customer

The proliferation of PCs and LANs with bandwidth intensive applications, has
generated a powerful demand for high-speed connections. The worldwide
standardization of ISDN, combined in many countries with its growing availability and
falling cost, make it a natural choice for enhancing data throughput.

ISDN T/A 128 adapters provide high-performance solutions for Internet access, file

transfer, remote access service (RAS), video conferencing, and running existing
modem applications through the ISDN network.

ISDN T/A 128 Adapters

There are two types of ISDN interface of ISDN T/A 128 adapter, ST and U interface. If
you purchased the ST interface adapter (eg. IA128-ST), you need an ISDN NT1 device
connect to the ISDN switch. If you purchased the U interface adapter (eg. IA128-U), it
can directly connect to the ISDN switch. (figure 1-1)

There are two types of PC buses of ISDN T/A 128 adapter, ISA and PCI. Each bus (ISA
or PCI) and each interface (ST or U) has two models option, “D” and “DV”. All of the
features between “D” and “ DV” models are the same, except “ DV” model provides an
extra standard a/b (POTS) port.

IA128-ST

IA128-U

Figure 1-1 ISDN T/A 128 adapters connection diagram

You can easily get the information from “IA128-U-DV” type are ISA bus, ISDN card, U

1

interface and a/b port connections. Of course, “IA128P-ST-D” means PCI bus, ISDN
card, and ST interface connection only. “IA128” implies Planet’ s ISDN PC internal
adapter.

All of the current analog devices, including telephone set, G3 fax, answering machine,
modem, and PBX trunk line can be connected to the a/b port (RJ-11 jack) in “DV” model.
The data transmission rate of the “DV” model can up to 64 Kbps while analog
communication on-line, or up to 128 Kbps through Multilink PPP connection.

The Features of ISDN T/A 128 Adapters

You can use the ISDN T/A 128 adapters for Internet access, file transfer, remote access
to the computer network, and running existing modem applications through the ISDN
network.

The valuable applications and specifications of ISDN T/A 128 adapters

u PnP with 16 bits address decoding. Supporting of Windows 3.1, 95 (OSR-2),

u Supporting the multi-processors of Windows NT platform.
u All of the ISDN T/A 128 passive cards with the same driver, no matter ISA or

PCI bus, or current version or new version. The latest ISDN T/A 128 drivers
from web-site download can backward compatible with ISDN T/A 128 passive
cards.

Why ISDN?

The ISDN (Integrated Services Digital Network) is the standard for carrying both data
and voice simultaneously. ISDN BRI (Basic Rate Interface) line provides two B­Channels for voice or data transmission, and each B-Channel can provide data
transmission of up to 64 Kbps. The ISDN network uses the same transmission lines as
the existing analog telephone network, but using a digital signal and higher bandwidth
between the central office (phone company) and the customer. Aside from four times
faster than a standard 28.8 Kbps modem, ISDN also provides an extremely reliable and
stable digital connection.

The ISDN network can set up a connection in about 3 seconds. This is much quicker
than the PSTN network. This feature alone can result in great time savings in the longer
term.

Why High Speed Analog Modems Can Not Compete With ISDN Digital Connections?

“The high speed modem can run at 28.8 Kbps and will move data at ISDN-type speeds
when you consider data compression”. This assumes a noise-free telephone line and
that the data is easily compressed. Unfortunately, many image files cannot be
compressed easily, and many telephone lines are far from ideal. ISDN always operates
at its rated speed. Of course, ISDN cards can also use data compression technology to
multiply its raw data transmission speed.

Telephone monopolies allowing, ISDN will inevitably replace the existing analog
telephone network. The conversion is being driven by applications such as
telecommuting, home-working, remote LAN access, video conferencing and access to
the Internet. Today, ISDN is available almost everywhere so all users can should be
able to get the benefits from ISDN now.

Chapter 2 Before Installation

Before installation ISDN T/A 128 adapter, you need to check the package contents,
apply an ISDN BRI line, get a NT1 device (for ISDN T/A 128 ST adapter only) from your
phone company or retailed stores, and apply an Internet access account (if Internet
access required).

After you prepared the above items, you can start your environment setup. If you
purchased the adapter is “DV” model, you can connect your analog device to the RJ­11 jack (in the UK an adapter is supplied).

