Turn on the TA by sliding the power switch to ON and verify operation by observing the LEDs on the front
panel. The LEDs first flash in a self-test pattern. Then the LS LED remains on. If the TA does not appear to
be working, Refer to Chapter 5 for troubleshooting help.
Connect the TA to Your PC (RS-232 Connection)
Plug one end of the RS-232 serial cable into the RS-232 connector on the modem, and plug the other end
into a serial port connector on your computer, such as COM1 or COM2. You supply the RS-232 cable.
Connecting to your ISDN Network Terminator
If you need a longer cable than the one provided with your TA, select a cable 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 3, 4, 5, and 6).
Plug one end of the cable into the ISDN jack on the TA and the other end into the jack on your network
terminator (MTA128ST) or U-interface (MTA128NT).
Note:
The PHONE jack and ISDN jack are not interchangeable.
(Optional) Connecting to Analog Equipment
You can connect an analog device such as an analog telephone, modem or fax machine to the TA. Simply
put the device’s module telephone cable into the PHONE Jack (RJ1 1) on the TA.
Note:
The PHONE jack and the IDSN jack on the TA are not interchangeable.
