I connect to Argo via ISDN at work using a PC or an SARPC.  The modem we
have is the external USR Robotics ISDN TA/33k Modem.  It work fine except
connections are limited to 64K as only one of the two ISDN channels can be
used at once - still, works fine if you want to be able to internet and
receive calls at the same time. - this modem did cost �200-�300!!

The modem plugs into the COM/SERIAL port as usual.  The alternative on PCs
at the moment is a TA (terminal adapter).  These invariably allow both ISDN
channels to be used at once thus allowing connections of 128K!!!!! - these
vary from �100 to �500

Look out for MODEM/ROUTER combinations which for about �300 allow upto 128k
connections, four machines to be plugged in via NICs and will automatically
switch one of the channels over for phone calls and then back to data when
the call has been finished - not having had a chance to try this on an Acorn
yet I can't say if they do work for us, no reason why they shouldn't though!
