Installation
Chapter 2 - Introduction
This chapter describes how to make all the physical and software driver connec-
tions nescessary in order for your terminal adapter to operate in an ISDN environ-
ment. Before installing your terminal adapter, check the package contents (see
section 1.2.1 in Chapter 1 for package contents list).
For an NT1 device (MT128ISA-UD or MT128ISA-UV adapter[s] only), order an
ISDN BRI line and get an Internet access account (if Internet access is required);
this is advisable to start your environment setup before actually installing your
ISDN adapter.
2.2. ISDN BRI Line
Before running the ISDN adapter, you need to get an ISDN BRI (Basic Rate Inter-
face) line from your local telephone company. Sometimes, your ISP may, upon
your request, order an ISDN BRI line for you when you apply for an ISDN Inter-
net 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 (applicable in the United States).
2.2.1 SPID (Service Profile ID)
The Service Profile ID (SPID) is applicable in the U.S. only. SPIDs are a series of
numbers that informs the central office switch which services and features to pro-
vide to an ISDN device. The generic SPID format comprises of 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 sup-
port.
2.2.2 NT1 Connection
An ISDN Basic Rate (BRI) U-Loop is 2 conductors from the CO (telephone com-
pany central office) to the customer premises. The equipment on both sides of the
U-loop has to be carefully 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 termi-
nated by an NT1 (network termination 1) device. An NT1is a device which pro-
vides an interface between the two-wire twisted-pairs used by telephone companies

12-IWay Hopper
Installation
in their ISDN BRI network and an end-user's four wire terminal equipment. The
NT1 drives an S/T-bus which is usually 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, Sand T. Point Trefers to the connection between the
NT1 device and customer supplied equipment. Terminals can connect directly to
NT1 at point T, or there may be a PBX (private branch exchange, i.e. a customer-
owned telephone exchange). When a PBX is present, point Srefers to the connec-
tion 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 below reflects interface points in a
typical ISDN network.
If your ISDN product operates with a S/T outlet interface, you need an NT1 device
connect to the ISDN switch. MT128ISA-SD/SV adapter needs an NT1 device to
connect to the ISDN switch, but MT128ISA-UD/UV 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 adapters are required for these coun-
tries.
Figure 2-1 ISDN Interface Points
2.2.3 Internet Access
If you want to use an ISDN adapter to connect to the Internet, you must get an
Internet access account from an ISP (Internet Service Provider) in your country.
You must also confirm with your ISP that they support ISDN access (either single
channel 64K or 128K MLP).

Installation
2.2.4 Safety Warnings
4Never install telephone wiring during a lightning storm.
4Never install a telephone jack in a wet location unless the jack is specifically
designed for wet locations.
4Never touch uninsulated telephone wires or terminals unless the telephone line
has been disconnected at the network interface.
4Use caution when installing or modifying telephone lines.
4Avoid using a telephone (other than a cordless type) during an electrical storm.
There may be a remote risk of electrical shock from lightning.
4Do not use the telephone to report a gas leak in the vicinity of the leak.
4Ports that connect to other apparatus are defined as SELV. To ensure confor-
mity with EN 41003, ensure that these ports connect only to the same type of
port on the other apparatus.
2.3 Environment Setup
All ISDN adapter models are Plug and Play (PnP) compatible. Even if the BIOS
or computer main board does not provide PnP feature support, the device driver
still can automatically configure ISDN card with proper I/O addresses and IRQ
number.
2.3.1 Terminator Setup
1. Disregard step 1 for models MT128ISA-UD/UV only, and proceed to step 2.
The ISDN S/T interface can support up to 8 ISDN terminals and NT1 devices
connecting to the ISDN network. 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. The MT128ISA-SD/SV adapter(s) pro-
vides two jumpers (JP1 and JP2) for the terminators setup. The default setting
for the MT128ISA-SD/SV adapter(s) is terminator enabled. If there are other
ISDN devices connected to the NT1 with MT128ISA-SD/SV adapter(s), and
you do not require the MT128ISA-SD/SV adapter(s) as terminator, then re-
move the JP1 and JP2 shorting plugs (open circuit).

After you setup your ISDN environment, turn your computer power ON and start
the driver installation. Your ISDN adapters support Microsoft Windows environ-
ments; read the appropriate installation section for your PC system.
2.4.1 Windows 3.1 Installation and Driver Configuration
You can configure your ISDN connection via COM port emulation, standard
WinISDN interface, or standard the CAPI 2.0 interface in Windows 3.1.
Follow these steps:
1. Insert the ISDN installation CD/diskette into the disk drive.
2. Select the File menu from the Program Manager, then choose the Run item to
execute the SETUP.EXE file on the disk drive. The installation software will
automatically process the necessary setup steps.
3. ISDN Configuration. After step 2, setup automatically displays the ISDN
Configuration dialog box (see figure 2-4). Fill the necessary information in
the text boxes of ISDN Configuration dialog box.
Figure 2-4. ISDN Configuration Display

