Outgoing calls

When DDL or WNK mode is used, outgoing calls require a stop/go signal

from the far-end so that the near-end cannot outpulse until the far-end is

ready to receive digits. See Figure 177 "Two-way, loop DR, TIE trunk call

states - outgoing call through far-end PBX to CO/FX/WATS" (page 560).

Note:

Pseudo-answer supervision is provided by near-end at expiration

of end-of-dial timer. Where no far-end answer supervision is provided,

the party at the far-end hangs up after recognizing near-end call

termination.