Package Checklist

In your ISDN T/A 128 package, you will find the following contents.

u ISDN T/A 128 adapter 1 piece.
u Installation Disk of CD-ROM for Windows 3.1, 95, and NT.
u RJ-45 cable 6 feet for ISDN connection.
u RJ-11 cable for a/b port connection (DV model only).
u USB cable (USB model only)
u (Quick) Installation Guidefor ISDN T/A 128 adapter.
u RJ11-BTS adapter UK only phone adapter.

Suggested System Environment

u Hardware IBM PC (or compatible computer) with 16 MB or more of RAM,

486 CPU or later capable of running Microsoft Windows.

u Software Microsoft Windows environment (Linux is the optional O.S.).

ISDN BRI Line

Before running the ISDN T/A 128 adapter, you need to get an ISDN BRI (Basic Rate
Interface) line from your local telephone company. Sometimes, your ISP may, upon
your request, order an ISDN BRI line for you when you apply an ISDN Internet access
account.

You should get the subscriber information from your ISDN telephone company, who
may inform you about your ISDN central switch type and SPID (Service Profile Identifier)
number, when you are in the US country.

4

What is SPID?

SPID stands for Service Profile ID. The SPID is applicable to the US country only.
SPIDs are a series of numbers that informs 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

The ISDN U-loop is terminated by NT1 device at the customer premises. The
connection between the NT1 and Terminal Adapter (ta) is called point “T”. The NT1
drives a 4-conductor S/T-bus which may be expanded to 8 conductors to provide for
emergency power. If your ISDN product with a S/T outlet interface, you need an NT1
device connect to the ISDN switch. ISDN T/A 128 ST adapter needs an NT1 device to
connect to the ISDN switch, but ISDN T/A 128 U adapter does not require NT1 device.
In the UK, and in many European countries, an NT1 device is supplied by your
telephone company. Therefore the ST adapter are required for these countries.

Internet Access Account

If you want to use ISDN T/A 128 adapter to connect to the Internet, you must get an
Internet access account from an ISP (Internet Service Provider) around your location.
You must also confirm with your ISP that they support ISDN access (either single
channel 64K or 128K MLP).

Environment Setup

All ISDN T/A 128 adapters are truly Plug and Play (PnP) compatible. Even if the BIOS
or computer main board does not provide PnP feature, the ISDN T/A 128 device driver
still can automatically configure ISDN card with proper I/O addresses and IRQ number.

1. Terminator setup of ISDN T/A 128 ST adapters (IA128-ST, IA128P-ST,
UI-1280ST)

F Please jump to the next section (2.) if you are the user of U interface adapter,

IA128-U or IA128P-U.

ISDN S/T interface can support up to 8 ISDN terminals and through NT1 device
connecting to the ISDN network. One and only one ISDN S/T device should have
the terminator enabled. Normally the ISDN terminal which is farthest from NT1
should have the terminator enabled.

ISDN T/A 128 ST adapter provides two jumpers of JP1 and JP2 (or DIP switch in

5

USB T/A) for the terminators setup, the default setting of ST adapter with terminator
enabled (DIP switch in ON). If there are other ISDN devices connected to the NT1
with ISDN T/A 128 ST adapter, and you do not need the ISDN T/A 128 ST adapter
as terminator, then please remove the JP1 and JP2 (open circuit, DIP switch in
OFF).

2. Insert the ISDN T/A 128 adapter

a. Turn off your computer power and remove the lid.
b. Insert the ISDN T/A 128 adapter into a spare PC ISA (or PCI) slot and secure it.
c. Replace the lid.

If you have UI-1280ST (USB) device, you can connect to the USB port directly.

3. Analog device connection (DV model only)

“DV” model of ISDN T/A 128 adapter provides a POTS interface (a/b port) with
RJ-11 jack to connect with current analog devices. Users can connect analog
telephones, G3 fax, modem, or answering machine with the RJ-11 connector cable
into the RJ-11 jack of the ISDN T/A 128 adapter. In the UK an adapter is supplied to
convert from the UK type 103 plug to the US RJ-11 plug. The REN (Ringer
Equivalence Number) drive capability or parallel ring number is 3, so you can
connect up to 3 analog devices, assuming each device has a REN of 1.

