Well, my window of opportunity to get this going is rapidly diminishing, 
although I'll have tomorow morning as well - however I can't get it to 
work.

Although the channels looks like they're up:

dsx*CLI> dahdi show status
Description                              Alarms     IRQ        bpviol     CRC4

(only 3 lines connected)

I get lots of logs complaining about unable to find the D channel and 
dialling out yields CHANUNAVAIL calling in gives BTs digital dot telling 
me it's temporarily out of order, so giving up and going back to my old 
mISDN and asterisk 1.2 setup...

Ah well, I'll come back to in in 2 years time I guess when I'm looking at 
1.8...
