Q1 : How to setup IEA128 on Windows 95 / NT?
A : In Windows 95.

1. Because IEA128 is a PnP device for Windows 95, please attach to PC’ s Com

port (serial port) and make sure this port is free in the system.

2. Windows 95 will automatically detect an ISDN TA device attached to PC,

please insert our installation disk or specify the subdirectory where the
MDMASUTA.INF is located. An async-to-sync PPP modem (for Internet
Access) will be installed automatically.

In Windows 95 and NT 4.0.

If you want to install more modems such as X.75, V.120, and MLPPP (128K), you
may follow this way to install it.

3. To add proprietary modems by Start à Settings à Control Panel à Modems

à Add à Select “do not detect my modem, I will select it from a list”, Next à

Select “Standard Modem Types”, Have Disk à Input the directory which has
the mdmasuta.inf, OK à Select a proprietary modem you want to install à
link this modem to the serial port. These modems will automatically issue
the protocol command to IEA128 when you select it to make a connection.

Q2 : How to setup IEA128 on Mac?
A : In Macintosh :

There are many applications which provide Internet Access, BBS access, or file
transfer. If you want to access Internet, you need a commercial Dial-Up
applications such as FreePPP, MacTCP, or Open Transport system to handle the
TCP/IP. The Mac OS 8.0 contains the Open Transport as default. If you use
FreePPP or MacTCP, you need to set the ATB4 for IEA128 to do the PPP
conversion (async to sync PPP conversion). You may set ATB41 or ATB42 for
128K MLPPP connection for better performance.

If you want to do BBS or file transfer, you need QuickLink II or Zterm terminal
applications. Please also set the B channel protocol for communication. The
AT commands for set B channel protocol are ATB0 (HDLC), ATB1n (V.110),
ATB2n (V.120), ATB3n (X.75) and ATB4n (PPP). Please refer User Manual for
more detailed information.

The following statements are for how to setup IEA128 for Internet Access on
Macintosh MacPPP.

"Echo Interval", "Terminal Windows", "Hang up on close", and "Quiet mode",
you can enable them according to your requirements.

8. For more configurations, you have to click the "Config...". Set the “Modem

Init" for default settings with Internet PPP (64K), AT&FB4.

9. From the "Config" window, finish every dialog box, like

"PPP Server Name" (e.g. My ISP),
"Port Speed" (e.g. 115200bps),
"Flow Control" (e.g. CTS&RTS(DTR)),
"Dial" (e.g. Tone dial),
"PPP num." (your ISP's telephone number, e.g. 81722043),
"Modem Init"(e.g. AT&FB4),
"Modem connection timeout"(e.g. 90 seconds),
"Authentication" (Auth. ID, Password, Retries:10, timeout:3 seconds),
"LCP" (if your ISP will not check the PAP, then disable the local and remote's

"Want&Will"),
"IPCP" (if your IP is assigned by your ISP, then leave all settings as default

settings).

10. Make sure every setting is correct and click "Done"

How to dial :

11. Now, you are ready to connect to your ISP by clicking "Open" in the "Config

PPP" window,

12. After clicking the "Open" button, the "MacPPP Status" window will be shown

on the screen and begin to dial. By the way, if you have enabled to bring up

Q3 : How to change the A-Law and u-Law without changing the ISDN

switch type?

A : Enter ATCODEC=0 for setting A-Law or ATCODEC=1 for setting u-Law. You

may also enter ATCODEC? to display the current setting.

Q4 : What is the ATS37 used for?
A : In some country, the Lower Layer Compatibility (LLC) is not shown in the Call

Setup packet and this field is used for compatibility checking such as V.110,
V.120 and so on. But others need this LLC to be sent for identification. The
ATS37 is used to control this. The default value of S37 is 0, not sending the LLC.
If this LLC is needed, please enter ATS37=128 to enable ISDN driver to send this
LLC out in Call Setup packet.

Q5 : How can I set the different ring pattern for POTS (analog port) 1 and

2?

A : You may use these AT commands to select the ring pattern for POTS ports.

ATS55=n for POTS 1 and ATS56=n for POTS 2.

Select the ring pattern for POTS 1, n=0 to 7

Pattern # Ring ON Ring Off
0 0.5 second 0.5 second
1 0.5 1.0
2 0.5 1.5
3 1.0 1.0

4 1.0 2.0 (default)

5 1.0 3.0
6 2.0 2.0
7 2.0 3.0

Q6 : Why can I not get the 128K (MLPPP) Internet connection at the

beginning, MP’s LED does not light on?

A : We provide two solutions of 128K Internet connection. The first solution is to

make a 128K call at the beginning and then fix to this rate till end of connection.
You may select it by ATB41. If you can not get the second B channel, the MP’ s
LED will not be lighted (ON).

The second solution is to make a 64K call first and then will make another call to

add 64K more till the data traffic is higher than the value of register 53. The
MP’ s LED will be lighted when data traffic higher than the value of register 53.
The default value is 4 (4* 1000 bytes). To know the value of register 53, enter
ATS53? This mode can be selected by ATB42.

From other viewpoint, the second B-channel connection will be disconnected if
average data flow below the value of register 53 and keep a while (default value

Last Release Date: 1998 , June 12

3

is 5 minutes, saved at register 54). To know the value of register 54, enter
ATS54?

