4. A DISD line recalls to the DSU after a transfer recall time, and the DVA plays a
recall message to the caller. The DSU transfers the call once more to the same or
different stations. This action repeats three times.
5. After the last recall, the DVA plays the drop message and the DSU drops the line.
The installer can connect DVA devices to any available digital station ports. The
availability of station ports limits the number of DVA devices that can be connected to
the system. The system programmer arranges the DSU class of service programming to
customize the DVA operation for specific applications.

Direct Department Calling With Departmental Call Distribution
The system enhances direct department calling with departmental call distribution (DCD)
and provides a means by which outside lines can be assigned to one of four different
departments. Calls received on department lines and calls that are transferred to a
department from within the system search for an idle station in that department. The
system distributes department calls evenly throughout the department stations for
answering with individual stations having the ability to be taken out of service as
necessary. The system places calls received on department lines and calls that are
transferred to a department from within the system in a queue for servicing. It assigns
new calls, transferred calls, and held calls a time stamp so that they will be serviced in
the order of their arrival.
The system allows up to four departments and allows up to 16 stations and a minimum of
3 stations (plus one overflow station) in each one. The programmer can assign a station
to more than one department, if desired. Since the programmer can assign a station to
more than one department, she or he can add the attendant station to serve as the
overflow station for all departments if desired. The programmer can assign separate pilot
numbers (extension numbers) to each department that the users can use for making
intercom calls or doing call transfers to the department.
The direct department calling feature requires that the programmer assign lines and
stations to a department. It does not require that he or she assign department lines to
appear at buttons on department stations. If a site requires that a particular department
line must appear at a particular department station, the programmer can assign it;
however, the programmer must ensure that neither direct nor delayed ringing is enabled
for that line at that station.
An incoming call searches for the first station available to answer a call. If all stations in
a department are busy or ring with no answer (RNA call), the call will go to the overflow
station in that department (if one has been programmed). If there is no overflow station
programmed, the call continues to try the department stations until it is answered or
