Direct Department Calling With Departmental Call
Distribution (DCD) - continued
Missed Calls: The total number of calls that are not
answered at a station and that are cycled by the
system to another station for answering.
Other Calls: This is a summation of the time spent
on outgoing call activity, incoming call activity on
non-department lines, plus all intercom call activity.
On-Duty Time: The on-duty time includes a
summation of idle time, department call time,
wrap-up time, and other call time.
Off-Duty Time: The time that a station spent in a do
not disturb mode. While in a do-not-disturb
condition, a station is not available to receive calls.
The station user sets a do-not-disturb mode by
pressing DND and repeats the procedure to clear
the do not disturb mode.
Unanswered Calls: Total number of calls that went
unanswered at a department.
Calls Answered After 36 Seconds: Total number
of calls that waited at least 36 seconds
(approximately six rings from the CO) before being

Calls Handled By Overflow Station: Total number
of calls that were answered and transferred by the
overflow station and then answered and serviced by
another station.
Calls Terminated At Overflow Station: Total
number of calls that were received by the overflow

transferred or were dropped by the caller before
being answered.
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 it 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, it is a good practice to
set it 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 system 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 thecalled 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 forward feature
set, the forwarded station rings. If a called station is
busy, the call is placed on hold and camped-on at the
busy station. If the camp-on 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: If the busy called station is part of a hunt
group, the DISD call is routed to an idle station in the
hunt group. If no idle stations are found, the call is
camped-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 #+ 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
to the DISD assist station if one is programmed;
otherwise, the line is dropped. If the assist station is
busy (call will camp-on at the assist station) or if the
assist station does not answer before the transfer
recall timeout period, the system will return the caller
to DISD dial tone. If extension number dialing is not
completed within the dial time limit this time, the line is
dropped.
The installer should connect a music source to the
system so the music can provide a reassurance to the
caller during a camp-on situation when the DISD
feature is being used.
