asterisk users - Feb 2007 - Howto use PRI lines (E1 or T1) for "data calls"?

Hi,

I'm looking for a mean to send digital data over
an E1 line, just like isdn4linux or Capi via AVM's FritzCard
is able to do it with BRI lines (e.g. for PPP or ISDN raw
connections).

I'm not looking for modulated audio data representing
digital data, like fax or the analogue modems of former
times. I want an interface to the ISDN raw data, with
an outgoing call marked as "data", not "voice".

Best would by the behaviour of /dev/ttyIx.
Thus I thought about iaxmodem.
Could please anyone tell me, whether it is possible to
make an ISDN "data call" using

iaxmodem <----> asterisk <----> ISDN PRI line

?


Thanks for any hint!

Roger.

point to point E1 lines?  Or are you interfacing to a PSTN network for
local calling/receiving?

Hi,

yes, PSTN. Normal operation is ordinary voice.

Hm, the "hybrid configuration" mentioned in your link
may serve as a workaround anyway. I should read this further.


Thanks for the hint!
