Introduction
Congratulations on your purchase of one of the finest internal data/fax/voice modems
available today - the MultiModemZPX™from Multi-Tech Systems.
Product Description
One Modem, Worldwide Use. The MultiModemZPX MT5634ZPX-PCI is designed for
global applications with approvals in more than 22 countries. This means one modem
can ship around the world. The global modem is ideal for businesses with global
operations that want to standardize on one modem and are looking to simplify the
ordering process. Go to www.multitech.com/ to see a complete list of all the countries
for which this modem has approvals.
The MultiModemZPX-PCI is an internal, half-length, fax modem card that can be
plugged into any PCI slot. Your MultiModemZPX-PCI incorporates
V.90/K56flex
TM
modem technology, which enables Internet connections at data rates up to 56 Kbps
over standard telephone lines. V.90/K56flex technology is able to propel data
downstream from the Internet to your computer at speeds of up to 56 Kbps because
data is digitally encoded instead of modulated. Upstream transmission, mostly
keystroke and mouse commands from your computer to the central site, continues to
flow at the conventional data rate of 33.6 Kbps.
Note: Though this modem is capable of 56 Kbps download performance, line impairments,
public telephone infrastructure, and other external technological factors currently prevent
maximum 56 Kbps connections.
Your MultiModemZPX-PCI offers interactive automatic dialing, as well as command
mode option configuration. You can store two command line/telephone numbers, of up
to 40 characters each, in the modem’s nonvolatile memory. The modem pulse or tone
dials and recognizes dial tones and busy signals for reliable call-progress detection. The
modem can detectAT&T calling card tones. It is FCC-Registered for connection to
telephone networks without any DataAccess Arrangements (DAAs).
The MultiModemZPX-PCI is a full-featured internal data/fax/voice modem designed for
Pentium computers in Windows Plug and PlayTM environments.
Peripheral 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
MT5634ZPX-PCI 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.

Limited Warranty 10 years
V.90 Support/Functions
V.90 is the ITU designation for what formerly was called V.pcm. V.90 replaces K56flex
and other proprietary solutions for PCM connections. Dual-mode client modem code will
be important until all central-site digital modems are upgraded to V.90 and all
interoperability problems are resolved. Until that time, the Dual-mode client code
provides reliable connections in K56flex mode to the central-site modems currently
deployed.
V.90 functions/features include:
•V.90/K56flex A-law and µ-law support
•Downstream data rates (S-Register S38)
•Optional V.8bis sequence
•V.90 Mode Selection (S-Register S109) support
•Auto-rate speeds to 50,666 (downstream) support
•Automatic adapting to digital loss and robbed-bit signaling
•V.90 rate result codes
Downstream Rates
Where K56flex provided rates of 32,000 to 56,000 in 2,000 bps increments, V.90
provides rates of 28,000 to 56,000 bps in increments of 1,333 bps.
Upstream Data Rates
Upstream V.90 data rates are 4800 to 33600 bps in 2400 bps increments.
Optional V.8bis Sequence
The V.8bis sequence that precedes K56flex connections is optional for V.90. Dual-mode
servers indicate this capability using V.8bis. Dual-mode clients complete the V.8bis
exchange and then proceed to either the K56flex mode or V.90 mode. V.90-only clients
can skip the V.8bis exchange as a way to shorten the start-up time.
Auto-rate Speeds
Auto-rate speeds to 50,666 Kbps are supported for downstream transfers.
Digital Loss and Robbed-bit Signaling Auto Adapt
The modem automatically adapts to digital loss and robbed-bit signaling on a PSTN
connection.

Sound Card Considerations
If you want speakerphone functions and the ability to record sound or .WAV files through
the sound card at the same time, you need:
•Two stereo PC microphones
•One stereo male-to-male patch cord
•One sound card and optional speakers
To connect a third party sound card:
1. Obtain a stereo male-to-male patch cord at a local PC retail store.
2. Place one end of the stereo male-to-male patch cord into the LINE OUT jack of the
MultiModemZPX-PCI and the other end into the LINE IN jack of the sound card. This
allows you to hear the activity of the modem whether it is originating or answering a
call, or playing a recorded message.
3. Place the stereo microphones (do not use mono microphones) far enough apart
from each other to eliminate feedback (e.g., one on each side of the monitor). Make
sure speakers are amplified with a power source (either a battery or electrical
source). Plug the connector of both microphones into the MIC IN jack of the Sound
Card and the MT5634ZPX-PCI.

Changing your Windows 95/98 COM port assignment
Unlike an external modem, the MT5634ZPX-PCI contains its own serial port. When
Windows detects the MultiModem adapter, it assigns the next available COM port to it.
Since COM1 through COM4 are standard serial ports in Windows computers,
Windows 95/98 typically assigns COM5 to the modem’s serial port.
If Windows assigns the modem to a COM port higher than 4, then certain legacy software
applications will not recognize the modem. To correct this situation, Multi-Tech Systems
provides two additional driver files on the System CD which may be used to reassign the
modem to either COM3 or COM4. To reassign the COM port:
1. Insert the MT5634ZPX-PCI System CD into your computer’s CD-ROM drive.
2. Click Start | Settings | Control Panel. Double click the System icon.
3. Select the Device Manager tab and double-click the Modem icon.
4. Select the MT5634ZPX-PCI and double-click to bring up the Properties sheet.
5. Select the Driver tab. Click the Update Driver button and follow the Update Device
Driver Wizard prompts. The Wizard requests you to specify the path of the new
driver. If you’d like to reassign your modem to COM3, type
D:\COM-3\pcicom3.inf (where D: is the drive letter associated with your computer’s
CD-ROM drive). If you want to reassign your modem to COM4, type
D:\COM-4\pcicom4.inf and continue with the Wizard instructions.
6. When the Wizard completes its installation, your modem should be reassigned to the
new COM port.
Verifying the Windows 95/98 Configuration
Windows also assigns the interrupt request (IRQ) number. Because the number of
IRQs is limited, a computer with several accessories may not have an available IRQ
for your new modem. In that case, you may have to decide which of your other
accessories you can modify or do without.
Be aware that resource settings should be changed only by users with expert knowledge
of computer hardware and hardware configurations.
Note: Changing resource settings improperly can disable your hardware and can
cause your computer to malfunction or be inoperable.
Use the following procedure to check the assignments Windows has made for your
modem:
1. Click Start | Settings | Control Panel. Double-click the System icon.
2. When the System Properties dialog box displays, click the Device Manager tab. A
list of device types appears.
3. Double-click Modem to display a list of modems installed in your computer.
4. Double-click Multi-Tech MT5634ZPX-PCI. The Modem Properties dialog box
displays.
5. Click the Resources tab and note the Conflicting Device list. If there is a conflict
between your modem and another device in your computer, the information appears
