Configuring the Terminal Adapter

3.9.1 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 Utility. Recommended for computers with Windows 98/Me, Windows NT, and
Windows 2000.
•
AT Commands. Use AT commands and S-registers to fine tune TA operation. You enter these
commands in your data communication program's terminal mode. AT commands and S-registers are
described in detail in a separate chapter of this manual.

3.9.2 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
The Directory Number (DN) is the phone number another user would call to contact this TA once it is
attached to the ISDN. AT commands: AT!N1= and AT*!N1=
Note: SPIDs only apply for North American switch types.

3.9.3 International Users

The terminal adapters ship already configured for NET3, which should work for most telephone lines in
Europe. If you want to customize settings, refer to the "Optional Settings" section of this chapter.
