Introduction

1.1 Brief Description of the MicroLink ISDN/PCC-16
MicroLink ISDN/PCC-16 from ELSA's family of ISDN products is an expansion board for IBM Personal
Computers and compatibles. It allows your PC to be connected to an S0interface, making it suitable
for the operation with an ISDN Basic Rate Interface or a private automatic branch exchange equipped
with an S0interface.
CAPI interface The CAPI driver (Common ISDN Application Programming Interface, version
1.1 and 2.0) is a standardized software interface between your MicroLink
ISDN/PCC-16 and any standard ISDN communications software for fax group
4, data transfer, remote computing and file transfer.
FOSSIL interface The supplied FOSSIL (Fido/Opus/SEAdog Standard Interface Layer) driver
cFos allows non-ISDN, cFos-compatible communications programs (such as
Telix or Telix for Windows) to be used with your ISDN adapter board.
ISDN operation Using the CAPI interface, MicroLink ISDN/PCC-16 can transfer data at a speed
of 64,000 bps or 56,000 bps on each B channel. Both B channels (data
channels) can be used simultaneously.
Status display for
diagnostics The mounting bracket of your ISDN adapter board has two color-coded LEDs which allow you to monitor the ISDN interface and the line connection status.
These help with diagnostics and trouble-shooting if problems arise such as
errors in installing the ISDN interface.

◊NOTE ◊Make sure that the selected IRQ line is not used by any other device in your
PC, as a conflict may result in a malfunction of the ISDN adapter board. It is
common for IRQ2 and IRQ3 to be in use, and in some systems IRQ5 and IRQ15
can also be occupied.
2. Switching the Switch your PC off and unplug its power line from the power socket. This is
PC off very important for your safety!
3. Inserting the Remove the cover of the PC housing. Most PCs require some screws on the
adapter board rear side to be removed first, while others have a cover which opens up when
you press two locking buttons on both sides of the housing. Refer to the
manual of your PC for detailed instructions.
Select an empty slot of the required length, remove the blind bracket and
insert your the ISDN adapter board into the slot. If you are using an 8-bit slot
(MicroLink ISDN/PCC-16 only), you can only use the IRQ lines 2, 3 and 5. If
you are using a 16-bit slot, you can use any IRQ line (see table above).
Screw the mounting bracket of the ISDN adapter board tight, close the cover
of the PC housing. You can now reconnect your PC's power cable.
4. Connection to To connect your ISDN adapter board to the ISDN, plug the supplied cable
the ISDN into both the ISDN line connector in the mounting bracket of the board and
the S0wall socket of your ISDN line.
5. Switching the You can now switch your PC on.

Ready for operation The ISDN adapter board will be ready for operation after installing the card
and after successfully loading the driver software (see chapter 3, "ISDN Driver
Installation" for details). If the green LED in the adapter board's mounting
bracket is shining constantly, then your ISDN adapter board is ready for
operation and you can start your application software.

3 ISDN Driver Installation
Before starting with the installation of your ISDN adapter board, check which protocol your ISDN
connection uses. This information should have been supplied by your ISDN provider. In Europe, the
protocol Euro-ISDN (DSS1) is wide spread, though in Germany some lines still use the older 1TR6
national ISDN protocol. With Euro-ISDN, you will require information about the Multiple Subscriber
Numbers (MSNs) assigned to your ISDN line. In the USA, you should have information about your
SPID and DN.
3.1 Installation under DOS
Installing the CAPI driver for DOS is simplicity itself with ELSA COMman, the menu-driven program for
driver installation. Run COMman direct from the \ELSAWARE\COMMAN\DOS directory on the CD
supplied by starting INSTALLD.EXE and follow the on-screen instructions. Please note that the
README file contains important information for the driver installation.
The program carries out an automatic diagnosis, after which you can use Installation, ISDN
Settings, User-defined to define your parameters and phone numbers. The online Help is always
available with useful advice and information about the various parameters.
After successfully installing the ISDN drivers the computer must be restarted.

3.2 Installation under Window 3.x
Installing the CAPI driver for Windows 3.x is simplicity itself with ELSA COMman, the menu-driven
program for driver installation. Run COMman direct from the \ELSAWARE\COMMAN\WIN31
directory on the CD supplied by starting SETUP.EXE and follow the on-screen instructions. Please
note that the README file contains important information for the driver installation.
The program carries out an automatic diagnosis, after which you can use Installation, ISDN
Settings, User-defined to define your parameters and phone numbers. The online Help is always
available with useful advice and information about the various parameters.
If you plan to work exclusively with Windows communications applications, we recommend that you
activate the WINSTART.BAT option which ensures that the ISDN driver does not occupy any DOS
memory. If you wish to make use of communications programs from within DOS boxes, then you will
have to start the ISDN driver from the AUTOEXEC.BAT.
After successfully installing the ISDN driver, your computer should be restarted.
