Please note, that you'll have to use modules for more than two cards, to pass all arguments. As an example, you can load HiSax for two Sedlbauer cards with the following command: <HR> <PRE> modprobe -v hisax protocol=2,2 type=28,28 </PRE> <HR> </LI> <LI>Driver ID: the HiSax driver uses 'HiSax' as the default for a driver id if you have only one card.

It is unlikely you have more than 64 physical B channels available, therefore you probably want to leave ISDN_MINOR_B and ISDN_MINOR_BMAX as they are.</P> <P>Your bottleneck are probably the number of potential (logical) network connections (ipppX devices). The maximum number for this (ISDN_MAX_CHANNELS) is 127, since the minor devices start at 128 (see ISDN_MINOR_PPP) and have to end before 255 (ISDN_MINOR_STATUS).</P> <P>To further increase the maximum number of logical connections you either have the possibility to use an additional major (e.g. 44 - not used any more) - this requires some small changes to the driver and the installation of one ipppd instance per logical connection; or to use only one ipppd per physical B channel with external Radius authentication. In the first case you have to modify and recompile the driver, in the second case you have to modify and recompile ipppd (you'll find some preparations for this already in the source code).</P> <P>Don't forget to create the additional devices with makedev.sh (part of isdn4k-utils) or by hand.</P> <H2><A NAME="config_gsmv110"></A> <A NAME="ss6.12">6.12</A> <A HREF="i4lfaq.html#toc6.12">config_gsmv110: How do I connect my PalmPilot via GSM over V.110 to my computer? </A> </H2> <P>A connection via GSM will first go to the GSM provider via a special air transmission protocol. To forwarding the data on to an analog or ISDN line, an adapter called IWF (interworking function) has to translate this into the analog or ISDN specific transmission protocol. Which analog or ISDN transmission protocol is being used depends on how the mobile phone requests its GSM connection. An analog connection is not very attractive due to the lengthy modem handshaking on dialin. For ISDN, HDLC and X.75 are currently not supported by the IWF, so the choices are down to V.110 and V.120. V.120 has better flow control and error correction, but currently isdn4linux only supports V.110.</P> <P>On the dialup server set up async PPP with a normal pppd on a ttyI* device (sync ppp will not work). Additionally to setting the msn, you have to set V.110 and the transmission rate to 9600 with <CODE>AT&R9600</CODE> (<CODE>/usr/src/linux/Documentation/isdn/README</CODE> gives more details on the V.110 bitrate adaption for this command). Switch off autoanswer with <CODE>ATS0=0</CODE> if you use mgetty. pppd needs to be called with <CODE>noccp</CODE> and <CODE>require-pap</CODE>.</P> <P>On the GSM mobile phone side, request an ISDN V.110 connection with the command <HR> <PRE> AT+CBST=71,0,1+CHSN=1,0,0,0 </PRE> <HR> For a Nokia 7110, you may have to use the undocumented command <HR> <PRE> AT+CBST=75,0,1 </PRE> <HR> </P> <P>If the bearer capability is reported as "88 90 21 48 06 bb" by isdn4linux, then you have set it correctly (88 90 21 means V.110, 48 means ASYNC 9.6kbit, 06 means flowcontrol RX/TX, bb means 8 bit 1 stop none parity).</P> <P>If the call is indicated with service indicator byte 2 = 0 and not accepted (happens with some wrongly configured PBX), then adjust with <CODE>ATS19=0</CODE>.</P> <P>A higher bandwidth of 19.2kbit (HSCSD) could be requested with the command <HR> <PRE> AT+CBST=81,0,1+CHSN=3,0,0,0 </PRE> <HR> but you can not be sure that your GSM provider will really use this rate. Configure your dialin server accordingly.</P> <P>For a mini-howto see: <A HREF="http://www.oltom.com/Linux/Docs/GSM%20over%20V.110%20Mini-HOWTO.txt">http://www.oltom.com/Linux/Docs/GSM%20over%20V.110%20Mini-HOWTO.txt</A></P> <H2><A NAME="config_h323"></A> <A NAME="ss6.13">6.13</A> <A HREF="i4lfaq.html#toc6.13">config_h323: How do I configure isdn4linux to act as a voice-over-ip gateway for H.323 clients? </A> </H2> <P>You have to install a gateway which handles the translation. Several versions exist which are all based on the OpenH323 and PWLib libraries. The latest recommendation is to use isdngw at: <A HREF="http://www.gnugk.org/h323-isdn-gw.html">http://www.gnugk.org/h323-isdn-gw.html</A>. This is an updated version of the isdngw located at: <A HREF="http://www.virtual-net.fr/h323/isdngw/">http://www.virtual-net.fr/h323/isdngw/</A>, which in turn is an updated version of the Linux H.323 - ISDN Gateway found on <A HREF="http://www.telos.de/linux/H323/">http://www.telos.de/linux/H323/</A>.</P> <P>Please note that not all sound cards support full duplex audio.