4. ISDN connection

Connect the ST (IA128-ST, P-IN110-ST or UI-1280ST) adapter and NT1 with RJ-

45 cable connector, and insert the ISDN BRI line into the correct NT1 socket.

OR

Directly Insert the ISDN BRI line with the RJ-45 connector cable into the RJ-45 jack
on the U (IA128-U or IA128P-U) adapter. Please kindly be informed that even RJ­45 connector has 8 pins and RJ-11 has 4 or 6 pins, but you can still plug cable from
wall jack with RJ-11 connector into RJ-45 jack on the U adapter. The ISDN T/A 128
U adapter still works correctly.

Under Windows 3.x applications can use the ISDN T/A 128 device using either COM
port emulation, the standard WinISDN interface, or the CAPI 2.0 interface.

1. COM Port Emulation. The ISDN T/A 128 driver provides AT Command Set

interpreter to emulate modem’ s actions and transfer/receive data through the ISDN
network. For modem users need set up the application software to the appropriate
COM ports (COM3 or COM4) to communicate with ISDN T/A 128 adapter. AT
Console program (see figure 3-2) can redirect the AT commands and data through
COM3 or COM4 to the ISDN T/A 128 driver to process them.

If you want to setup Internet environment through COM port emulation then

TRUMPET is the popular Internet shareware and includes the TCP/IP and PPP

protocols with Winsock interface. Most Windows 3.1 Internet modem systems use
TRUMPET connect to the Internet and run Internet applications such as Netscape
Navigator. The TRUMPET user should modify the Network Configuration and Script
files to access the Internet through ISDN T/A 128 adapters. See the Appendix C, the
example of modification of TRUMPET setup.

u

When entering the windows 3.1 system, you must run the AT Console to enable

the COM port emulation capability.

u

Multilink PPP is not supported at the AT-Console. You may get Multilink PPP

connection through the applications which include TCP/IP & Multilink PPP
stack with WinISDN or CAPI interface.

2. WinISDN Interface. The ISDN T/A 128 driver can transmit/receive data with

applications through the standard WinISDN interface. The following TCP/IP stacks
support the WinISDN interface.

u

NetManage’ s Chameleon

u

FTP’ s Explore

u

Frontier’ s SuperHighway Access

Please refer to their respective documents to setup the dial-up environment for
WAN and LAN. We recommend NetManage’ s Internet Chameleon (version 4.5 or
later) for compatibility using both PPP and Multilink PPP.

3. CAPI Interface. Applications can also access the ISDN T/A 128 card for up to 128K

data transmission and receiving through the standard CAPI 2.0 (or later) interface.

Removing ISDN T/A 128 for Windows 3.1

If you want to remove ISDN T/A 128 driver from your Windows 3.1, please click the

unInstallSHIELD icon (see figure 3-2).

Installation for Windows 95 Environment

This section includes the installation of ISDN T/A 128 adapter and application environment
setup. The supported application interfaces including WinISDN, CAPI 2.0, NDISWAN
Miniport adapter, and virtual modem in Windows 95.

Please read the following Windows 95 installation steps and setup procedures of the
NDISWAN Miniport adapters and virtual modems.

Installing and Configuring the Drivers

1. After you have inserted the ISDN T/A 128 adapter, switch computer power on and allow

Win95 to startup. When the Windows 95 system starts it should auto-detect a new PnP
card and request you to install its driver. Please insert ISDN 128K driver diskette/CD
into appropriate disk drive, run the ISDN100.INF file from the installation

diskette/CD, then Windows 95 system will automatically process the necessary

installation steps.

2. Please refer figure 3-3 for ISDN Configuration dialog box. In Windows 95 system, you

can set up (or change) the ISDN configuration of Switch Type, values of MSN and SPID
through the following procedures. Start à Settings à Control panel à System à Device
Manager à ISDN Card à ISDN PC Adapter, Properties à Settings.

Fig. 3-3 ISDN T/A 128 Adapter configuration

This features of ISDN configuration in Windows 95 is similar with the installation in

Windows 3.1 environment as figure 3-1. The MSN (POTS) value is only relevant to the
DV model and determines which telephone number to associate with the POTS
interface e.g. if the number 341317 was entered, then a normal telephone attached to
the POTS interface would be only rung when incoming call with the number of 341317.

