Two-way, loop DR, TIE trunk call states - incoming call through senderized, tandem PBX from
a CO/FX/WATS trunk

Note:

If a ground start trunk, the outpulse towards the office occurs

after ground detection. If a loop start trunk, the outpulse toward the
office occurs one second later.

For immediate start, following the seizure signal, the far-end may start
pulsing after the standard delay (normally 65 ms, minimum).
