DPNSS runs over a D channel, just like most other ISDN related 
signalling protocols. However, DPNSS is a UK only protocol. It might be 
hard to get anyone outside the UK to take any interest in it.

Hi All,

I dont know too much about the technical specs on DPNSS, but can
support for it be developed in software, like libpri ?

I guess what I am asking is, if DPNSS is just another
signalling protocol, I suppose it can be built using software,
as a layer over zaptel  using a digium digital E1 card.

Unless, there is something about the physical nature of the
signalling, that would require different hardware ??

If its possible, has anyone thought about how to go about doing it ?

Thanks

You are right about that.

However, if there is anyone on this list who
has any thoughts on how this can be done,
could you please contact me OFF list
to exchange ideas ?

Thanks
