Operation Description
Station alerting When a call is offered to a station, an inter-PN connection is
initiated and the phone rings. This procedure applies to
calls to stations, data modules, and attendant consoles.
When the user answers, the station should be connected
before the user says “hello.”
Trunk seizure Trunk seizure happens after an outgoing call is submitted
to an outgoing trunk port, followed by address outpulsing.
Seizure and address outpulsing do not require an
established talk path to the trunk. If the talk path to or from
the trunk is delayed for several seconds and the call was
dialed instantly through abbreviated dialing, some initial
call progress feedback might be missed and, perhaps,
some information from the answering party.
Connection setup times of as much as 1-2 s can be
covered by seizure/outpulsing, but longer setup times
require postponing seizure until the inter-PN connection is
established.
Recorded announcements When an announcement is connected, it requests playback
as soon as possible. The switch delays playing back an
announcement until at least one inter-port-network
connection, if needed, is established.
The barge-in announcements, which the caller joins in
progress, do not require this delay.
