Comdial Dsu II Digital Telephone System Instructions Manual

Response Messaging
This feature allows a user to reply in a non-verbal manner to a voice announce or
tone-signaled intercom call or to a subdued off-hook voice announce call if the intercom
caller is using an LCD speakerphone. A station user can press a programmable button in
response to an intercom call and send a message to be shown on the display of the calling
station. Response messages are pre-programmed by the attendant and later stored by
station users at programmable buttons on their individual...

of an external paging amplifier and the installer can arrange the wiring so that the relay
closures energize the paging amplifier while it is receiving the ringing tone. Use system
class of service programming to choose either the paging port. or station port 17 for the
ringing port relay control. Also use system class of service to determine the type of
ringing sent to the paging port. Use station class of service programming to determines
the type of ringing that the system sends to station port 17....

and paging announcements when they are sent to the programmed zone. Using such an
arrangement, it is possible for a user to determine that certain lines are ringing, such as in
a night transfer (of ringing) mode, and go to the nearest telephone and answer the call.
The most common use for this arrangement is as a night bell eliminating the need for
external equipment as required with the common ringer and auxiliary ringer interface.
The speaker cannot be used for voice response as the path is one-way...

Ringing Line Preference
The system can be programmed on a per station basis to provide ringing line preference
on all lines programmed for ringing at the station. When ringing line preference is
enabled at a station, taking the handset off-hook automatically connects the station to any
outside line that is ringing at it. A line button will not have to be pressed. With ringing
line preference enabled, the telephones denote a ringing line with an orange colored
status light. If a station also has prime...

within the same general area. If all nine channels are in use and a tenth Scout telephone
tries to place a call, the LCD will indicate “System Busy” and deny the call. If you do
install more than one  Scout wireless telephone, Comdial recommends that you leave at
least 10 feet between adjacent base units. The range of each Scout telephone is affected
by the layout and location of the base unit, so it is a good idea to install the base unit in
an unimpeded area and at desk-level or higher.
The Scout...

a line group after comparing the dialed number with entries that are contained in an
office code table, an area code table, and four special area code look-up tables.
The specialized route access operates in the following manner: When the caller presses
INTERCOM and dials 9 or presses a preprogrammed button, the system returns a special
dial tone. The caller then has 10 seconds in which to dial some digits; otherwise, the
telephone will return to its idle state. Once a caller begins to dial digits, he or...

The following information illustrates the digit evaluation scheme.

The example below shows how calls to area code 202 are routed using line group 2, calls
to office code 202 are routed using line group 1, calls to office code 973 in area code 716
are routed using line group 4, and all other...

that the CENTREX extensions are 3300–3399. Take programming action to assign line
group 2 to entries 330–339 in the office code table. This means that calls on CENTREX
extensions will use line group 2 and all other calls will default to use line group 1.
Program the 9 digit as the insertion digit for line group 1. With this set up, when a caller
dials a number other than a CENTREX extension, the system automatically inserts a 9
ahead of the dialed digits and routes the call over line group 1.
If no lines...

Flexible Station Numbering Plan
The system supports a flexible station numbering plan for individual stations. Each
station can be programmed to respond to the dialing of any available number between 10
and 7999. This feature may be used to match the calling number of a station located in a
pre-numbered area to that area number. A combination of two, three, or four digit
extension numbers can be assigned as long as they do not conflict. For example: If 21 is
assigned as an extension number, there can not...

Station-To-Station Messaging
If a station has a DSS/BLF appearance at another station, a callback message indication
can be left at that station with the DSS/BLF appearance. The user can dial a special code
to turn on the BLF light at the called station that is assigned to the calling station. This
light indicates that a callback is requested. The light is automatically turned off if a
successful callback is made.
If a station number is not programmed for a DSS/BLF appearance at another station,...