You can switch HiSax into point-to-point mode: <HR> <PRE> hisaxctrl <driver_id> 7 1 </PRE> <HR> Additionally, you can use the "AT&Lxxx$dquot; command to configure the range of telephone numbers isdn4linux should be listening to on the ttyI* devices.</P> <P>If you really absolutely want to run your ISDN card for read-only purposes in parallel to your pbx on a point-to-point connection, then you have to disconnect the RX leads (pin 3 and 6 on western plug), so that the NTBA will not see the ISDN card. In this case configure HiSax normally, NOT in point-to-point mode.</P> <H2><A NAME="config_links"></A> <A NAME="ss6.15">6.15</A> <A HREF="i4lfaq.html#toc6.15">config_links: What helpful links are there about and around isdn4linux? </A> </H2> <P>These are helpful links that are currently available on how to configure isdn4linux: <UL> <LI>English: <A HREF="http://www.wurtel.cistron.nl/i4l-howto-uk.html">http://www.wurtel.cistron.nl/i4l-howto-uk.html</A></LI> <LI>Dutch: <A HREF="http://www.wurtel.cistron.nl/i4l-howto-nl.html">http://www.wurtel.cistron.nl/i4l-howto-nl.html</A></LI> <LI>German: <A HREF="http://www.franken.de/users/klaus/">http://www.franken.de/users/klaus/</A></LI> <LI>French: <A HREF="http://www.linux-france.org/article/connex/ISDN/">http://www.linux-france.org/article/connex/ISDN/</A> and <A HREF="http://www.linux-france.org/prj/inetdoc/guides/rnis/">http://www.linux-france.org/prj/inetdoc/guides/rnis/</A></LI> <LI>Suse Support database: <A HREF="http://sdb.suse.de/sdb/en/html/index.html">http://sdb.suse.de/sdb/en/html/index.html</A>; there is also an ISDN howto (isdn.html) and a ISDN quick-install guide (isdnquick.html).</LI> <LI>Tips to configure Suse (and about offline reading): <A HREF="http://www.schlenn.de/isdn4linux/">http://www.schlenn.de/isdn4linux/</A></LI> <LI>Tips to configure Red Hat: <A HREF="http://www.webideal.de/rh-isdn/">http://www.webideal.de/rh-isdn/</A></LI> <LI>Tips to configure Debian with Fritz Card PCI and kernel 2.6 (in German): <A HREF="http://www.plzk.de/archiv/files/docs/FritzCard.PCI.Linux-HOWTO.html">http://www.plzk.de/archiv/files/docs/FritzCard.PCI.Linux-HOWTO.html</A></LI> <LI>Tips to configure Mandrake: <A HREF="http://www.mandrakeuser.org/connect/cisdn.html">http://www.mandrakeuser.org/connect/cisdn.html</A></LI> <LI>Tips to configure Gentoo: <A HREF="http://forums.gentoo.org/viewtopic.php?t=29991">http://forums.gentoo.org/viewtopic.php?t=29991</A> <A HREF="http://de.gentoo-wiki.com/ISDN">http://de.gentoo-wiki.com/ISDN</A></LI> <LI>fli4l, a prepackaged Linux version to use an old PC as ISDN router: <A HREF="http://www.fli4l.de">http://www.fli4l.de</A> (great!)</LI> <LI>LR101 (a project which tries to create a hardware router based on Linux): <A HREF="http://lr101.linux-it-solutions.de">http://lr101.linux-it-solutions.de</A></LI> <LI>Scripts and installation tips from several people: <CODE> <A HREF="http://www.rosat.mpe-garching.mpg.de/~web/ISDN.html">http://www.rosat.mpe-garching.mpg.de/~web/ISDN.html</A></CODE></LI> <LI>Documentation on abc extensions: <CODE> <A HREF="http://i4l.mediatronix.de/">http://i4l.mediatronix.de/</A></CODE></LI> <LI>Installation of CAPI4LINUX, CAPI4LINUX, and CAPI4Hylafax (in German): <CODE> <A HREF="http://ixi.thepenguin.de">http://ixi.thepenguin.de</A></CODE> or <CODE> <A HREF="http://capi4linux.thepenguin.de">http://capi4linux.thepenguin.de</A></CODE> or <CODE> <A HREF="http://www.thepenguin.de">http://www.thepenguin.de</A></CODE></LI> <LI>Vbox development: <CODE> <A HREF="http://innominate.org/projects/vbox/index.php3">http://innominate.org/projects/vbox/index.php3</A></CODE></LI> <LI>Michael Hipp's page (general informations): <CODE> <A HREF="http://www-ti.informatik.uni-tuebingen.de/~hippm/isdn.html">http://www-ti.informatik.uni-tuebingen.de/~hippm/isdn.html</A></CODE></LI> <LI>Chargeint tips: <CODE> <A HREF="http://www.auf-der-er.de/chargeint.html">http://www.auf-der-er.de/chargeint.html</A></CODE></LI> <LI>Homepage of linecontrol (manage isdn dialing similar to kisdn): <CODE> <A HREF="http://linecontrol.sourceforge.net">http://linecontrol.sourceforge.net</A></CODE></LI> <LI>(German) Homepage of ISDN Sniffer (read ISDN bus, e.g. via reversed card): <CODE> <A HREF="http://krypt.cs.uni-sb.de/projects/isdnsniffer/">http://krypt.cs.uni-sb.de/projects/isdnsniffer/</A></CODE></LI> <LI>Homepage of Asterisk (Open Source Linux PBX): <CODE> <A HREF="http://www.asterisk.org">http://www.asterisk.org</A></CODE></LI> <LI>Homepage of ivcall (send and receive fax/voice calls): <CODE> <A HREF="http://0pointer.de/lennart/projects/ivcall/">http://0pointer.de/lennart/projects/ivcall/</A></CODE></LI> <LI>Configuration software maKs for Ackermann Euracom (not isdn4linux related): <CODE> <A HREF="http://www.ganzfix.de">http://www.ganzfix.de</A></CODE></LI> </UL> </P> <H2><A NAME="config_misdn"></A> <A NAME="ss6.16">6.16</A> <A HREF="i4lfaq.html#toc6.16">config_misdn: How should I configure the new mISDN driver, and what is so special about it? </A> </H2> <P>The mISDN driver stands for modular ISDN. It is a complete rewrite of the old isdn drivers and now communicates via CAPI messages. The mISDN driver is retire the historical drivers once it is fully functional within the 2.6.x kernels.

You still have to create all the devices you need, either with makedev.sh (part of isdn4k-utils), or by hand.
