AppendixD: Configuration Methods

Firmware-based Configuration Utility

1.If you are using another operating system, turn on your computer and start your data communications program.

2.The TR (Terminal Ready) LED lights to indicate that your computer is ready to communicate with the TA.

POTS Port Configuration Menu. Select this menu to configure the MTA128S T/NT’s POTS port which includes the ring type, frequency, and pattern.

Help Menu. Select this menu for help on navigating through the MTA128ST/NTmenu system.

Configuration via AT Commands

You can configure the MTA128ST/NT by using AT commands, just as you would configure an analog modem. Use this method if you prefer to work with AT commands or if you have a special requirement not addressed by either of the configuration utilities.

Using AT Commands to Configure the MTA128ST/NT

1.Connect a VT1 00/ANSI-compatible terminal, or a computer that has a communications program that has VT100/ANSI terminal emulation, to the MTA128ST/NT’s serial port.

2.Turn on the MTA128ST/NT. The MTA128ST/NT automatically detects whether an ASCII or ANSI terminal is in use and adjusts accordingly.

3.Start a data communication program and select the COM port where the MTA1 28ST/NT is connected.

4.Referring to your Before Your Start notes, enter the desired AT commands in the terminal window of the data communications program.

5.When you finish making changes, use the &Wcommand to save your new configuration, and to select it to automatically load when the MTA128ST/NT is turned on.

6.Quit the data communications program.
