since it's net3 i wouldn't worry about it being down unless you need to make
a call...get this:
config t
service timestamp debug datetime msec
end
sh ver | i IOS
sh run int bri2/0
debug isdn q921
debug isdn q931
term mon
isdn call int bri2/0 xxxyyy !whatever phone number
if it doesnt pick up a TEI from the switch and place the call then you have
to worry.

we also have a 2522 router with one port BRI card , we have 4 isdn lines, 3
of then are siemens, our region is asia and here we are using the basic-net3
switch type , the problem we are facing is that when we plugin our bri line
in 3640 router's bri port its layer 1 and layer 2 don't show up but at same
moment when we plug the same ISDN line into our 2522 router's bri port its
working fine and shows every thing alright,
