Busy Verification B-3
Service Conditions (cont’d)
14. CALL WAITING [C-12, 31]: If an Attendant attempts to busy-verify a station line that already has a
waiting call, BUSY VERIFICATION will be denied. Also, if the Attendant attempts to busy-verify a
station line that is waiting for another line, the BUSY VERIFICATION attempt will be temporarily
denied, because such waiting calls always involve either a connection to the Attendant position or the
calling party is listening to the ringback tone.
15. UNIFORM CALL DISTRIBUTION (UCD) [U-1]: The Attendant can busy-verify a station line that is
part of a UCD group. That is, the BUSY VERIFICATION call will not hunt. If BUSY VERIFICATION
is attempted on the group number, UCD hunting will take precedence over BUSY VERIFICATION.
16. It is determined in system data to allow monitoring of the busy connection before establishing a three-way
call.
17. The Attendant cannot monitor the call when activating the INDIVIDUAL TRUNK ACCESS [I-4].
18. When the Attendant presses the TALK key and enters a three-party call, the Attendant cannot return to the
monitor mode.
19. While monitoring, only the operations via the TALK key or CANCEL key are valid.
20. If one of the originally connected parties disconnects while the Attendant is monitoring the call, the
reorder tone is sent to the Attendant and the other party. The third party will remain on hold.
21. While being monitored, the switch hook flashed by the originally connected party is invalid.
22. The billing during the monitor mode is continued from the status before monitoring.
23. The node accommodating the Attendant Console requires CFT function for FCCS service.
Interactions
1. This feature is allowed whenever the destination telephone set is engaged in any state other than:
a.) a three-way connection,
b.) a PRIVACY [P-14D, 15D] feature is activated,
c.) connected to a route programmed to have Line/Trunk, Privacy, CDN 44:PRV,
d.) listening to a tone (dial tone, reorder tone, service set tone, busy tone, ringback tone).
2. With the ATTENDANT OVERRIDE [A-7] feature, the following trunk types may be verified busy or idle
status:
a.) one-way incoming trunks,
b.) one-way outgoing trunks,
c.) bothway trunk.
3. Trunks in a station-trunk connection, TRUNK-TO-TRUNK CONNECTION [T-10], and ATTENDANT
CONTROLLED CONFERENCE [A-2] can be verified when busy.
4. ATTENDANT LOCKOUT [A-5]: The Attendant is prevented from verifying a busy station line which is
connected to a loop held at the Attendant Console. Since the LOCKOUT feature applies only to calls held
on an Attendant Console loop, BUSY VERIFICATION of those station lines will be denied and the
Attendant will hear the reorder tone.
5. CALL FORWARDING - ALL CALLS [C-5], BUSY [C-2]: If an Attendant attempts to busy-verify a
(busy or idle) station line that has the CALL FORWARDING (ALL CALLS [C-5], BUSY [C-2]) feature
activated to another station line, the call will be forwarded to the other line, and BUSY VERIFICATION
will proceed as if the Attendant had attempted to busy-verify the other line. If an Attendant attempts to
busy-verify a (busy or idle) station line that has the CALL FORWARDING (ALL CALLS [C-5], BUSY
[C-2]) feature activated to the Attendant, BUSY VERIFICATION will not be denied.
6. CALL HOLD [C-6]: When two stations have established a connection and one of the stations has a third
party on hold, the two talking parties can be busy verified, but the party on hold cannot be busy verified.