We also provide the bandwidth dropping function for the voice call in this solution.
If there is an incoming or outgoing voice call, the driver will drop one B channel
first and allow the voice call to be received or transmitted. This B channel will be
added for data transmission till no voice call and data traffic is higher than the
value of register 53. This function is called Bandwidth on Demand (BOD).

If you do not want to be interrupted during data transmission by this method,
please select the above method (ATB41). Be noticed, we provide this algorithm
for bandwidth on demand after Version 1.09 or later.

Q7 : How can I set the MSN with a specified protocol such as X.75 or

V.120?

A : The MSN number is used to screen the incoming call. If you want to add a

protocol related with this MSN, you can use AT&ZIr=n*m*p. “n” for MSN, “m” for
subaddress (option), and “p” for protocol (option). For example, if you want this
ISDN line (81722043) to indicate an incoming call with X.75 Transparent protocol,
please enter AT&ZI2=81722043**3 to enable this function. Please refer the
Chapter 4 for more detailed information of AT command set.

Q8 : How can I set 230.4Kbps baud rate and save it into profile in TA?
A : We provide this function from firmware version 1.21.3 or later. When you use

115.2K or less speed to set 230.4K (AT%S1), this new baud rate is saved and
expect to receive the data from PC at this speed. If it can not receive correct AT
command from PC, the IEA128 will change to auto-baud rate detection mode and
try to catch the COM port speed.

Q9 : How to set the init string for some IP sharing devices or devices with

COM interface?

A : If this kind of devices can not receive correct returned string from IEA128, we

suggest to add this AT command into init string, AT&AB1. For example, the
original init string is AT&FB4, we suggest the init string to be AT&F&AB1B4.
With this AT command, TA will fix the baud rate and use it to catch data from DTE
(PC) site.

Q10 : How can I do the IEA128 self test?
A : If you are using the terminal program, you may enter AT&TEST to inform the TA

to do a self test. But if you do not have PC connecting to TA, you may use a
telephone set which provides the TONE dialing. Please connect this device to
POTS1 or POTS2. The self test procedures are as follows.

Procedure : Off-Hook and press Flash*0#

1. Off-hook ;

2. Enter FLASH, you will see the T1 or T2 LED will flash in 0.2 sec. ON and 0.2

sec. OFF ;

3. Enter *0# (three digits) ;

If the system is working fine, the T1 and T2 LEDs will flash in 0.5 ON and 0.5 OFF

and you will also hear the dial tone. If the system is BAD, the T1 and T2 LEDs
will flash in 0.1 ON and 0.1 OFF and you will also hear the busy tone.

Q11 :Why do I lose the TA configuration parameters every time if I upgrade

to a new firmware.

A : In the previous version (V1.21.3 and previous versions), it will erase the

EEPROM containing the system parameters if upgrade to a new version. From
the Version 1.21.4, the system parameters will not be erased if there is a
specified flag in the EEPROM. This means the system parameters
(configuration) will not be deleted after Version 1.21.4 if upgrade to a new
version.

Q12 :Why can I not get any response from IEA128 if I get an error in

upgrade procedure?

A : When you get an error in upgrade procedure, the TA is in upgrade mode now.

You will see the AA LED flashing. At this time, you can use a terminal program
and configure the COM port as 115200, N, 8, 1 to get the response from TA.
When the TA be powered on and find itself is in UPGRADE mode, TA will set the
UART (com port) to 115200, N, 8, 1 as default. The COM port of terminal
program should be configured the same value to continue the upgrade job.

Q13 :Why do the connection be terminated after approximate 4 minutes

with ZyXEL ISDN router, even there is traffic in the B channel?

A : Please take a look at the parameter settings on the routers, and found a setting

named, Recv Authen, which is a password/security option. If it is NONE, please
set it to PAP. Then this case will not happen again.

Q14 :Why is the ISDN monitor in sleep mode (no message displayed in the

monitor window), even the IEA128 is in active mode?

A : The ISDN monitor is based on CAPI interface to communicate with IEA128, but it

will not setup a link with IEA128 automatically. Therefore if there is no CAPI
application alive, the ISDN monitor is not alive too. This ISDN monitor may just
find the IEA128 and goes into sleep mode. If there is a CAPI application alive,
the D, B1, B2, and CAPI messages will be shown in the ISDN monitor. If the
application leaves, the ISDN monitor goes into sleep mode again (release the
physical COM port to other applications).

Q15: Can I use IEA128 to send G3Fax or other voice services?

Last Release Date: 1998 , June 12

A: Yes, you can. RVS-COM Lite. With this software, you have Software G3FAX,

voice mail, and others. But if the RVS-COM Lite version is less than 1.36, you
need to install our CAPI driver for IEA128 first, then install the RVS-COM Lite,
and check the “installing CAPI adapter”. Then these voice applications will work
fine.

If the RVS-COM Lite is version 1.36 or later, you can check “installing ISDN
terminal adapter” to install RVS-COM Lite and do not need to install CAPI driver
for IEA128. Then you may select the “ISDN TA” from the modem selection list
as our modem model and follow the instructions to install RVS-COM Lite. For
RVS-COM Lite information, you may access http://www.rvscom.com for more
detailed information.
