Further, the system camp-on feature cannot be used to camp-on to a department.

Subsequent calls to a department on a particular line always try the next station in the department from whichever station serviced the last call on that line. This means that if department stations 15 and 16 are programmed to answer line 1, and station 15 services a call, the next line 1 call will ring at station 16. When both stations 15 and 16 are programmed to answer lines 1, 2 and 3, call delivery is on a per line basis: If station 15 handles and completes calls on line 2 and 3 while station 16 is still on line 1, the next calls on line 2 or 3 goes to station 15 even if station 16 has become idle.

Since the RNA time of a station is a programmable feature, department stations can be set to have a short RNA time to allow a call to search rapidly through a department for an answer.

When an outside or transferred call is ringing at a department station, the station user can press the pre-programmed Do Not Disturb (DND) button to place the station in an off-duty condition. While off-duty, all outside and transferred calls skip to the next department station. This offduty condition remains set until the DND button is pressed again to place the station back in service. When the overflow station is set to DND, all incoming and transferred calls will return to the department queue.

A department station can also be taken out of service and placed in a wrap-up mode to provide the user time for doing such things as follow-up paperwork. While a station is in a wrap-up mode, all outside and transferred calls skip to the next department station. The station user sets the wrapup mode by pressing SHIFT DND and presses these buttons again to clear the wrap-up mode.

It should be noted that the departments formed for use with this direct department calling feature are different from those departments used in SMDA reporting.

Assign department transfer recall time (unanswered call transfer recall time feature) using the system class of service programming. Assign lines for direct department calling using the line class of service programming. Assign department stations, access codes to departments (flexible numbering feature), and busy/RNA timeout (call forward - busy feature) using the station class of service programming. Also refer to the discussion titled: Departmental Calling Distribution Report.

DIRECT INWARD STATION DIALING (DISD)

The DISD feature allows an external party to call an intercom station directly without assistance by the attendant. The DISD call must be received on a line which has been specially programmed to allow this feature. Any line can be programmed to be a DISD line for both the normal mode of operation and the night transfer (of ringing) mode of operation.

The number of rings which occurs on a DISD line before tt is answered is programmable. By setting a large number of rings, time is allowed for a call to be serviced in a regular manner by stations that have a line appearance for the DISD line. Setting the number of rings to 0 disables the line for DISD use. If a line is to be dedicated for DISD use, tt is a good practice to set ft for one ring. The amount of time allowed for an extension number to be dialed is programmable and a DISD assist station can be programmed to answer calls that are not completed during this dial time limit. When a DISD line is called, it rings for a programmed number of rings. If the call is not answered in a normal manner by a station with the line appearance during this time, the system answers it and presents a DISD dial tone to the caller. The s;:stem then waits for an extension number to be dialed from the calling telephone. Only one DISD line is serviced at a time; therefore, an incoming call could ring for more than the programmed number of rings if a DISD call is being serviced when a second DISD call is received.

When a valid extension number is dialed, a confirmation tone is sounded, the system attempts a transfer, and the called station rings if it is idle. If a called station does not answer within the transfer recall timeout period, the call is returned to DISD dial tone. If the called station has the call fonnrard feature set, the forwarded station rings. lf a called station is busy, the call is placed on hold and camped-on at the busy station. ff the camp-cm is not answered within the transfer recall timeout period, a busy tone is given followed by DISD dial tone. The system will return the caller to DISD dial tone two additional times and then drop the line (a total of three attempts are made).

NOTE:lf the busy called station is part of a hunt group, the DISD call is muted to an idle station in the hunt group. lf no idle stations are found, the call is catqoed-on at the dialed station. The hunt group is not followed in the case of a ring-no-answer (RNA).

If an invalid extension number is dialed, an error tone is sounded before the DISD dial tone is returned. If a mistake in dialing is made, the caller can dial a S for a new DISD dial tone. The system will return the caller to DISD dial tone two additional times and then drop the line. If extension number dialing is not completed within the programmed dial time limit, the call is routed
