566 NT8D14 Universal Trunk card
Figure 182
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) .
