Connecting To Power; Connecting To Your Isdn Network Terminator; Connecting To Analog Equipment - Multitech MTA128ST Quick Start Manual

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 switch to ON.
4. Verify operation by observing the LED indicators on the front panel. The LEDs will initially
flash in a self-test pattern. Then the LS LED will remain on. (See LED descriptions in the
on-line User Guide.) If the terminal adapter does not appear to be working, see Chapter 5
in the on-line User Guide for troubleshooting help.
Caution: Only use the power supply shipped with your MTA128ST-USB; any other power
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 AUX jack and ISDN jack 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 the device's modular RJ-11 telephone cord into the RJ-11 AUX connector.
Note: The AUX jack and the ISDN jack on the unit are not interchangeable.
