Hi there,

here some more up-to-date snippets concering ISDN that you might want to 
include:

you can use the AVM Fritz card in P2P mode, if you use the new mISDN
capi layer with chan_capi. You dont have to rely on a kernel-tainting
module anymore.
Of course it makes sense to use a hfc-pci card instead, since it will
provide your box with zaptel timing and echo cancelation!

PTP: Point-to-Point (usually goes along with DDI)
PTMP: Point-to-Multipoint

Don't forget about the (new) chan_misdn:
