Owner’s Manual
6 MT5634ZPX-PCI
ongratulations on your purchase of one of the finest internal
C
data/fax/voice modems available todaythe MultiModemZPX-PCI
from Multi-Tech Systems.
The MultiModemZPX-PCI is an internal, half-length, fax modem card
that can be plugged into any PCI slot. Your MultiModemZDX-PCI
incorporates V.90/K56flexTM 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 detect AT&T calling card tones. It is FCC-
Registered for connection to telephone networks without any Data
Access Arrangements (DAAs).
The MultiModemZPX-PCI is a full-featured internal data/fax/voice
modem designed for Pentium computers in Windows Plug and PlayTM
environments.
This owners manual will help you to install, configure, use, and
troubleshoot your modem.

MT5634ZPX-PCI 9
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
 New 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
 New 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 startup time.
Auto-rate Speeds
Auto-rate speeds to 50,666 Kbps are supported for downstream
transfers.

Configuring the MultiModem ZPX-PCI
Windows 95 Plug and Play
Unlike an external modem, the MultiModemZPX-PCI contains its own
serial port. When Windows 95 detects the MultiModemZPX-PCI, it
assigns the next available COM port number to it. Since COM1
through COM4 are standard serial ports in Windows computers,
Windows 95 typically assigns COM5 to the modems serial port.
Windows 95 also assigns the a port address and 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.
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 (can be purchased at a
local PC retail store).
2. Place one end of a 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 using the bundled Trio software.
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). Feedback occurs if the microphones are
too close to each other. Make sure speakers are amplified with
power source being either a battery or AC outlet.
4. Place microphone and speakers far enough apart from each other
to eliminate feedback. Plug connector of both microphones into
the MIC IN jack of the SoundCard and the MultiModemZPX-PCI.

2 Installation
MT5634ZPX-PCI 17
Installing the MultiModemZPX-PCI
