Table D-4. Summary of Vector Events

Event	Event	Event
Type	Description	Explanation
11	No announcement available	During an announcement step, a collect
		digits step that contains an
		announcement, or a disconnect step, the
		announcement was not available for one
		of the following reasons:
		■ Announcement was not recorded
		■ Analog announcement was busied out
		■ Integrated announcement board was
		not installed
		■ Integrated announcement ports were
		busied out
		■ Integrated announcement was being
		recorded or restored
20	Call cannot be queued	A queue-to main split, messaging split, or
		check-backup split command failed to
		queue the call.
		NOTE: Event types 520, 521, 522 and 541
		may be observed for the same call at the
		same time.
21	Queued to three splits	The call attempted to queue to four
		splits. Multiple split queuing allows the
		call to queue to a maximum of three splits
		simultaneously. If the call queued to one
		or more splits, and if it should now be
		dequeued from those splits and then
		queued elsewhere, one solution is to route
		the call to a station (which may be
		administered without hardware). Once
		this happens, the call is forwarded to the
		VDN that controls the next stage of the
		call.
30	No TTR available	A collect digits command failed because
		■ TN744 port was not available
		■ All queue slots were occupied
31	Dial-ahead discarded	Previously entered dial-ahead digits have
		been discarded via access of a(n) adjunct
		routing, converse-on, route-to number, or
		messaging split step.
