if you didn't need the the simulated telco switch d-channel, then your best bet would be to use a PBX system. in other words, if you simple needed the lines to be circuit switched like a isdn cloud would do without the actual isdn protocols.
this is basically putting in an NT2, but bypassing any need for a NT1 by not having any real outside isdn service. scott ""Howard C.
