Considerations for Configuring Trunk-In Signaling
Trunk-in signaling (also referred to as dial in supervision) determines a channel's response to
an incoming call. Keep the following in mind when configuring dial in supervision:
When the far end seizes a channel, there are two possible responses:
l
Immediate — The system seizes back 100 ms after incoming line seizure. This is the
l
default setting. Or, if configured, the system starts DNIS collection.
Winkstart — The system winks back to the far end upon incoming line seizure. This
l
setting applies exclusively to trunks using E&M signaling.
Upon an incoming A/B bit transition, the system always waits for a period equal to the
l
configured Pre-Wink Delay plus 50 ms before taking any action. This ensures that the
incoming seizure is a true seizure, and not a spurious A/B bit transition.
If any of your trunks use E&M signaling, consult the installation's network provider to
l
determine the proper dial in supervision for the channels on those trunks.
You can specify different dial in and dial out supervisions for a particular channel.
