Two-way, loop OAID, TIE trunk call states - incoming call from far-end PBX
When seized as a dial-selected outgoing trunk, the Universal Trunk places
battery on the tip and ground on the ring. This alerts the far end of the
seizure. The far end responds with a low resistance across the tip and
ring leads.
