Comdial Dsu II Digital Telephone System Instructions Manual

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...

dropped by the caller. The caller continues to receive ringback tone until the call is
answered. The overflow station can service the call or transfer it back to the department
using the department pilot number. When the call is transferred back to the department
by an overflow station, it will not return to the overflow station until that station is idle
and has no ringing calls either new or transferred. Instead, the call will camp-on at the
department and wait for a station to become idle. The caller...

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 wrap-up mode by pressing Hold 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...

Wrap-Up Time: The time that a station spent in a wrap-up mode doing such things as
follow-up paperwork. While a station is in a wrap-up mode, it does not receive
department calls. The station user sets a wrap-up mode by pressingHoldandDNDand
repeats the procedure to clear the wrap-up mode.
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...

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...

Direct Station Call Hold (Station Park)
This feature allows a station user to park a call at a specific station where it will be held
without ringing. A feature code plus a station extension number can be dialed over the
intercom line to park the call or a programmable button can be programmed to provide a
“directed hold” to a specific station. The parked call is picked up by directed station by
dialing a feature code. It can be picked up at any station through the use of the call
pickup feature. No...

Do Not Disturb Inhibit
The system can be programmed to inhibit any station from entering the DND mode.
System class of service programming is used to program this feature.
Do Not Disturb Override
Stations can be provided with DND override capability which will allow them to call a
station that is set in the DND mode. The Executive/Attendant Override feature must also
be active for DND override feature to function. Station class of service programming is
used to assign this feature.
Dual Intercom

Dynamic Line Buttons
Through class of service programming, the programmer can arrange certain idle line
buttons to serve as dynamic line buttons. This feature allows the system to temporarily
assign a line to a station that normally does not have the line assigned to it, and have that
line appear on a dynamic line button. While the call is appearing on the dynamic line
button (LED on), any normal call handling operations can be performed. Station class of
service programming allows certain buttons to be...

Executive/Attendant Override
This feature allows the user of a station, upon encountering a busy signal at another
station, to dial a code that will override the busy signal of a call, sound a warning tone,
and allow access to the existing conversation. This feature is enabled through station
class of service programming.
External Paging Interface
A dedicated paging port or a spare line port can be interfaced with an external paging
amplifier. The paging amplifier can then be dial-accessed by stations in...

Flexible Ringing Assignments Of PA Port
The PA port can be programmed for flexible ringing assignments and zone pages. Any
desired lines can be programmed for direct ring, delay ring, or night transfer (of ringing)
at this port. Paging can be to programmed zone or to all-call. A speaker can be connected
to the PA port to sound the ringing that is generated by the system and sent to this port
and paging announcements when they are sent to the programmed zone. Using such an
arrangement, it is possible for...
