In most cases, the ML installer will recognize your ISDN card correctly,
and you'll be able to set up your connection with a snap. If not, here are the
gory details ;-).
This article describes a setup for syncPPP, which is used by most providers
today. asyncPPP is set up just like any other PPP
dial-up, the only difference being the device file: it's not /dev/ttyS[x]
but /dev/ttyI[x].
These are handled exactly like modems. Please refer to the Dial-up Networking (PPP) pages.

You will find a list of supported cards in the isdn4linux FAQ, Section 5.1
in '/usr/share/doc/isdn4k-utils-[version]/'. If you are considering buying a
new card, read Section 5.10 as well. An online version of this FAQ is
available on the ISDN4Linux website,
there is also a German
version.

You will need the isdn4k-utils-[version].rpm, which provides the basic
infrastructure (device files, binaries) and the isdn4net-[version].rpm, which
provides the configuration scripts and some documentation. Most probably they
are already installed.
You have to edit five files:
- '/etc/isdn/profile/link/myisp', your dial-up profile
- '/etc/isdn/profile/card/mycard', your hardware profile
- '/etc/ppp/pap-secrets' or '/etc/ppp/chap-secrets', your password file
- '/etc/resolv.conf', the DNS data file
- '/etc/rc.d/rc.local', your start-up batch file
'/etc/isdn/profile/link/myisp'
To make things easier, I will only mention values you have to change.
I4L_USERNAME="[enter your dial-up account name]"I4L_SYSNAME="[just delete the word 'linuxisp']"I4L_LOCALMSN="[the number from which you are calling]"I4L_REMOTE_OUT="[the number of your provider]"I4L_DIALMODE="[change to 'auto' if you want to use
dial-on-demand]"
'/etc/isdn/profile/card/mycard'
This is a little bit more difficult ;-). I will only mention values you
have to worry about.
I4L_ID="Teles1"
This value is arbitrary. Leave it or change it to something you like.
I4L_DEBUG=4
Set this number higher for more verbose error messages. For the time being
it will do.
# kernel module to use (teles, hisax, icn, pcbit)
I4L_MODULE="hisax"
Different cards require different modules. To find out which module you
need, go to '/usr/src/linux/Documentation/isdn', if the kernel-sources.rpm is
installed, or to '/usr/share/doc/kernel-doc-[version]/' (if kernel-doc is
installed). If you have none of these directories, install the kernel-doc.rpm
from your Mandrake CD.
Being in the isdn directory, use grep to find the appropriate
README file for your card, e.g.:
grep Fritz! *
README.HiSax: 26 AVM A1 PCMCIA (Fritz!) irq, io (set with card manager)
README.HiSax: 27 AVM PnP (Fritz!PnP) irq, io (from isapnp setup)
README.HiSax: 27 AVM PCI (Fritz!PCI) no parameter
README.HiSax: 26 AVM A1 PCMCIA (Fritz!) pa=irq, pb=io (set with card
manager)
README.HiSax: 27 AVM PnP (Fritz!PnP) ONLY WORKS AS A MODULE !
README.HiSax: 27 AVM PCI (Fritz!PCI) no parameter
So the name of the module for this card is 'hisax'.
I4L_TYPE=3
Set this number according to the type of your card listed on the bottom of
the file.
I4L_IRQ="10"
I4L_MEMBASE="0"
I4L_PORT="0xd80"
Now comes the fun part :-). Check the list at the bottom of the file, it will
tell you how many parameters you have to specify. If your ISDN card is a PCI
card, you don't have to worry about settings at all, just erase the preset
values:
I4L_IRQ=""
I4L_MEMBASE=""
I4L_PORT=""
and you'll be fine.
If you're using a 'Plug-and-Play' ISA card, run the 'Hardware
Configuration' tool from 'DrakConf'. If your card shows up, open the file
'/etc/isapnp.conf' and take the values of your card from there.
If this doesn't work or if your card is not 'Plug-and-Play', you have to find
out about these values on your own.
- Have a look at the appropriate README file in the 'isdn' directory. It
lists defaults values for the most popular non-PCI cards.
- Read the documentation that comes with the card.
- Visit the tech support section of the manufacturer's website.
- If you are dual-booting with MS-Windows, get the values from its 'Hardware
Manager' ('System').
- If your card has come with a driver disk, read the '.inf' file.
- Search Google for Usenet messages
about your card.
As soon as you've got the values, test them with modprobe:
modprobe [modulename] io=[value] irq=[value] mem=[value] type=[value
(see above)] protocol=[value] id=[value]
If you don't get any complaints from modprobe, append the
complete line to the file '/etc/rc.d/rc.local'.
/etc/ppp/pap-secrets or /etc/ppp/chap-secrets
Enter your account name and the password your provider has given you. If
you don't know, whether your provider uses CHAP or PAP for authentication,
enter these values in both files:
# Secrets for authentication using PAP
# client server secret IP addresses
[account name] * [password]
If either of these values contains spaces or unusual characters (like @ or
#), enclose it in quotes.
/etc/resolv.conf
Enter the name of your provider and the addresses of his DNS servers here.
If you don't have these addresses, kindly ask him to provide these, you need
them:
search localdomain <--- leave this entry alone
domain [name of your provider, e.g. provider.com]
nameserver 212.122.128.10 <--- example
nameserver 212.122.129.10 <--- values
If you make a mistake here, you won't be able to go anywhere on the
'Net.

Yep, we're already there :-). As root, (re)start isdn4linux with:
service isdn4linux restart
Bring up the new interface with
ifup ippp0
Now dial!
isdnctrl dial ippp0
Open a browser and browse away ;-).
Hang up with isdnctrl hangup ippp0.
Append the line ifup ippp0 to the file '/etc/rc.d/rc.local'.
