Configuration

Run the ISDN MTA128ST-USB configuration utility for North American customized ISDN settings.
Note: For Europe, run the configuration utility to customize the settings of the terminal
adapter such as configuring Multiple Subscriber Numbers (MSNs).
Configure the unit to match your ISDN service and the remote terminal adapter (TA) with any of
three methods listed below:
• ISDN MTA128ST-USB Configuration Utility
This configuration utility is recommended for computers running Windows 2000/98/95
operating systems. Because it is a software-based utility, you can use it to create and
store as many configurations as you want.
• Windows 98/2000/XP Dial-Up Networking
Windows 98/2000/XP includes a remote-node client called Dial-Up Networking (DUN).
The MTA128ST-USB can be used with this client for data communications. Instructions
for configuring DUN are included in the on-line User Guide.
• AT Commands
If you prefer using AT commands or want to fine tune the operation of your unit, configure
your unit by using AT commands and S-registers much as you would configure an analog
modem. Enter these commands in your data communication program's terminal mode.
AT commands are described in detail in your on-line User Guide.
Whatever method you use to configure your MTA128ST-USB, before beginning the configuration
process, complete the following Network Configuration planning sheets and refer to it during the
configuration process.

Network Configuration

Network Switch Type

Select the network switch type your ISDN service provider uses at its local central office.
You can set the MTA128ST-USB to NET3 (DSS1), VN4, INS64, U.S. NI-1, AT&T 5ESS,
or DMS-100. If you don't know the switch type, get the information from your ISDN
service provider. AT command: !C0=
Data TEI
Data TEI (Terminal Endpoint Identifier) is the TEI assigned to the data channel. You can
select Auto TEI, a fixed TEI, or Disable. A TEI is a number used by the central office
switch to uniquely identify each device connected to the network. When it uses dynamic
TEI assignments (Auto TEI), the central office switch assigns a TEI each time the unit
connects to the network. However, the ISDN service provider may assign a fixed TEI at
subscription time, in which case you must configure the unit with the fixed TEI number.
You can also disable the channel, which may be useful when multiple units are attached
to a network terminator bus. AT command: !D3=
