Chapter 1 Introduction
Congratulations! You have purchased the terminal adaptor with the finest, smartest,
high-speed features.
This Documentation is valid for the products:
ISDN-TA/MLP: External ISDN terminal adaptor with two analog interface.
The term of 'TA' below represents ISDN-TA/MLP for the indication of general features.
1.1 Product Description
TA is an ISDN terminal adaptor connecting a existing PC (or other device with. Serial
port) to the ISDN. It gives access to on-line services as the Internet, CompuServe and
T-Online and is also suitable for a remote LAN access. You can see it as a digital
replacement for an analog modem.
If you are connecting to the Internet you will be able to use all of the features offered
by your Internet access program. These features vary from program to program.
They may include browsing, uploading and downloading files, using electronic mail,
and accessing World Wide Web sites and chat rooms.
If you are telecommuting, you will use the office network just as you would if you were
at work. For example, if you normally log into the office network for file retrieval and
storage, you will use the same procedure from your home PC to open and save files.
If you use electronic mail over a local area network (LAN) at work, you will be able to
use the same electronic mail program at your home.
You can also use the TA to connect to a single remote PC that contains another TA
via ISDN line. This allows you to use peer-to-peer network programs for file sharing
between two PCs. It also means you can transfer files between two PCs via common
communication software.
To work with TA you need.
- a ISDN Basic Rate Interface (BRI) (replacing an analogue telephone line)
- a PC with online software for a modem terminal program
The serial port of the PC should be capable of a data rate of up to 230400 bps.
This might require an additional PC card for external model.
The TA includes the following features:
-Compatible with ISDN central office switches for DSS1
-Status display LED
-Operating parameters saved in nonvolatile memory
-ISDN AT command set
-Convent configuration command
-Multi-link PPP (128Kbps)/ PPP async-to-sync HDLC transparent for main
Internet service provider
-Two optional analog telephone interface enable you to connect an analog
terminal (e.g. telephone, fax, PBX, or modem) to an ISDN Basic Rate line
-ITU-T V.120 - for CompuServe or others Internet service provider
-ITU-T X.75/ T.70NL - for T-Online Videotext service
1.2 Internet Access
There are several ways to access the Internet via ISDN.
- by Multi-Link PPP asynchronous-to-synchronous HDLC transparent
- by PPP asynchronous-to-synchronous HDLC transparent
- by bit rate adapt ion V.120
It depends on the access facilities of your Internet service provider (ISP) or
Point-of-presence (POP) which one you may use.
1.3 CompuServe Access
CompuServe is accessed via ISDN by the protocol V.120 or X.75.
1.4 T-Online
T-Online (German Online Service) is accessed via ISDN by the protocol T.70NL/X.75.
1.5 Remote LAN Access
To access a LAN remotely via ISDN you have to choose the appropriate protocol that
is used by the ISDN router on the LAN.
1.6 License

On the rear panel of the TA are the power switch, the power jack, and RS-232D
connector and one modular jack, as shown in the schematic below.
Fig 2-2 The rear panel of the TA
The power switch
Toggling the power switch to ''ON'' turns the TA on, while toggling the switch to ''OFF''
turns the TA off. It is recommended that you always turn on your computer prior to
turning on the TA, and turn off your TA prior to turning off the computer.
The power jack & power adaptor
The power jack for the power adaptor which is included with your TA. This TA
MUST use an AC 12V power adaptor. Always use the one supplied with your TA.
Use of another power adaptor may cause safety problems
The RS-232D connector
The RS-232D connector can be connected to the serial port of the computer through a
RS-232D cable. Your computer or terminal must have an industrial standard RS-232D
serial port to use this TA. Please have an RS-232D port (available from your dealer)
installed if your computer does not have one.
The TA can be connected to the serial port of the computer via a serial cable. Be sure
to specify the appropriate type of connector (DB-25 or DB-9, male or female) for each
end of the cable. Your TA follows industry standards in wiring the pins of the cable
connectors, therefore, any cable that would connect a TA to your computer will work.
Refer to Appendix C RS-232D connection, or consult your dealer if you need the
pin assignment of the connector.
The modular ISDN jack
The one modular jack labeled " TO S/T ", located on the right side of the rear panel,
is for the connecting cables from the ISDN BRI line.
Be sure that the ISDN line condition is in good order before connecting the TA. Test it
by lifting for example an ISDN telephone handset and listening for a clear dial tone.
Note: We strongly recommend that you connect the TA directly to the central
office outside ISDN telephone line. Do not hook your TA to a business
ISDN system (PBX) unless the system is guaranteed to be good enough
for correct protocol handling data transmission and call control.
