Welcome to the world of ISDN communications.

You have acquired one of the finest ISDN terminal adapters (TAs) available today, model MTA128ST/NT

from Multi-Tech Systems. The MTA128ST is a desktop TA with an S/T interface port to connect it to the

ISDN network and an analog port to connect it to a telephone, modem, or fax machine. The MTA128NT is

a desktop TA with a U-interface to connect it to the ISDN network and an analog port to connect it to a

telephone, modem, or fax machine.The TAs ship with a software configuration utility for Windows® 98/NT/

ME, and ConfigMenu, a built-in configuration utility for Windows and non-Windows operating systems. In

addition, the MTA128ST/NT accepts AT commands that enable it to use the same communications

software as an analog modem.

The MTA128ST is compatible with the popular EuroISDN switch protocol, it communicates using ISDN BRI

(2B+D) service, which provides up to 128 Kbps data and voice communications, and it automatically

detects whether an incoming call is voice or data and handles it appropriately.

The MTA128ST/NT provides dial-up asynchronous communication capability with other personal

computers, terminals, on-line computer services, or other computer systems. Connection to your

computer/terminal device is made via the RS232 connector (ISDN). Connection to analog devices is

accomplished with an RJ11 connector and one RJ45 connector is used for your ISDN connection.

This User Guide will help you install, configure, and operate your MTA128ST/NT.

Product Description

There are two ISDN interface options,

S/T

and

. If you purchased the S/T interface adapter

(MTA128ST), you need an ISDN NT1 device connection to the ISDN switch. If you purchased the U

interface adapter (MTA128NT), it can directly connect to the ISDN switch (figure 1-1).

Figure 1-1. ”S/T” and “U” Interface Options

Your ISDN TA is compatible with prevalent ISDN switch protocols. It communicates using ISDN BRI

(2B+D) service, which provides up to 128K bps data communications.

Introduction and Description

MTA128ST/NT 5

This manual documents the following models:

• MTA128ST for S/T interface with one POTS port

• MTA128NT for U interface with one POTS port

Some analog devices, including telephone set, answering machine, and modem, can be connected to the

POTS port via an RJ-11 jack.

This User Guide will help you install, configure, and operate your terminal adapter.

Features

The MTA128ST/NT communicates over public ISDN telephone lines. Features include:

• Compatibility with EuroISDN (ETSI/DSS1/NET3), French VN4, and Japanese INS64 switch protocols

• Compatibility with U.S. NI-1, AT&T 5ESS, and DMS-100 switch protocols

• Compatibility with V.110 (some models only), V.120, ML-PPP, and X.75 protocols

• Transparent synchronous communication capability (CLEAR)

• ISDN BRI (2B+D) and analog ports

• RS232E serial port

• Serial port speeds to 460.8 Kbps

• Support of PPP (Point-to-Point Protocol) for high speed ISDN connections

• Tone detection to allow use of a standard telephone for ISDN line access (an ISDN telephone is not

required)

• Automatic detection of incoming calls as voice or data

• Windows 98/NT/ME software utility and a firmware utility for easy ISDN line configuration

• AT commands, S-registers, and result codes

• Ability to use the same communications software as analog modems

• Flash memory for easy firmware upgrades

ISDN BRI Line

Before running the ISDN adapter, you need to get an ISDN BRI (Basic Rate Interface) line from your local

telephone company. Your ISDN service provider will provide information to you about the ISDN central

switch type, pertinent subscriber information and SPID (Service Profile ID) number(s) if required .

SPID (Service Profile ID)

The Service Profile ID (SPID) is applicable in the U.S. only. SPIDs are a series of numbers that inform the

central office switch which services and features to provide to an ISDN device. The generic SPID format

comprises 14 digits. The first 10 digits are the main telephone number on the terminal. The last 4 digits

are dependent on the number of terminals on the interface and the services they support.

NT1 Connection

An ISDN Basic Rate (BRI) U-Loop consists of 2 conductors from the CO (telephone company central

office) to the customer premises. The equipment on both sides of the U-loop has been designed to deal

with the long length of the U-loop and the noisy environment it operates in. At the customer premises the

U-loop is terminated by an NT1 (network termination 1) device. An NT1 is a device which provides an

interface between the two-wire twisted-pairs used by telephone companies in their ISDN BRI network and

an end-user's four wire terminal equipment. The NT1 drives an S/T-bus which is usually made up of 4

wires, but in some cases may be 6 or 8 wires.

The name of the S/T bus comes from the letters used in the ISDN specifications to refer to two reference

points,

and

. Point

refers to the connection between the NT1 device and customer supplied

equipment. Terminals can connect directly to NT1 at point

, or there may be a PBX (private branch

exchange, i.e. a customer-owned telephone exchange). When a PBX is present, point

refers to the

connection between the PBX and the terminal. Note that in ISDN terminology, "

terminal

" can mean any

sort of end-user ISDN devices, such as data terminals, telephones, FAX machines, etc. The diagram

which follows reflects interface points in a typical ISDN network.

Introduction and Description

MTA128ST/NT 6

If your ISDN product operates with a S/T outlet interface, you need an NT1 device to connect to the ISDN

switch. MTA128ST adapters need an NT1 device to connect to the ISDN switch, but the MTA128NT

adapter does not require NT1 device. In the UK, and in many European countries, NT1 device is supplied

by your telephone company.

S/T Interface

The S/T interface uses an 8-conductor modular cable terminated with an 8-pin RJ-45 plug. An 8-pin RJ-45

jack located on the terminal is used to connect the terminal to the DSL (Digital Subscriber Loops) using

this modular cable.

Table 2-1 shows the Pin Number, Terminal Pin Signal Name and SILC Pin Signal name for the S/T

interface.

The U interface uses a 2-conductor twisted pair cable terminated with an RJ-45 jack. An RJ-45 jack

located on the terminal is used to connect the terminal to the Digital Subscriber Loops using this twisted

pair cable.
