Welcome to Multi-Techs 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 ISIHP4SD, 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; Umodels 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
Induction
4 MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD
Welcome and Product Description
Introduction
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-
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
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
From the perspective of the server PC, the ISIHP-2S/2U is an eightport 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 sixteenport 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 its 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.

Introduction
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 hosts 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 highbandwidth 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 Bchannels 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.

Safety Warnings
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jacks are
specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
Avoid using a telephone (other than cordless type) during an
electrical storm. There may be a remote risk of electrical shock from
lightning.
12 MultiModemISI Hybrid Series, ISIHP-2S/2U/4S/4U/4SD
Hardware Installation
Do not use the telephone to report a gas leak in the vicinity of that
leak.
Ports that are connected to other apparatus are defined as SELV.
To ensure conformity to EN 41003, ensure that these ports are
connected only to the same type on the other apparatus.
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 goldplated 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. The 2S and 4SD
models have only one daughter card, whereas the others have two.
If you have any concerns about the condition of your ISIHP unit,
call Technical Support at (612) 717-5863.

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
