None to my knowledge, apart from the instructions in the package.

Yes, unless you have a hfc-s based card that does power the line (I
don't think they exist) Just follow the documentation at
http://isdn.jolly.de/ to wire up your card, your NT1 and your phone
equipment.

To load the card(s) in nt1 mode you'll need to give a 'modes' option
when loading the driver:

insmod ./zaphfc.o modes=1
 (first card in NT mode)
or
insmod ./zaphfc.o modes=3
 (first and second card in NT mode)

Note that when using more than one card, the module will segfault when
unloading:

zaphfc: stop
zaphfc: shutting down card at e0962000.
unregistered from zaptel.
zaphfc: freed one card.
zaphfc: shutting down card at 00000000.

... and you'll be stuck with a half removed module. The only cure I've
found thus far is rebooting.

When configuring zaptel, you'll need to load the zaphfc driver before
any wcfxs or wcfxo drivers, as the zaphfc channels are loaded as a span.

All in all, the driver is 'sort of' working, 'sometimes'. I have
dialtone disappearing from the ISDN phones regularly, only restart of
asterisk brings it back. To be fair, the configuration of this setup has
not had any real priority, and no real debugging has been done.

when picking up the handset on one of the phones, I allways get the
following message in the console:

Feb 17 21:02:07 WARNING[147466]: chan_zap.c:5954 zt_pri_error: PRI: XXX