11

If you want your analog device always ringing when receiving an incoming call,
please keep this field blank. For the UK and most European countries select the

EURO ISDN switch type with A-law Codec. The PTP mode sets the ISDN line as
point to point mode, you may set TEI value also if phone company specifies the TEI
value to you. Otherwise, let it as default (blank). The X.25 on D enables driver to
provide X.25 on D channel service and specify the TEI value also. Please leave it as
default value (blank) if it is not available in your ISDN service list.

3. After configuring the switch type, Windows 95 will request to restart system. After

restart the Windows, if you choose the “DV” model then you can connect a standard
analog telephone set into RJ-11 jack and should be able to hear the dial tone from the
telephone handset.

4. If you already installed the ISDN Accelerator Pack 1.1 (MSISDN11.EXE) or Dial-Up

Networking 1.2 (MSDUM2.EXE) in the Windows, then directly jump to the
application environment setup section. You may check from the property of

connection icon in Dial-Up Networking folder, if you see the “set additional devices” in
the general subwindow or “MultiLink” tab, it means your Windows 95 system already
support NDISWAN interface, please jump to the application environment setup section.

To update the Dial-Up Networking to support 2B channel (MLP) connection and
NDISWAN Miniport interface you will need to install the Win95 MSISDN11.EXE
(version 1.1 or above) upgrade pack. You can get the file from our Windows 95
installation diskette and also accessible from Microsoft web site. Run the

MSISDN11.EXE or MSDUM2.EXE program and follow the installation instructions.

5. Please reboot your PC for effectively ISDN Accelerator Pack features.

Application Environment Setup

After you complete the ISDN T/A 128 driver installation, you can execute the applications
based on the WinISDN and CAPI interfaces. Of course, you need installation the software
before executing the applications, please see the example of Appendix C for RVS-COM (lite
version) software installation. In Windows 3.1, you need to run the AT Console to enable
the COM port emulation capability. Under Win95 the COM port emulation is automatically
loaded at startup.

You can choose the either way of NDISWAN and virtual modem to connect to the
Internet or remote LAN. If you want to execute the Internet related applications or

RAS, we suggest that you setup and use the NDISWAN Miniport adapter interface.

Using the NDISWAN Miniport driver is the Microsoft preferred connection method.

If you want to execute the current modem applications, eg. Microsoft’ s
HyperTerminal or PC Anywhere, you should setup and use the virtual modem
interface through our COM port emulation function (we named the virtual modem).

12

The MSN1 and MSN2 are used for filtering the incoming call in separated ISDN

port1 (ex. IINWan95-Line01) and ISDN port2 (ex. IINWan95-Line02). For example,
if you want ISDN port 1 to receive telephone number 12345 only, you can enter
12345 into MSN1. The subaddress works like an extension number that your local
ISDN switch must provide this feature also. Usually, leave these fields with blank.

The Calling Party 1 and Calling Party 2 are used to indicate the ISDN switch (PTT)

that this call is made from this telephone number and bills the communication cost
based on this telephone number. Be noticed that MSN1 and Calling Party 1 are
reserved by ISDN port1, the MSN2 and Calling Party 2 are reserved by ISDN port2.

Installation for Windows 98 Environment

There are two types of Windows 98 drivers (VxD and WDM) at the installation CD-ROM
diskette. Both of the installation programs can install the ISDN driver, virtual COM port,
and NDISWAN Miniport driver at that same time.

VxD

Windows 98 system includes the NDISWAN Miniport interface, so you do NOT need to
install the ISDN pack (MSISDN11.EXE), and just choose the “isdn98” file from the
“Win98/VxD” subdirectory of installation CD-ROM when Windows 98 detects an ISDN PnP
card and requests to install its driver. The installation program will automatically process the
necessary installation steps for you (including the NDISWAN Miniport driver installation). To
configure the driver and setup application are the same as in above installation for Windows
95 environment section.

WDM

This section describes the installation of ISDN T/A 128 Win98 WDM driver. This driver

can be used for ISDN Internal cards, USB T/A and T/A. The supported application

interfaces including WinISDN, CAPI 2.0, NDISWAN Miniport, and virtual modem in the
Windows 98. The ISDN T/A 128 WDM driver also supports the multi-ISDN T/A 128

adapters in one PC system.

Installing and Configuring the Drivers

1. After you insert the ISDN T/A 128 adapter, power the computer switch ON, the Win98

will start up. Then the Windows 98 will automatically detect a new PnP card and
request you to install its driver. Please click “Next”, check “ Search for the best driver
for your device” and “Next” . Then insert ISDN T/A 128 driver diskette/CD into the
appropriate disk drive, run the ISDNDV98.INF file from the installation diskette/CD

(under WDM sub-directory), then Windows 98 system will automatically process the

necessary installation steps. The ISDN T/A 128 adapter driver, CAPI20 driver, two
virtual COM ports, and NDISWAN Miniport driver will be installed. This ISDN driver will
start automatically without reboot. You can use CAPI20 and virtual COM ports directly.
But you need to go to ControlPanel -> System -> Devicemanager -> Re-flash, then
NDISWAN mini port driver will be activated. Or reboot to enable NDISWAN miniport
driver. Be noticed, the ISDN pack is included in the Windows 98 as default, so

you do not need to install the ISDN pack again.

Chapter 4 ComPort Emulator

The ISDN T/A 128 adapters support Microsoft Windows Comm. API interface. This
allows applications (especially popular analog modem’ s applications) to access ISDN
T/A 128 adapters as an emulation modem (this is an emulation does NOT really support
fax or modem features). Windows Comm. API also enables existing applications based
on the AT command set to access ISDN. This feature is called the Comport Emulator
and also allows also extra AT commands to enable ISDN features such as HDLC, X.75,
V.110, V.120, or Async to Sync PPP (see list below).

1. Windows 3.1 system. Windows Comm. API is enabled only after running the

atloader.exe program, (double click the AT Console icon, see figure 3-2). AT
console will not be activated automatically at startup unless you add it to the StartUp
group in Windows 3.1. Normally you should activate yourself.

2. In Windows 95 system. Windows Comm. API is enabled automatically.

F

Windows Comm. API can only provide AT-emulation if the application
requests its COM port services from Windows. It cannot support the
application if it tries to access the com port hardware directly or if your
software does not use the standard Windows comm. driver interface.

The following AT Commands are provided to allow control of the ISDN connections, line
protocols and call handling. You should change your application setup-strings using
these parameters to access ISDN T/A 128 adapter with the correct protocol and settings.

Chapter 5 Troubleshooting

ISDN T/A 128 adapters provide “LINETEST” and “ LOG” utilities to test ISDN line status,
and monitor/record ISDN handshaking procedures and transmit/receive data contents.

You can use “LINETEST” to loopback test between ISDN switch and subscriber site, and
get the ISDN line status. If ISDN line work okay, you can use “LOG” to get detailed
information during ISDN communication. If you have any problems about connections,
you can use these tools to do self-diagnostic. You can also email or send the

contents of “LOG” file to our local technical support or us.

ISDN T/A 128 LINETEST

You can run “linetest.exe” in Windows 3.1 and 95, or “ lt32.exe” in Windows NT to
enable our “LINETEST” utility. After executed this program and you will be asked to enter
your own ISDN telephone number. After you click the StaRT, ISDN T/A 128 will enable
the call setup for testing. LINETEST will test the line status of ISDN B and D channels
between the ISDN T/A 128 adapter and the ISDN switch network.

If any errors are reported during the loopback test then please see the following listing
for explanations of the messages. If you get an error of 3301 or 3302, that means your
ISDN line is not connected properly. Please check your ISDN line connections.

F

Before execute LINETEST, you must make sure ISDN line is available for
testing (i.e. no other person is using the ISDN line).

ISDN T/A 128 ISDN LOG

There are six functions in the ISDN “LOG” utility, StaRT/STOP, SAVE, CLEAR, PRINT,
OPTION, and CLOSE. Figure 5-1 below shows a typical log screen. The upper text box
of the LOG dialog box records the ISDN communication information contents and the
lower white screen area logs statistical details of D and B-Channels events.

