Configuring the Terminal Adapter
Introduction
North American users must configure the terminal adapter to match
network switch type, the service profile identifier (SPID), and the
directory number (DN). For international users, the terminal adapter
ships already configured for NET3, which should work on most phone
lines in Europe. However, you may want to customize settings,
regardless of your location. (See Optional Settings below.)
You can configure the terminal adapters with the ISDN TA
Configuration utility, ConfigMenu, or with AT commands.
Instructions for all three are provided in this manual.
ISDN TA Configuration Utilityrecommended for computers with
Windows 95/98/Me, Windows NT, and Windows 2000.
ConfigMenurecommended for computers with DOS or Windows
3.x and a VT100/ANSI compatible terminal or data communication
program that includes VT100/ANSI terminal emulation.
AT Commands. You can use AT commands and S-registers to fine
tune TA operation. You enter these commands in your data
communication programs terminal mode. AT commands and S-
registers are described in detail in a separate chapter of this manual.
North American Users
Before you connect the ISIHI or ISIHP to your network terminator,
you must configure it to match the following:
Network Switch Type ____________________
Select the network switch type your ISDN service uses at its local
central office. You can set the TA to NET3, AT&T 5ESS, NT DMS-
100, or US National ISDN-1. If you don't know the switch type, get
the information from the local phone company. AT command: !CO=
SPIDs and DNs ________________________
The TA must be configured with the Service Profile Identifier
(SPID). The SPID, assigned by the local phone company, is for the
specific BRI line where TA is attached. The SPID field is empty prior
to configuration. AT command: AT!C6= and AT*!C6
