Multi-Tech Systems MTA128NT 用户手册

You can configure the MTA128ST/NT to match your ISDN service and the remote terminal adapter (TA)
with any of four methods listed below:

•

ISDN TA Configuration Utility
This configuration utility is recommended for computers running Windows 98/NT/ME operating systems.
Because it is a software-based utility, you can use it to create and store as many configurations as you
want.

•

ConfigMenu
This firmware-based configuration utility is recommended for computers running other OS with terminal
capabilities. To run it, you must have a VT100/ANSI-compatible terminal or a data communication
program that includes VT100/ANSI terminal emulation.

•

Windows Dial-Up Networking
With Dial-Up Networking you can gain access to shared information on another computer, even if your
computer is not on a network. The computer you are dialing in to must be set up as a network server for
you to use its shared resources. Windows includes a remote-node client called Dial-Up Networking
(DUN). The MTA128ST/NT can be configured to communicate using this utility.

•

AT Commands
If you prefer using AT commands or want to fine tune the operation of your TA, configure your TA by
using AT commands and S-registers much as you would configure an analog modem. You must enter
these commands in your data communication program’s terminal mode. For more information see ST
and NT AT command documents included on this CD.

Whatever method you use to configure your TA, consider your network and call control configuration
choices and COM port settings beforehand listed below and record your choices. Refer to them during the
configuration procedure.Before you begin, verify your switch type and TEI with your local ISDN provider
and have that information readily available

Network Switch Type __________________________
Select the network switch type your ISDN service provider uses at its local central office. You can set the
MTA128ST/NT 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 is the TEI assigned to the data channel. You can select Auto TEI, a fixed TEI, or Disable. A TEI
(terminal endpoint identifier) 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 TA connects to the network. However, the ISDN service provider may assign a
fixed TEI at subscription time, in which case you must configure the TA with the fixed TEI number. You also
can disable the channel, which may be useful when multiple TAs are attached to a network terminator bus.
AT command: !D3=

Voice TEI ____________________________________
Voice TEI is the TEI assigned to the voice channel. Choices are: Auto TEI, a fixed TEI number, or Disable.
AT command: *!D3=.
