Start Signal
y
Immediate Start
The originating end seizes the line by going off hook and, without waiting
for a response, it begins to outpulse digits. The address signaling used with
immediate-start signaling Consists only of dial-pulsing.
y
wink-Start
The originating end seizes the line by going off-hook. It waits for
acknowledgement from the other end before outpulsing digits. This serves
as an integrity check that will identify a malfunctioning trunk and allow the
network to send a re-order tone to the calling party.
y
Delay Dial
The originating end seizes the line and waits 200 ms to see if the far end is
on-hook. If so, the originating end then outpulses digits. If the far end is
off-hook, the originating end waits until the far end is on-hook before
outpulsing digits.
Restrictions of DID Trunk
