1. Introduction

The ISDN TA (Integrated Service Digital Network Terminal Adapter) is a communication product
for the Internet and digital communication era. It provides high speed and high quality
transmission. The TA supports two analogs and one digital port. The two analog ports act like two
regular telephone lines, which can be connected to regular telephone, answering machine, fax and
modem products. Also, the TA can provide flexible functions like: supplementary service, call
screening, speed dial and global call function to meet user’s requirements. The digital port with
the RS232 link can be connected to PC to support data communication with remote site. It
supports many protocol selection such as V.110, V.120, X.75, X.25 on D channel, PPP (Point-to­Point Protocol), MLPPP (Multi-Link PPP), BACP (Bandwidth Allocation Control Protocol) /
BOD (Bandwidth On Demand) function. With the MLPPP, the entire 128k ISDN bandwidth can
be used to access the Internet. The BOD function can utilize dynamic bandwidth demand under
MLPPP connection. Under MLPPP data connection, the TA will automatically release one B
channel for voice communication when the user picks up the phone to make a call and returns to
two B channels for MLPPP when the phone hangs up. With the BACP function, the 128k capacity
of ISDN can be utilized fully. The TA is equipped with channel bundling feature which allows the
user to use both B channels to maximize the 128k bandwidth for data transmission.

The TA complies with ITU-T Q.921, Q.931 for D channel protocol, and provides switching type
selections for different countries. Following are the switch types supported by the TA:

*Euro-ISDN EDSS1

The TA is equipped with flash EPROM for easy future software upgrade through RS232 port.

5.2 What Else You Need

In order to complete your data communication system, you will need the following items:

1. Some type of communication software, if not included (like dialup network).

2. An ISDN U-interface line from the local PTT NT1. This TA gets connected to the ST

interface of the NT1 (which is supplied by your PTT).

5.3 Installing The TA

The following instruction explained how to install the TA with a PC or PC compatible

computer. If you install the TA into a different computer, refer to the manual that came with

or contact your dealer for instructions and assistance.

IMPORTANT:

In PC environment, two serial devices configured to use the same COM port or IRQ

may conflict. Existing multi-I/O cards usually occupies COM1 and COM2 using IRQ4

and IRQ3 respectively. Whereas the COM port setting must be unique, the IRQ can be

shared provided that the related COM port is not being used. For example, if the PC’s

COM2 which uses IRQ3 is not attached to any device (print or mouse, etc.), then your

TA can be set to use COM4 with IRQ3. For maximum flexibility, your PC supports

IRQ2, 3, 4, 5, and 7. However, IRQ2, 5 and 7 should be used only if you have no other

choice. Not all PCs and DOS versions support these IRQs. IBM PC/AT computers and

compatibles should be able to use IRQ5 or 7. Check with your PC dealer or PC manual

for more information.

Turn off the power on the personal computer.

Refer to section 4 to select the adequate method for connection.

5.5.4 Tips on configuring your Dial-Up Network

After you setup the ISDN TA driver completely. The next step is going to have your Dial-Up

network working. Following tips will guide you how to configure your Dial-Up Network

with Windows 98SE/Me/2000

1) Ensure that you have

1.

installed Dialup server and
Dial-Up Networking in
your windows
environment (Win 98SE).

2) In Win NT ensure that
RAS (Remote Access
Server) is installed.

3) Choose Dial-Up
Network icon from ‘My
Computer’ window.

Click the ‘Make New

Connection’ icon

twice to create a connection

.

Note! If you use ML PPP 128K driver then TCP/IP header compression has to be off

And DNS -values has to be set up correctly in TCP/IP properties.

5.6 Verifying Your Connection

Start a communication program (HyperTerminal) and place the computer in terminal mode.

Refer to your computer manual to find out the appropriate commands to do so.

Follow these procedures to verify your installation:

1. Type

AT [Enter]

If your system is operating properly, the TA will respond with ‘OK’ message to your

screen and will wait for the next command.

Use your communication software to prepare your computer to dial a data call.

2.

For example, you can test the data connection under V.110 protocol with the following

procedures.

AT%A2 = 1 ; Select V.110 communication protocol.

ATD 5552121 ; Where 5552121 is the called party’s telephone number with V.110

protocol setting.

After ATD5552121 you can see the TX/RX LED is lighted and then, the ‘CONNECT’ or

‘NO CARRIER’ message will be displayed.

