Two-way, loop OAID, TIE trunk call states - incoming call from far-end PBX
When seized as a dial-selected outgoing trunk, the near-end 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.
See Figure 205 "Two-way, loop OAID, TIE trunk call states - outgoing call to
far-end PBX" (page 657) and Figure 206 "Two-way, loop OAID, TIE trunk
call connection sequence - outgoing call to far-end PBX" (page 658) .
