Parameters
delay: When using the delay start mode, the calling end occupies the trunk line, and the called end, such
as PBX, will also enter the hook-off state to respond the caller till it is ready for receiving the called
number.
immediate: Immediate start mode. The caller end hooks off to seize the line through line E and sends the
called number. The immediate start mode is applicable when the equipment at the remote end is able to
detect the dial signal immediately after identifying the off-hook signal.
wink: Wink start mode. The caller end hooks off to seize the line through line E, and it has to wait for a
wink signal from the remote end before sending out the called number.
