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.

operation and you can start your application software.

ISDN Driver Installation

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

ISDN Driver Installation

Notes:

Operation in AT Mode

4 Operation in AT Mode

The AT command set, well known in the world of analog communications, can be used in ISDN

communications with the help of the FOSSIL driver cFos/DOS Lite, included in your package, when

used with a DOS terminal program supporting INT 14 or FOSSIL output.

With the driver cFos/WIN Lite, common Windows data communications software such as Telix for

Windows can be used with ISDN adapter boards. The cFos driver enables the use of virtual COM port

emulation under Windows 3.1, meaning no additional FOSSIL- or INT 14 mode software is necessary.

4.1 Installing the cFos Driver

To install cFos on your computer, please proceed as follows:

1. Insert the CD or floppy disk into the appropriate disk drive. If you are

installing from CD, select the directory for your adapter board, i.e.

MICROLINK\PCC16\DRIVER\ CFOS.

2. Enter the command

install <CR>

to start the installation. Choose the language you wish to work with.

3. Either accept the suggested target directory for the installation or enter

the path of your choice. Confirm your entries with <CR> and follow the

program instructions.

If you require cFos for COM port emulation under Windows 3.x or

Windows 95, call SETUP and follow the program instructions. To

enable the automatic loading of cFos when Windows starts, the

changes to the file WIN.INI must be confirmed with Yes (the computer

will be started anew).

If you have problems during installation, please refer to the file

README.WIN.

4. After the installation is ended, start the configuration program with

<CR> and choose the desired language.

5. The final step is to run the Software Adjustment program. Confirm

the ELSA modem settings (the program knows these already!) with Yes

and choose the software (e.g.Telix) that you will be using. Finish the

configuration with = and exit the program with End.

Operation in AT Mode

4.1.1 Starting cFos

Requirements for

cFos Before starting cFos, you must first load the required CAPI driver. To start

cFos in DOS, call the file STARTFOS.BAT from the cFos directory, or enter

cfos i <CR>

Entering STOPCFOS.BAT will stop cFos, as will the alternative

cfos d <CR>

In Windows, cFos is automatically started if the WIN.INI file was updated

during installation.

◊NOTE ◊To load these drivers automatically at startup, these drivers can be called from

the AUTOEXEC.BAT

cFos does not support the same AT command user interface as ATCAPI. Thus, some

AT commands familiar to ATCAPI users may not be recognized or executed. Please

refer to the cFos driver documentation. Further information to this subject is to be

found in the files CFOS.DOC, MODEM.DOC AND CFOS.FAQ.

The following options, or combinations thereof, are available:

4.2 General

AT command set The AT command set has established itself as the world-wide standard for

modem control command syntax (AT = command prefix ATtention).

Two operating states The two general operating states of the ISDN adapter board in the AT mode

are the command state and the online state (transmission state).

Command input,

execution After the drivers have been loaded, the ISDN adapter board is in the

command state. Commands can be accepted, interpreted and executed in

this state only. After a successful connection with the other party, the ISDN

adapter board automatically changes to the online state.

Data transmission Online state signifies that a connection to another party exists. The ISDN

adapter board is "online", either with a successful connection (outgoing call)

or with the acceptance of an incoming call. In this state data exchange is

possible between the two connected stations.

Operation in AT Mode

4.2.1 Entering AT Commands in a Terminal Program

If you want to use the AT command set known from analog modems, you must load a suitable FOSSIL

(Fido/Opus/SEAdog Standard Interface Layer) driver, e.g. cFos, in addition to the CAPI driver. The

cFos/DOS driver shipped with your ISDN adapter board allows the use of communications programs

supporting Interrupt14h or FOSSIL output (such as Telix or Telix for Windows) and must be loaded in

addition to the CAPI 1.1 driver. The FOSSIL driver emulates the AT command interface in order to

allow FOSSIL-supporting communications programs, which are normally used with analog modems, to

work directly with ISDN adapter boards.

We will use Telix as an example to demonstrate how to enter AT commands in a terminal program.

For operation with your ISDN adapter board, Telix must be set to INT14 mode. This is a special mode

in which Telix directs data output not to the serial COM port, but via the BIOS interrupt 14 which

enables the use of passive ISDN adapter boards via suitable driver software. Note that Telix versions

older than 3.50 do not support the INT14 mode (except for Telix INT14, a special variant of Telix 3.15,

which works in INT14 mode only).

The cooperation between Telix and the ISDN adapter board can be shown as follows:

Telix for DOS (INT14 Mode)

Communications Program Telix sends your AT commands to the

FOSSIL driver cFos using the BIOS

interrupt 14h.

4.2.2 Instructions for Your First ISDN Connection under DOS

To establish a test connection, for example to our Support BBS ELSA ONLINE, please proceed as

follows:

nStart the CAPI driver DSS1CAPX.EXE (for Euro-ISDN), US__CAPX.EXE (for US protocols) or

ISDNCAPX.EXE (for 1TR6).

nStart the FOSSIL driver cFos by calling STARTCFOS.BAT or by entering cfos i.

nStart Telix and enable the INT14 mode. The COM port must be set to COM 2. This port is the

default link to the FOSSIL driver via the interrupt 14h (if you have started cFos with a different

port setting, you must set this port in Telix as well). In INT14 mode the COM ports are not

related to physical serial interfaces, therefore you need not set any bit rate or data format. In

ISDN operation, Telix always uses the highest possible bit rate.

nTo establish the connection, type ATD 0241 9177 7800 (from within Germany, otherwise enter

your international access code (+49) and omit the first 0) in terminal mode and press <CR>. Telix

will establish an ISDN connection with the Support BBS ELSA ONLINE. You can terminate the

connection at any time with the Telix command <Alt><H>.
