Just to announce some success I've had with ISDN, which may be of
interest considering the number of emails relating to ISDN that have
cropped up on this list recently...
The location is a secondary school in the county of Lincolnshire in
England, for which I spent the summer networking their computers and
organising an Internet connection using the "Schools Internet Caller"
service offered by British Telecom to UK schools.
The system in question is Intel P133 based, and has a USR Courier
I-Modem installed, and this card didn't even need the kernel
recompiling with ISDN support to work under Linux as it pretends to be
a standard analogue modem as far as the rest of the computer is
concerned. Its 'serial port' id's as a 16550 but has no problems
providing or accepting data at nearly 18k per second, as regularly
appears to happen, and the ISDN circuitry on the card does automatic
transparent channel bunching, which the ISP at the far end of the link
supports.
My only question relating to this is because I have no other
experience of ISDN, hence I have to ask whether there are any known
problems we're likely to meet with this configuration?
Best wishes from Riley.