The analog telephone jack (A1 / A2)
The interface enables you to connect an analog terminal (e.g. telephone, fax, PBX,
or modem) to an ISDN Basic Rate line. Any convert tonal analog terminal
equipment which supports DTMF tone dialing can be plugged into the RJ-11 jack.
2.3 Installation Preparation
To install your TA the following items are required:
- A S0 interface (basic rate interface) with IAE plug (Western RJ).
- A PC with the appropriate Internet software installed.
2.4 Installing the TA
The distance between the computer and the TA will be determined by the length of
the RS-232D cable. A suitable location for your TA should be:
1) Near a reliable AC power source.
2) Close to a good quality ISDN telephone line.( According to I.430)
3) Where the LED indicators on the front panel are clearly visible.
4) Where the power switch could be easily reached.
5) Where you are able to monitor the TA's carrier signal.
To connect the hardware, Please follow the procedures below:
1) Make sure both the TA and the computer are turned off.
2) Connect the TA to the computer:
Use a RS-232D cable between the TA and the computer. Plug the male DB-25
connector of the RS-232D cable to the TA.
Then, plug the other end of the cable to your computer serial port. Fix all of
the screws on the connectors.
For the use of data rates up to 11.5K bps. The RS-232 cable should not be too
long.
Note: Write down the computer serial port number ( COM1, COM2, COM3,
COM4) to which you have connected the TA. This port number
should be identical to the number listed in the communication software
configuration.
3) Connect the TA to a ISDN telephone line:
Plug one end of the supplied ISDN telephone cable to the outlet.
Then, plug the other end to the jack marked "S / T" on the rear panel of the TA.
4) Connect the power supply to the TA:
Insert the plug of the power adaptor into the jack marked "POWER" on the
rear panel of the TA.
Please check if the factory settings fit with your environment. The factory setting is
described in the parameter list show in chapter "AT Command Set".
If you want to change the factory default setting, please do the following steps:
- Connect the TA to ISDN interface and connect the power supply to the mains
socket.
- Start a terminal emulation program on your PC.
- Setup the parameter of the TA from the terminal emulation and save the
parameter.
- Leave your terminal emulation and start your application program.
2.5 Communications Software Configuration (for all of models)
Most popular communications software packages will work well with your TA. You
may, however, prefer to purchase the recommended TelixTM communications
software package, which should be available from your dealer.
Turn on your computer first, then the TA. Boot the communications software and
check the following parameters:
1) The serial port number.
2) The communication speed and protocol.
3) Data format: data bit, stop bit, parity.
Set the serial port number to COM1, COM2, COM3 or COM4 according to which your
TA is connected. Note that one port should be assigned to only one device;
otherwise, the two devices will conflict with each other.
To use the TA to dial a remote TA or server, the protocol, speed and data format of
both side should be set to match each other. For example, if the remote side you are
going to dial supports V.120, 57600bps, 8 data bits, no parity, 1 stop bit; you should
set communication software to the same parameters.
Software configuration tips
If your computer is an IBM PC, XT, AT, 386, 486 or Pentium and you are using
ProcommTM, BitcommTM, CrosstalkTM or most other communications software
packages, the factory default settings of the TA should correct.
However, if you are using SmartcomTM, the software requires that the DTR (Data
Terminal Ready) always be forced true. You should insert the command &D0 into the
dialing prefix.
To use the terminal in manual operation, you should insert both commands &C0 and
&D0. For example, AT&C0&D0DT.
To configure your TA for auto-answering, set register S0 to a non-zero value. For
example, inserting S0=2 into the command string instructs the TA to auto-answer
incoming calls calls after the second ring.
To meet some special requirements, you may need to change some other parameters,
such as the duplex mode, the auto line feed, the emulate, and so on. Consult an
experienced modem or ISDN TA user or your dealer for the required adjustments.
Regrettably, we are unable to describe software configuration procedures in greater
detail, as the procedures vary from software package to software package, from
computer to computer, and depend on the application. Refer to your software manual
for more detailed information. If you have any difficulty, consult an experienced
modem or ISDN TA user or your dealer.
Getting Started
Now boot the communications software and instruct it to dial a server, or remote
computer with a TA. Your TA should proceed with the call and establish a
connection automatically. Then you can:
1) Read or send electronic mail.
2) View the most updated news or information.
3) Upload or download computer programs.
4) Transmit or receive a text message or spread sheet data.
5) Play interactive games with the remote user.
With your TA completely installed, discover the fun and convenience of data
communication.
