MultiModemISDN User Guide
Introduction
Welcome to the world of data communications. Y ou hav e acquired one of the finest ISDN terminal
adapters (T A) a vailable toda y from one of America’ s oldest and most respected modem manufacturers:
Multi-Tech Systems, Inc. This user guide will help y ou install, configure , test and use y our terminal
adapter.
Product Description
The MTA128ST-USB is a desktop terminal adapter with an ST port used for connection to an ISDN
network, a USB port for connection to a PC or laptop, and an analog port to connect to a telephone,
modem, or fax machine. It ships with a softw are configuration utility for Windo ws® 2000 and Windo ws
98/95. In addition, the MTA128ST-USB accepts AT commands that enable it to use the same
communications software as an analog modem.
Figure 1-1: MT A128ST-USB (Front View)
The MTA128ST-USB is compatible with the popular EuroISDN switch protocol, it communicates using
ISDN BRI (2B+D) service, which provides up to 128 Kbps data and voice communications, and it
automatically detects whether an incoming call is voice or data and handles it appropriately.
Universal Serial Bus (USB)
Universal Serial Bus (USB), defined by a consortium of industry leaders, permits connection of
multiple low-speed and medium speed computer peripheral devices such as telephones, modems,
printers, keyboards, mice, and scanners; all from a single personal computer port. The specification,
based on open architecture has become a standard feature in new desktop and notebook computers.

USB devices without restarting or reconfiguring your PC
• Compatibility with U.S. NI-1, AT&T 5ESS, and DMS-100 switch protocols
• Compatibility with V.110*, V.120, ML-PPP, and X.75 protocols
• ISDN BRI (2B+D) and analog ports
• USB port (T ype B)
• Support of PPP (Point-to-Point Protocol) f or high speed ISDN connections
• Tone detection to allow use of a standard telephone f or ISDN line access (an ISDN telephone
is not required)
• Automatic detection of incoming calls as voice or data
• Windows 2000 and Windows 98/95 software utility f or easy ISDN line configuration
• AT commands, S-registers , and result codes
• Ability to use the same communications software as analog modems

Assembling the MTA128ST-USB
The only assembly required is to mount the feet on the bottom of your unit (See Figure 2-2). Peel the
four self-adhesive plastic feet off the backing strip and press them into the recesses on the bottom of
the MT A128ST-USB.
Figure 2-2. Mounting the Feet
Connecting the MTA128ST-USB to Your System
Place the MTA128ST-USB terminal adapter in a convenient location. In a typical configuration, y ou will
need to connect your MTA128ST-USB to your computer’s USB port, to its own power supply, to the
ISDN network terminator, and to any optional analog equipment you are using (e.g., a telephone). Each
cabling procedure is shown in Figure 2-3.

Chapter 2 - Hardware Installation
Connecting to Your Computer
1. Plug the 4-pin flat end (Type A) into a USB port connector on your computer or laptop.
Note: Do NO T plug the “D-shaped” end (Type B) of the USB cable into the USB connector on the
back panel of the MTA128ST -USB at this time. You will be directed to make the connection when
installing the software drivers.
Connecting to Power
1. Plug the power supply into the unit’ s POWER connector .
2. Plug the power supply into a live AC outlet.
3. Turn on the unit by sliding the power s witch to ON.
4. V erify operation by observing the LED indicators on the front panel. The LEDs will initially flash in
a self-test pattern, then the LS LED remains on. (See LED descriptions on the next page.) If the
terminal adapter does not appear to be working, see Chapter 5 for troubleshooting help.
Caution: Only use the power supply shipped with your MTA128ST -USB; any other pow er supply
could damage the unit and void its warranty.
Connecting to Your ISDN Network Terminator
1. If you need a longer line cord than the RJ-45 line cord provided with your MTA128ST-USB, select a
cord that is wired straight through (pin 1 to pin 1; pin 2 to pin 2, etc.) with at least the middle four
pins connected (pins 2, 3, 4, and 5).
2. Plug one end of the provided RJ-45 S/T line cord into the ISDN jack on the MTA128ST -USB and
the other end into the S/T jack on your network terminator.
Note: The A UX jack and ISDN jac k are not interchangeable.
Connecting to Analog Equipment
You can connect an analog device such as an analog telephone, modem, or fax machine to the unit.
Simply plug a modular RJ-11 telephone cord into the RJ-11 AUX connector .
Note: The A UX jack and the ISDN jack on the unit are not interchangeab le.
