Getting Started

This Quick Start will help you install and configure your
Terminal Adapter (TA). Before you begin, verify you switch
type and TEI with your local ISDN provider and record that
information in Before You Start in Chapter 3 of the User
Guide.

Before You Start

Safety Warnings

• Never install telephone wiring during a lightning storm.

• Never install a telephone jack in a wet location unless

the jack is specifically designed for wet locations.

• Never touch uninsulated tele phone wires or
terminals unless the telephone line has been
disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

• Avoid using a telephone (other than a cordless type)

duri ng an electrical storm. There may be a remote risk of
electrical shock from lightning.

• Do not use the telephone to report a gas leak in the
vicinity of the leak.

• Ports that connect to other apparatus are defined as
SELV. To ensure conformity with EN 41003, ensure
that these ports connect only to the same type of port on
t h e ot h e r apparatus.

Network Configuration

The following describes network configuration. Other types of
configuration are included in the User G uide.

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 ty pe, get the informati on from your ISDN
service provider.

AT command: !C0=

Data TEI

Data TEI is the TEI assigned t o 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 assignme nts (Auto TEI), the cent ral office
switch assigns a TEI each time the TA conne cts 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 TA s 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=.

Data MSN

The Data MSN (multiple subscriber number) allows a caller to
specify an individual TA when more than one TA is connected to
you network terminator. If you don’t assign a value to the MSN,
the TA accepts all incoming calls. If you only assign a base
address to the MSN, the TA accepts any incoming call with the
same base address, regardless of whether a subaddress is
included. If you assign a base address and a

subaddress to the

MSN, the TA only accepts calls that match both the base
address and the subaddress. The following examples show the
syntax for setting the MSN with and without a subaddress.

AT command: !N1=

MSN with subaddress: 5551000:001 (base address is

5551000; subaddress is 001)

MSN without subaddress: (base address is 5551000)

Voice MSN

Selects calls on the voi ce channel in the same way the Data
MSN selects calls on the data cha nnel.

AT command: *!N1=

SPIDs and DNs

The TA must be configured with the Service Profile Identifier
(SPID). The SPID is assigned by the local phone company and is
for the specific BRI line where the TA is attached. The SPID field
is empty prior to configuration.

AT commands: AT!C6= and AT*!C6=

Directory Number (DN) is the phone number another user calls
to contact this TA once it is attached to the ISDN.

AT commands: AT!N1= and AT*!N1=
Note:

SPIDs and DNs are used only by the U.S. NI-1, AT&T

5ESS, and DMS-100 switch types.

Connecting Your TA

Turn off your computer. Place the modem in a convenient
location, connect it to your computer’s serial port, to the phone
line, to AC power, and to your phone.

Connect the TA to the AC Power Outlet

Plug the DC power transfo rmer in to an AC pow er outle t or pow er
strip. Plug the DC power transformer into the POW ER jack on
the TA.

Note: Use only the DC power transformer supplied with the TA.
Use of any ot her transf ormer voids the warra nty and can
damage the TA.

Turn on the TA by sliding the power switch to ON and verify
operation by observing the LEDs on the front panel. The LEDs
first flash in a self-test pattern. Then the LS LED remains on. If
the TA does not appear to be working, Refer to Chapter 5 for
troubleshooting help.

Connect the TA to Your PC (RS-232 Connection)

Plug one end of the RS-2 32 serial cable into the RS -232
connector on the modem, and plug the other end into a serial
port connector on your computer, such as COM1 or COM2. You
supply the RS-232 cable.

Connecting to your ISDN Network Terminator

If you need a longer cable than the one provi ded with your TA,
select a cable that is wired straight through (pin 1 to pin 1; pin 2
to pin 2, etc) with at least the middle four pins connected (pins 3,
4, 5, and 6).
Plug one end of the cable into the ISDN jack on the TA and the
other end into the jack on your network terminator (MTA128ST)
or U-interface (MTA128NT).

Note: The PHONE jack and ISDN jack are not interchangeable.

(Optional) Connecting to Analog Equipment

You can connect an analog device such as an analog
telephone, modem or fax machine to the TA. Simply put the
device’s module telephone cable into the PHONE Jack (RJ11)
on the TA.

Note: The PHONE jack and the IDSN jack o n the TA are not
interchangeable.

Configuring your TA

If you use Windows 98/ME/NT, perform the following procedure
using the Configuration Utility provided on your system CD. If
you are using another operating sy stem, you can configure the
TA using the firmware-based configuration utility or AT
commands. Procedures for both are described in the User
Guide.

Before you begin, verify your switch type and TEI with your local
ISDN provider and have that information readily available

1. When installing from CD, insert the MTA1 28ST/NT System
CD into your CD ROM drive. When the MTA128ST/NT
Terminal Adapter AutoRun screen is displayed, click on the
Config Utility icon. Follow the on screen directions to load
the Configuration Utility onto your PC.

2. When the Configuration Utility is loaded onto your pc, click
Start>Programs>ISDNTA Config Utility. The Welcom e