Chapter 3 Using the TA
3.1 Configuration for Internet
To access the Internet via ISDN you have to have a contract with a Internet service
provider (ISP) who runs an ISDN access. To configure the TA you need the
following information of the ISP:
- ISDN telephone number
This phone number is used to enter the Internet every time you call.
- Layer 2 protocol
This protocol should be configured in the TA, via command or Window
setup procedure.
- Internet access protocol
These protocol stacks are provided by the Internet software. For example:
TCP/IP, PPP protocol.
To configure the Internet access software on the PC you need some additional
information like TCP/IP address, user name, password etc. Please refer to the
software manual.
3.2 Configuration for CompuServe
To access the CompuServe network via ISDN, you have to have a contract with
CompuServe. To configure the TA you need the following information from
CompuServe:
- ISDN telephone number
This phone number is used to enter the Internet every time you call.
- Layer 2 protocol: V.120 async
This protocol should be configured in the TA via typing "AT!Z=5".
You can use a CompuServe access by a running standard terminal emulation.
3.3 Configuration for end-to-end data transfer
To transfer data at end-to-end point via ISDN you have to a terminal program
access. For configuration you have to setup the following parameter:
- ISDN telephone number at both side
This phone number is used to enter the remote site every time you call.
- Layer 2 protocol
Give one kind of the initial string as follows at TA of both side:
1.AT!Z=5 <Enter> -use V.120
or 2.AT!Z=6 <Enter> -use V.110 (option)
When V.120 is used, DTE speed can be selected from300, 1200, 2400,
4800, 9600, 19200, 38400, 57600, 115200bps.
When V.110 is used, DTE speed can be selected from 115200, 57600,
38400, 19200, 14400, 9600, 7200, 4800, 2400, 1200bps.
- Select the appropriate file transfer protocol like Z-MODEM in your terminal
program after connection to send the file you want.
Chapter 4 AT Command Set
With the exception of the A/ command all of commands begin with the prefix AT
and are terminated with <Enter>. Corrections in a command line are done with
<Backspace>. A command line has a maximum of 40 characters, the command line
is automatically cancelled by longer input. Blanks are ignored, capital/small letters
are not significant.
The parameter settings of the TA obtained via using the AT commands are
permanently stored by typing AT&W and are not lost by reset or by leaving the AT
command mode.
To enter the AT command mode during an active data connection you must use
the following sequence: ("scope sequence")

Flash program updating procedure
TA includes code which allows the user to update firmware in the FLASH without
removing it from TA's board. How to upgrade the code, please do the following
commands:
For mate: FLASHTA -COM x FILENAME.BIN
select the serial port your TA used
Example: FLASHTA -COM2 TAMLPE.BIN
Note: 1.During programming, don't turn the PC or TA off.
2.Don't use the DOS environment escape from Windows
The DOS environment "MUST" start from reboot.
Configuration Utility program for Windows:
This program allows the user to configure the TA and update firmware under
Windows.
Step1: Into the "START\RUN" icon
Step2: Insert the driver diskettes to Floppy
Step3: Run A:\ configta.exe
FLASHTA.EXE command parameters
The FLASH download program, FLASHTA.EXE, is a DOS real-mode program.
Its purpose is to read the ROM image binary file and transmit the contents to the TA
via a serial COM port using a packet protocol. FLASHTA.EXE accepts the following
command line parameters:
Parameter Required? Description
-COMx YES COM port to which the TA is attached.(COMx should
be from COM1 to COM4)
-IOxxxx Optional Specifies the IO port address of the COM port. The
value 'xxxx' should be a 3 or 4 digit hexadecimal
number specifying the port address. The default
addresses are:
COM1=3F8,COM2=2F8,COM3=3E8,COM4=2E8.
-IRQxx Optional Specifies the IO port interrupt level. The value 'xx' is a
one or two digit decimal number from 1 to 15. The
defaults values are:
COM1=4,COM2=3,COM3=4,COM4=3.
-Bxxxxxx Optional Specifies the maximum baud rate to be used. This is the
maximum rate at which FLASHIMG.EXE will attempt
to transmit data to the Ta(a lower rate may be used if
the program determines that reliable transmission
cannot occur at the higher rates.)The default value is
115200.
-F Optional If this parameter is present, the automatic revision level
checking is disabled and the FLASH download is
performed without verifying that a 'down-level' load is
being attempted.
-R Optional If this parameter is present the TA is assumed to be in
FLASH download mode, most probably as a result of
a previously aborted FLASH download attempt; no AT
command sequence will be sent (the sequence required
to place the TA in FLASH download mode).
filename YES File name or complete path name, if necessary, of the
ROM image binary file to be FLASHed into the TA.
