UNIFORM CALL DISTRIBUTION (UCD) (CONT’D)
SERVICE CONDITIONS (CONT’D)
17. The maximum number of queuing in each UCD group (hereinafter called Queue Size) can be specified
by the system data. When the number of queuing calls reaches the preassigned queue size, new calls
receive Busy Tone or prerecorded OVERFLOW ANNOUNCEMENT - UCD. Depending on the
queue size, the call waiting lamp indication on D
term
or the external equipment indication is provided
as shown below:
Queue Size assigned by system data = n
Number of queuing calls = N
Note: The external indicator is available for Australia only.
18. An incoming Listed Directory Number (LDN) received from DIRECT - INWARD DIALING (DID)
line can be displayed on the LCD of a D
term
station in the UCD group. The system data is assigned on
trunk route basis.
19. The DID incoming LDN display is one digit to four digits.
20. When digit conversation of DID incoming LDN has been activated, number before conversion which
received from C.O. is displayed.
21. A DID incoming LDN is converted to a UCD station number, by analyzing the upper two-four digits of
DID incoming LDN. A maximum of 10,000 DID incoming LDN can be converted to a maximum to
500 UCD station numbers.
22. Priority Queuing is available for incoming trunk calls. The queue priorities are assigned on a trunk
route basis or per station number on DID call.
23. When a call has terminated to UCD group A, and all stations in group A are busy, and group B is
assigned as the overflow destination (using CALL FORWARDING - BUSY LINE), the call is trans-
ferred to group B. When all the stations are busy in group B, the call queues onto UCD group A.
24. One overflow group can be provided for each UCD group. Overflow to another group is accomplished
by using CALL FORWARDING - BUSY LINE at the pilot station of the first UCD group.
25. Refer to the following features for more information:
• AGENT BUSY OUT - UCD
• DELAY ANNOUNCEMENT - UCD
• OVERFLOW - UCD
• OVERFLOW ANNOUNCEMENT - UCD.
