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 189 "Two-way, loop OAID, TIE trunk call states - outgoing call

to far-end PBX" (page 573) and Figure 190 "Two-way, loop OAID, TIE

trunk call connection sequence - outgoing call to far-end PBX" (page 574).
