Comdial Dxp General System Description Release 10a Instructions Manual

Adding Boards Without Renumbering
When you install additional boards or relocate existing boards after the system is in service, the logical
numbers of the stations or lines on the added board continue from the last assigned logical number. For
example, if your last assigned station number was 116, the next station number will be 117, regardless of
the board’s physical slot. This is not true, however, when you remove and delete a board through
programming. After you remove and delete a board through...

Explaining Call Forward Outside System
The Call Forward Outside System (CFOS) feature allows the system to forward incoming or transferred
line calls to telephone numbers that are outside the system. The CFOS feature forwards calls over any
available outbound lines or line groups and does not use any conference circuits. Since CFOS involves
outbound calls, those calls are subject to all line access, toll restriction, and automatic route selection
restrictions normally imposed on the users. Any calls that...

In summary, to fully enable CFOS for use, programmers must take the following programming actions:
– enable CFOS with system programming,
– enable CFOS in station class of service,
– assign the CFOS class of service to the CFOS stations,
– enable CFOS in individual station programming,
– map a CFOS button on non-LCD telephones,
– select a destination number while mapping the CFOS button,
(this is an optional step—any user selection overrides this selection),
– enable lines for CFOS capability,
–...

Supporting the E1 Line Board
Beginning with software release 10A, the DXP supports the use of the DXPE1–nnn line board for
international applications. The E1 board provides 30 channels of voice transmissions over a single,
four-wire, 120 ohm cable or over two 75 ohm coaxial cables using multiplexing techniques. The DXP
accepts up to six DXPE1–nnn line boards in specified board slot locations—three in the main cabinet and
three in the expansion cabinet.
Different nations require different system...

Understanding Station Hunting
Station hunting is available to systems with a software revision of 10A and later. Station hunting provides
a means of routing both intercom and outside calls through an installer-determined grouping of stations.
This call routing continues to a designated overflow location in case of no answer or if all stations in the
hunt group are busy. Station hunting works equally well with intercom, standard central office (CO)
lines, direct inward dialing (DID/DNIS) lines, direct...

Hunt Group Attributes
Pilot Extension: This is the extension number that callers dial to call or route calls to this hunt group.
The pilot extension number is similar to a personal intercom number, or extension number, and follows
the same numbering plan restrictions. When station hunting is used with DID/DNIS, the pilot extension is
the extension number assigned in the DID/DNIS translation table. When station hunting is used with
DISA, the pilot extension can be the extension number assigned to the...

Types Of Hunting
Terminal Hunting:Terminal station hunting always delivers a call to the first idle station programmed
in the hunt group. If the station does not answer within a programmed amount of time (programmed as
the Call Advance Timer), the system delivers the call to the next sequential idle station programmed in
the hunt group. The system makes no attempt to balance the distribution of incoming calls as this is a
linear search through the programmed list. The search starts at the beginning of...

Station Hunting Timers
Call Advance Timer: This is the time interval that a station within a hunt group rings unanswered before
the system routes the call to the next station in the group. This timer is programmable from 10 seconds
though 5 minutes.
Overflow Timer: This is the maximum time interval that an unanswered call hunts within a group before
the system routes it to the designated overflow station for the group. This timer is programmable from 30
seconds through 15 minutes.
Recall Timer:This is...

Introducing the Visual Man-Machine Interface
The Visual Man-Machine Interface (VMMI) is menu-driven programming software for the DXP digital
communications system. The VMMI software allows the programmer to enter choices in dialog boxes
and accept the entries as valid. The VMMI program includes a detailed, context-sensitive, on-line help
file that the programmer can reference at any time during the programming sequence. The software is
accompanied by GCA40–182,Understanding The VMMI,which details...
