Chapter 1 - Introduction
1.1 Introduction
Welcome to Multi-Tech’s MultiModemISI Hybrid Series of ISDN BRI server cards. The series consists of eight
models, briefly described in the table below below.

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. The ISIHP-
4SD is 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.
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 ISIHI-2S/2U function
like the ISIHP-2S/2U units but have an ISA-type bus which requires manual setting of the I/O address and the
interrupt request (IRQ).
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 1-2.
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
ISI card. ISIHx cards also support dial-out applications via their modems or terminal adapters.
MultiTech’s ISI Management Software is designed to monitor data traffic and control the modems/TAs of ISIHx
server cards operating in the Windows 2000 Server and Advanced Server OSs. (See the ISI Management
Software User Guide, doc #88301450.)

Chapter 1 - Introduction
1.1.1 ISIHP-2S/2U Serial Card
The ISIHP-2S/2U and ISIHI-2S/2U cards each offers eight RAS ports using two Basic Rate Interface (BRI)
ISDN lines; the ISIHP-4S/4U has 16 ports using four BRI ISDN lines. The eight ports of the 2S/2U models
allow a server to accept any combination of analog modem and digital ISDN calls, making a maximum of four
simultaneous independent data connections (sessions). 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.
From the perspective of the server PC, the ISIHP-2S/2U (or ISIHI-2S/2U) is an eight-port serial card with eight
devices permanently attached to the serial ports (Figure 1-1).

Chapter 1 - Introduction
1.2 Peripiheral Component Interconnect (PCI) for ISIHP Cards
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 32 bits, and clock speeds of 33 MHz.
1.3 Communication Protocols for ISIHP Ports
Ports on the ISIHP card can be associated with different protocols, as follows:
Auto-Protocol Terminal adapter automatically detects and switches to use the protocol of the
client terminal adapter.
Auto-Protocol Callback Same as Auto-Protocol except that it causes the host terminal-adapter to dial
back with the same protocol with which the client dialed in.
Central Site Modem The digitally terminated V.90 modems built into ISIHx series cards (except the
4SD model). 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.)
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.
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.

2.5 Hardware Installation Procedure
1. Before handling the ISIHP card, discharge any static in your body by touching a piece of grounded metal
such as the computer chassis.
2. Carefully remove the ISIHP card from its antistatic bag, handling it only by the mounting bracket and
edges. Do not touch the gold-plated connectors along the bottom edge. (You may want to save packaging
for possible future use.)
3. Visually inspect the ISIHP-2S/2U/4S/4U/4SD. If you have any concerns about the condition of your ISI
card, call Technical Support at [phone].

4. To avoid damaging the ISI card and your PC, make sure your computer and any peripheral equipment
connected to it are turned off. The ISIHP can be installed in a Pentium equivalent PCI bus computer; the
ISIHI can be installed into a Pentium equivalent computer with ISA slots.
5. Remove the cover of your computer as instructed in your computer’s documentation.
6. Locate the unused expansion slot you will be using for your ISI card and remove the slot cover according
to instructions in your computer’s documentation.

14
Chapter 2 - Hardware Installation
7. Install the ISI card in the selected expansion slot in the same manner as any other add-on card according
to your computer’s documentation.
8. Fasten retaining bracket to computer chassis and replace the cover.
9. Connect the ISI to your ISDN telephone wall jack(s) with the provided modular telephone cable.
10. Turn on power to the computer. Now you are ready to install software.

Note: The ISIHP and ISIHI communicate over ISDN lines. If you don’t have a standard modular jack near your
computer, you should install one or have one installed by your telephone company. In the US, installation kits
and adapters are available wherever telephones are sold.
Note: If S/T-interface ISDN network connection cable is used, the ISDN phone cord should be connected
between the ISDN network connection cable and the NT1 device. If the S/T-interface model (ISIHP-2S, -4S, or
4SD, or ISIHI-2S) is used, then the S/T-interface must be connected to the S-interface on the NT1 device.
