Values: n = 0, 1, 2, or 3
Default: 0
Description: Controls the V.92 shortened Phase 1 and Phase 2 startup procedures (quick connect).
When line conditions are stable, quick connect results in shortened connect times;
however, significant fluctuation in line conditions from call to call can result in longer con-
nect times, in which case it may be advisable to disable quick connect. The +PQC com-
mand is interactive with S109.