CONNECT

; Means TA connected with the Called Party.

NO CARRIER; Means TA did not connect with the Called Party, may be due to

Called Party busy.

6. AT COMMAND

6.1 Description of AT Command

Hayes command set is a standard for Hayes modem commands for its Smart modem 300. Most

modem manufactures adopted this command set in order to have Hayes compatible. The command

set used by the Smart modem 300, as well as most modems or TAs today (with a few additional

new advanced commands), is known as the AT command set. AT stands for attention, and is

placed in front of actual content of command so that the TA knows what follows is an command

directed at the modem or TA. With the exception of some “A/” and “+++” command, “AT”

command is the process to place command to the TA.

Different modems or TA’s may have slightly different command sets, but generally speaking, most

of the TAs follow the standard set by Hayes.

6.1.1 AT Command

When you connect terminal equipment (like PC) with the TA, after typing AT command ending

with [ENTER] key, TA will process the command and then return the result code to the terminal

equipment. Each AT command must starts with “AT” and end with [ENTER] key (with the

exception of “A/” and “+++” commands).

Command Format

The following is the format of AT command:

AT

Command Value Command Value CR LF

Result code has two styles (Verbose and Numeric). The following are their formats:

CR LF Result

CR LF

code(Verbose)

Result code (Numeric) CR

S register

The S register is used to store the settings including

auto answer mode

escape sequence character

V.110 connect speed ..... etc.

If you want to change the value of S register, you can use the ATS command.

8. Re-Flash the New Software

8.1 Normal Re-Flash Procedure

To provide the upgraded software function in the future. The TA had been installed with the flash

EPROM for re-flash the new software function. Usually you should get the zipped (.ROM) file

from your local dealer directly or from your local agent’s Web Home Page. After you get the

.ROM file please follow the following procedure carefully.

(1) Use any terminal program that support ASCII file transfer function, like HyperTerminal.

(2) Enter into the terminal mode and make sure that the terminal program had set the following

configuration.

. 115200-baud rate

. 8 data bit, no parity, 1 stop bit (8N1)

. CTS/RTS hardware flow control

(3) Type AT and check TA responded with “OK”

(4) Type AT%FAPPS the screen will display the following message.

AT%FAPPS Application Upgrade

FLASH PROGRAM VERSION 1.4

Erase and reprogramming flash EPROM contents (y/n)?

(5) If you enter “n” then screen displayed

“Reset modem to continue”.

You need to power off and power on AFTER flashing TA to restart.

If you type “y” the screen will display:

*** WARNING ***

Erasing Flash Memory

Flash EPROM Upgrade Procedure

Ready for ASCII download

CTS (hardware) flow control

38400,8,N,1

>

(6) After you see the “>” character is appeared, you should select the new upgraded

39

software from the correct path. Select Transfer ->> Send Text File. Here give path of the .rom

file (*.ROM). Then click OK to start download. The screen will show the “>>>>>>>>>>” and

“<<<<<<<<<<” alternatively to indicate TA is downloading now.

(7) After finished the download new software, screen will display

“Code update successful”

“OK”

Normally it takes about 10 minutes to finish re-flash.

(8) After you see the message it means the download is completely already. You

need to power off and power on TA again to restart.

Type ATI3 to inspect the new software version.

(9)

8.2 Failed Re-Flash Procedure

Sometimes during the re-flash procedure, due to some accidents like: local power is off; PC is shut

down, RS232 cable is disconnected and etc. To prevent any kind of failed re-flash operation, TA

provides a so-called Minimum Operating Mode. When you failed to re-flash the new software,

TA will detect the failed re-flash internally.

D-LINK ISDN TA DMI-128ESU+

40

You must follow the procedures as below step-by-step.

(1) Power off TA.

(2) Check the RS232 cable is connected with PC well.

(3) Change the Terminal program to 38400 baud, 8N1, CTS/RTS hardware flow control.

(4) Entering the terminal mode again.

(5) Power on TA again, you will see the screen display:

“ Erase and reprogramming flash EPROM contents (y/n) ?

(6) Enter “y” and follow the steps from 8.1 (6) as stated above. Then you can still

finish the re-flash procedure. And you will see “38400, 8, N, 1” instead of

“115200, 8, N, 1”. Due to the baud rate is slower therefore it takes about 10

minutes to finish re-flash.