17-IWay Hopper
Installation
3a. ISDN Switch Type. Choose the country name for your location, or select an
appropriate ISDN switch type in your country (especially for U.S. customers).
3b. Codec. Countries adhering to the European telecommunication standard may
choose A-Law. Countries adhering to the U.S. telecommunication standard
may choose u-law.
3c. Standby Time. This is a timer which buffers any keypads input from an analog
device before sending a message out. Do not change the default value.
3d. MSN (POTS). This parameter is used for ISDN switches supporting MSN
(Multiple Subscriber Number) service. MSN service is supported by some
European telephone companies. If you enter the number here, the called tele-
phone number of an incoming call will be required to match the MSN (POTS)
value, otherwise the analog device connected to the POTS (a/b) port will not
be enabled.
3e. SPID-1 and SPID-2. SPID parameters only need to be setup for certain U.S.
customers; please check with your telephone company if this is your require-
ment.
4. ISDN adapter installation is complete. Restart Windows. The ISDN driver will
be automatically loaded after re-starting Windows 3.1, and the ISDN Group
Folder appears as shown below.
Figure 2-5. ISDN Group Folder

18-IWay Hopper
Installation
The ISDN LOG application is used to record the handshaking and data transfer
process during communication. It can be used for debugging purposes so it is
useful to have the log running while first starting to use the ISDN system. The
Line Diagnostic is used for on-line channel testing between the ISDN switch
and subscriber site, and getting ISDN line status. Please refer to Chapter 4 for
detailed information.
5. You can re-configure the parameters of step 3 by executing the ISDN Configur-
er in the ISDN Group Folder. The Configuration dialog box also displays the
I/O address and IRQ value in the message bar.
2.5 Application Interface Setup
Under Windows 3.x applications, you can configure your terminal adapter device
using either COM port emulation, the standard WinISDN interface, or the CAPI
2.0 interface.
1. COM Port Emulation. The ISDN driver provides AT command set interpreter
to emulate modems and transfer/receive data through the ISDN network. You
must set up your application software to the appropriate COM ports (COM3 or
COM4) to communicate with the ISDN adapter. The AT Console program
(see Figure 2-5) can redirect the AT commands and data through COM3 or
COM4 to the ISDN driver to process them.
 If you want to set up an Internet connection through COM port emulation,
TRUMPET is a popular Internet shareware and includes the TCP/IP and PPP
protocols with Winsock interface. Many Windows 3.1 Internet modems use
TRUMPET to connect to the Internet and to run Internet applications such as
Netscape Navigator. TRUMPET users should modify the Network Configuration
and Script files to access the Internet through terminal adapters. See Appendix B
for an example of a setup modification for TRUMPET.
 When entering Windows 3.1, you must run the AT Console to enable the COM
port emulation capability.
 Multilink PPP is not supported at the AT Console. You may get a Multilink
PPP connection through the applications which include a TCP/IP and Multilink
PPP stack with WinISDN or CAPI interface.

19-IWay Hopper
Installation
2. WinISDN Interface. The ISDN driver can transmit/receive data with applica-
tions through the standard WinISDN interface. The following TCP/IP stacks
support the WinISDN interface.
 NetManages Chameleon
 FTPs Explore
 Frontiers SuperHighway Access
Refer to the proper TCP/IP stack document respective to your setup dial-up envi-
ronment 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 card for up to 128K
data transmission and receiving through the standard CAPI 2.0 (or later) inter-
face.
 Removing ISDNLINK for Windows 3.1
To remove the ISDN driver from your Windows 3.1, click the unInstallSHIELD
icon (see Figure 2-5).
2.5.1 Windows 95 Installation
Read the following Windows 95 installation steps and setup procedures for NDIS-
WAN Miniport adapters and virtual modems.
1. After you have installed the internal PC terminal adapter, switch computer
power on and allow Windows 95 to startup. When the system starts it should
auto-detect a new PnP card and request driver installation. Insert the ISDN
driver diskette/CD into appropriate disk drive, select the ISDN100.INF file
from the installation diskette/CD. Windows 95 automatically processes the
necessary installation steps.
2. With Windows 95 you can set up (or change) the ISDN configuration of Switch
Type, values of MSN and SPIDs by:
Double Clicking on Settings»Control Panel»System»Device Manager»ISDN
LinkCard»ISDN MT128ISA Adapter»ISDN MT128ISA Adapter
Properties»Settings.

20-IWay Hopper
Installation
Figure 2-6. ISDN Adapter Properties
Configuration in Windows 95 is similar to the installation in a Windows 3.1 envi-
ronment. The MSN (POTS) value is only relevant to Vmodels 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
ring on a call coming in to the number 341317). For the UK and most European
countries, the EURO ISDN switch type with A-law Codec is selected. If you want
your analog device always ringing when receiving an incoming call, keep this field
blank.
3. Reboot Windows 95 after configuring the switch type. After restarting Win-
dows, DV models can connect to a standard analog telephone set and should
be able to hear the dial tone from the telephone handset.