In Windows 3.1, “ISDN Log” will be executed after clicking “ ISDN LOG” icon (figure
3-2). In Windows 95, “ISDN Log” will be executed after run the “ log32.exe” located in
\windows directory. In Windows NT, “ISDN Log” will be executed after you run the
“log32.exe” located in \winnt\system32 sub-directory.

Start/STOP:

Begin or end data logging.

SAVE:

Figure 5-1 ISDN T/A 128 “ISDN LOG”

44

Save the entire log history contents to a disk file. If there is any problem, customers
can use this function e-mail or fax the LOG file to our local technical support center
or us.

CLEAR:

Clears the Log contents. You may want to save the data before erasing it.

PRINT

Send the Log contents to the printer.

OPTION:

When you click the OPTION tab, you will see the Options dialog box as shown
below. Using this dialog you can select to log specific types of line information for
the ISDN D channel, B channels, and CAPI messages. If you do not enable the
Show statistic item, you will not see the bottom part of the LOG dialog box (see
figure 5-1). The information pertaining to the ISDN D channel is presented in a
manner similar to that presented on a protocol analyzer. The information for ISDN B
channel and CAPI is presented with Hex format.

CLOSE:

Terminate the “PLANET ISDN Log” function.

Error Messages

You may encounter the following runtime problems.

1. “Can not find CTL3D.DLL”. This reports that your Windows system does not

provides 3D graphics. The ISDN T/A 128 driver will continue to execute normally but
without the 3D control graphic feature. You may contact your PC or system dealer to
upgrade your Windows system to get this extra feature.

2. “Irq Selftest Fail”. This reports that ISDN T/A 128 VxD driver failed its IRQ self-test.

Check the IRQ values in system Resources. Select Start à Setting à Control
Panel à System à Device Manager à Multi-function adapters, ISDN PC
Adapter à Resource. The PC system may have a non-PnP device using the same

45

IRQ number as ISDN T/A 128 adapter. This error is common in systems which have
an ISA bus sound card installed in the PC (using IRQ5). In this case choose another
IRQ number (probably both hardware and software configurations) for this non-PnP
device and reboot the system.

If using Win95 then you can change the IRQ used by the ISDN card in the device
manager. Use Control Panel/System/Device Management/Multi-function
adapters/ISDN T/A 128 PC Adapter (Master Device)/Properties/Resources then
disable the “Use automatic settings” option. Then select the Interrupt Request/
Change Setting and select a non-clashing IRQ value to use. If IRQ 5 is not
available then a good choice could be IRQ 10 or 12 but which ever one you use
check that there are no clashes.

3. “Can not find ISDN card”. This message describes that ISDN T/A 128 VxD driver

does not find the ISDN T/A 128 adapter when Windows starts. The problem may be
associated with an I/O address or IRQ clash during PnP initialization. Please check
your system resources. You may need to reinstall the ISDN T/A 128 driver.

Appendix C Applications

This Appendix gives the introductions of ISDN T/A 128 with the popular applications.

TRUMPET Setup through COM Port Emulation

In Windows 95 system, the virtual COM port driver will automatically be enabled on
system startup through Microsoft’ s Windows Comm. API.

In Windows 3.1 system, run the AT Console application from the ISDN T/A 128 group to
enable the COM port emulation capability. Trumpet is the popular Internet dialup
software in Windows 3.1. TRUMPET Provides the TCP/IP stack including PPP and
COM port interface. You should change the following parameters to access ISDN T/A
128 driver in Windows 3.1.

F

Run “AT Console” first to enable COM port emulation.

1. Select Setup ... option from the File menu. Use COM3 or COM4 for SLIP port.

Sometimes the default for TCP MSS is 1460, this does not work and should be
changed to 1400.

2. Select Edit Scripts ... option from the Dialer menu and select to edit login.cmd.

You must to edit login.cmd to make a successful PPP connection through
ISDN. Refer to the following statements to edit your own login.cmd

#
if ![load $number]
if [query $number “Enter your dial up phone number”]
save $number
end
end
if ![load $username]
if [username “Enter your login username”]
save $username
end
end
if ![load $password]
if [password “Enter your login password”]
save $password
end
end
$modemsetup = “Z”
$prompt = “>”
$userprompt = “sername:”
$passprompt = “assword:”
$slipcmd = “slip”
$addrtarg = “Your address is”
$pppcmd = “ppp”

%attempts = 10
#---------------------------------------------------------­# initialize modem

3. This completes the basic setup for ISDN access. You will also need to modify

certain other parameters, such as dial number, login name, and password if
required. These parameters are application dependent and are not covered
any further here. If you use different the TRUMPET version, you may contact

our local distributor for support.

