Table B-1. Switch operability interactions
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.
