[Asterisk-Users] Re: Need to interface to BRIs

[Tim Petlock]

Does any Digium device generate the necessary timing?  If I have the
one-port FXO card present does that do the trick?  I bought the
developers kit with that one-port FXO card and the other FXS card with
provisions for four ports but hardware for one.

I'm trying to determine whether I should buy the 4-bri ISDN card from
Junghanns or start out with a 1 port CAPI card.  I know that a CAPI card
is not zaptel and the other is.  If I have the Digium FXO card present
along with a CAPI will that provide timing to my system?  My budget may
dictate that I go with a CAPI card to start out with - ISDN line
installations are not cheap to get in Uruguay.

There are a host of features, such as conferencing and music-on-hold
which require a hardware device for timing.  Not just any device will
work (it has to generate exactly 1000 cycles per second).