Microsoft HyperTerminal

If you are trying to use the HyperTerminal of point to point or BBS connection, you
should choose or add a virtual modem which is attached to the ISDN ComPort. Please
refer to Chapter 3 about Installation of ISDN T/A 128 driver and setup for virtual modem
in Windows 95 system. Ensure that you use the ISDN (X.75 Transparent, 64K) Adapter
modems or use the universal modems but use the ATB3n command in Advanced
Settings to select the X.75 protocol. (see below)

At the receiving site, you should enter ATS0=1 to automatically answer incoming calls.
Note that the default protocol in the B channel is HDLC 64K with packet size 2048. If you
would like to change the B channel protocol use the following steps.

Go to extra setting field : Start à Settings à Control panel à Modems à
Properties à Connection à Advanced à Extra settings. Please see Figure 3-

52

7 and Chapter 4 about ATBn setup.

We recommend you change the package size in B channel to improve reliability and
performance. Set packet size to 512 bytes using “ATS39 = 512” in Extra Setting field or
input the value manually. For example, to select a X.75 Transparent with 1024 packet
size for B channel connection use, ATB30S45=1024.

*

Note: the setting values for B channel protocol, packet size, or Window size
will be reset to default value when finish the application. If you would like to
make these changes permanent then enter the settings in the Extra settings
field as shown above.

Appendix D ISDN T/A 128 Virtual Modems

In this Appendix, it gives more explanations of the ISDN T/A 128 virtual modems and
their purposes. Through these virtual modems, it can benefit to our customers more

easy installation, and flexibly control your time and cost.

1. “Internet MLPPP”, the MLP (128K) access through our virtual modem of “ Internet

MLPPP”, customer does not need to install the MSISDN11.EXE or DUN1.2 for
adding the secondary device to achieve 128K Internet access.

2. “Internet MLPPP+BOD”, the MLP+BOD (128K) access through our virtual modem

of “Internet MLPPP+BOD”, customer dose not need to install the MSISDN11.EXE or
DUN1.2 for adding the secondary device to achieve 128K Internet access, and also
benefits the Bandwidth-on-Demand capability.

It means bandwidth (64K or 128K) will be depend on the data traffic and
incoming/outgoing voice call. At the beginning stage, it will establish 1B (64K) data
channel and wait the data traffic over the specific value (refer ATS53). If over this
value, it will establish another B channel and bundle it to be 128K communication
link for better performance. Once it is in the 128K mode and will drops 1 B channel
(64K) based on the following three conditions.

a. The average data traffic is lower than the value (ATS53) in a specific time period

(ATS54).

b. The customer wants to make an outgoing voice call such as picking up the

handset.

c. There is an incoming voice call, the analog telephone device will have a ring

signal.

With this BOD function, customer will have more flexibility to handle voice and
data simultaneously.

3. We also provide the virtual modems of PPP, MLPPP, and MLPPP+BOD over X.75

capability. If your ISP or RAS server provide these kind of function, please select

the virtual modem from our modem script file. Then it is more easy to configure and
make a connection with ISP or RAS server.

We provide the ATS30=n command for application to tell driver to disconnect the active
connection automatically if there is no data traffic for n x 10 seconds

55

How to configure the ISDN driver for above function ?

Please refer Chapter 3 section of “Adding virtual modems connecting with two ISDN

COM ports”. You will see 5 more virtual modems in the selection list named “Internet
MLPPP”, “Internet MLPPP+BOD”, “Internet PPP over X.75”, “Internet MLPPP over
X.75”, and “Internet MLPPP+BOD over X.75” adapters. Select the appropriate virtual

modem to meet your ISP or RAS server requirement and select the ISDN Com port to
use with this modem. All of the other steps are the same as described in the Chapter 3.
The 128K/MLP Access is still available, but now you have more easy-to-use virtual
modem (adapter) to achieve 128K or 128K with BOD access goal.
