DID is delivered one of two ways: on a specialized analog trunk,
suitable to be terminated by, e.g., a Dialogic DID-120 card (this is
fairly rare these days, and only seen on *old* legacy installs) or on a
D-4/ESF T-span (or an ISDN PRI).

The signalling is commonly DTMF on the analog or T-1 trunks, between
the offer wink and the accept wink, and in a digital packet on the PRI.

I believe you said yours were digital, but it's not sounding like that
now...
