This implements QSIG Network Basic Call.
TTC
For private networking. Requires a Digital Trunk (Japan 2 MB
TTC) (TN2242) circuit pack.
Valid entries Usage
PROGress
Normally select this value. PROGress asks the public network
to cut through the B-channel and let the caller hear tones such
as ringback or busy tone provided over the non-ISDN trunk.
ALERTing
ALERTing causes the public network in many countries to
play ringback tone to the caller. Select this value only if the
DS1 is connected to the public network, and it is determined
that callers hear silence (rather than ringback or busy tone)
when a call incoming over the DS1 interworks to a non-ISDN
trunk.
