This is my Linux hardware level driver for Teles compatible ISDN cards. It is meant to be used with isdn4isdn4linux, an ISDN Link-level module for Linux written by Fritz Elfert. Isdn4linux can be obtained from ftp.franken.de:/pub/isdn4linux. The most recent Teles driver can be found on my homepage, http://www.xs4all.nl:/~jdo. Warning ------- Teles4isdn4linux is a work in progress and may crash your machine. It has not been certified and therefore operation on your PTT's ISDN network is probably illegal. Limitations ----------- Teles4isdn4linux only works on Euro ISDN lines and german 1TR6-lines. For the B channel transparent (HDLC) protocol and X.75 have been implemented. Running ------- When you insmod isdn.o and teles.o (or with the kernel-version, during boottime) a few lines should appear in your syslog. Look for something like: Oct 11 16:53:30 jedi kernel: channels 2 Oct 11 16:53:31 jedi kernel: Teles module installed Remember, that according to the new strategy for accessing Low-level-drivers from within isdn4linux you should also define a driver-id while doing insmod: Simply append teles_id= to the insmod-commandline. This string MUST NOT start with a digit or a small 'x'! At this point you can run a 'cat /dev/isdnctrl0' and view debugging messages. Debugging messages are enabled with the telesctrl tool: teles/telesctrl 1 where is the integer sum of the following debugging options you wish enabled: 1 Link-level <--> Hardware-level communication 2 Top state machine 4 D channel Q.931 (call control messages) 8 D channel Q.921 16 B channel X.75 32 Lowlevel (irq and Layer1 stuff) For example 'teles/telesctrl MyTeles 1 63' enables full debugging.
