

modem and TA ports for the 4S and 4U models is shown in Figure 1-

The ISIHP-4SD contains four terminal adapters only (the daughter

card containing the eight modems is absent). Since it accommodates

four ISDN BRI lines (each offering two B-channels), it supports eight

independent digital data connections.

Each terminal adapter appears as two ports to the server PC using the

ISIHP card.

ISIHP cards also support dial-out applications via their modems or

terminal adapters.

The ISIHP-2S/2U card offers eight RAS ports using two Basic Rate

Interface (BRI) ISDN lines; the ISIHP-4S/4U has 16 ports using four

BRI ISDN lines. For the ISIHP-2S/2U, its eight ports allow a server

to accept any combination of analog modem and digital ISDN calls,

making a maximum of four simultaneous independent data

connections. For the ISIHP-4S/4U, its sixteen ports allow a server to

accept any combination of analog modem and digital ISDN calls,

making a maximum of eight simultaneous independent data

connections. This arrangement gives the user the flexibility to

customize the settings of the terminal adapters and modems. The

terminal adapters on the ISIHP-4SD can make eight simultaneous

independent connections.

Introduction

MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD 7

From the perspective of the server PC, the ISIHP-2S/2U is an eight-

port serial card with eight devices permanently attached to the serial

ports (Figure 1-1). The first four ports are the two terminal adapters,

each of which appear as two ports. The remaining four ports are the

four central site modems. The following chart summarizes the

correlation of ports and devices.

From the perspective of the server PC, the ISIHP-4S/4U is an sixteen-

port serial card with sixteen devices permanently attached to the serial

ports (Figure 1-2). The first eight ports are the four terminal adapters,

each of which appear as two ports. The remaining eight ports are the

eight central site modems. The following chart summarizes the

correlation of ports and devices. The ISIHP-4SD contains terminal

adapters only; no modems are present.

This ISIHP Quick Start Guide contains installation instructions and

technical support information. Because its written for audiences with

basic PC skills, step-by-step instructions for such basic operations as

logging in and file editing are not included.

Peripiheral Component Interconnect (PCI)

First developed by companies such as IntelTM, AT&TTM and Digital

Equipment CorporationTM, the Peripheral Component Interconnect

(PCI) bus used by your ISIHP card provides high performance and is

easy to use. Because PCI devices contain registers with the device

information required for configuration, full auto configuration of PCI

Local Bus add-in boards and components is supported. Performance

factors include a bus data path of 64 bits, clock speeds of 66 MHz,

and bandwidth of 264 Mbs.

Communication Protocols for ISIHP Ports

Ports on the ISIHP card can be associated with different protocols, as

follows:

Auto-Protocol. Modem or terminal adapter automatically negotiates

with host to operate using the hosts current protocol.

Central Site Modem. Common designation for analog modems built

into the ISIHP card. These are V.90 modems. For the ISIHP-2S/2U,

the last four modems should be designated as Central-Site modems;

for the ISIHP-4S/4U, the last eight modems should be designated as

Central-Site modems. (See Port/Device table on previous page.)

MultiLink PPP async. This protocol allows the functional bundling

together of three WAN ports so they function as a single high-

bandwidth data pipeline using only one IP address. Bundling occurs

on demand when the needed bandwidth exceeds that available on a

single circuit.

PPP async. (Point-to Point Protocol, asynchronous) Protocol

allowing computers a dial-up connection to the Internet. PPP includes

error detection, data compression and other improvements over Serial

Line Internet Protocol (SLIP) connections.

V.120. Terminal rate adaptation protocols. These apply to ISDN B-

channels when using a V interface. This protocol includes V.110.

X.75. An international standard that allows X.25 packet-switched

networks to communicate with each other. X.75 is a gateway protocol

for interconnection of X.25 public networks.
