Two-way, loop OAID, TIE trunk call states - outgoing call to far-end PBX

When seized as a dial-selected outgoing trunk, the near-end places the

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 208 "Two-way, loop OAID, tie tr unk call states - outgoing

call to far-end PBX" (page 660) and Figure 209 "Two-way, loop OAID, tie

trunk call connection sequence - outgoing call to far-end PBX" (page 661).
