DXP Plus Programming
15.1 Understanding The Board Configuration Feature
Because there are no dedicated station or line ports in the plus, the system uses an automatic configuration
method to logically number its stations and lines. Automatic configuration occurs after you perform a master clear
on the system.

With automatic configuration, the system does a search for all installed station and line boards
in the main and expansion cabinets, and assigns a logical number for each provided station and
line encountered during the search. The search begins in the main cabinet at the left-most
universal slot and proceeds left to right. The search then moves to the upper expansion cabinet
where it searches left-most slot to right-most slot. The search finally moves to the lower
expansion cabinet where it again searches left-most slot to right-most slot. When automatic
configuration is finished, the system has logically numbered all station and line ports in
ascending order from the left-most slot to right-most slot throughout the entire system.
The logical number of a station or line corresponds to its relationship to other stations or lines in
the system but is not dependent upon the board’s placement in the cabinet. The physical
location of a station or line corresponds to the order of the system’s board slots. The main
cabinet contains slots l-9, the upper expansion cabinet contains slots 10-20, and the lower
expansion cabinet contains slots 21-30. Therefore, even if the first encountered station board is
located in slot five of the main cabinet, the system still assigns logical number one to the first
station provided by that board. During installation, you can skip slots. For example, you can
install eight-line, loop start, line boards in only slots one and 30 if you wish. In this case, slot
one yields logical line numbers 1-8 and slot 30 yields logical line numbers 9-17.
Each installed board requires timing circuits equal to its capacity. For example, a
board requires 16 timing circuits, an eight-line loop start line board requires eight circuits, and a
fully configured trunk board requires 24 timing circuits. In the
plus,
each universal slot
provides 32 timing circuits. Because of this timing circuit provision of each slot, you can place
any station or line board at any slot location with no restrictions.
If you install or relocate a station or line board, this board does not operate until you take
appropriate programming action described in Sections
15.4,
or 15.5.
If you use an
available open slot for adding or relocating a board, that board’s stations or lines assume logical
numbers in sequence after the system’s last assigned logical station or line number. For
example, if the system’s last logical station number is 24, the logical numbers of the newly
installed board’s stations begin at logical number 25.
After you remove a board and delete it through programming, that boards’s logical numbers are
available for reassignment. This means that you can remove a board, add or move another
board, take the appropriate programming action, and have the stations or lines of the added or
relocated board assume the logical numbers made available by the removed board. For example,
if the system’s last logical number is 64 and you remove the board providing stations with
logical numbers 1-16, the stations provided by an added board assume logical numbers
beginning with 1 instead of 65. However, if you remove an eight-station board and add a
board, the first eight stations stations on the added board assume logical numbers
and the last eight stations assume logical numbers 65-72.
Remember, should you master clear the system, the automatic configuration feature logically
numbers all station and line ports in ascending order from the left-most slot to right-most
slot
throughout the entire system. This action renumbers those station and lines provided by boards
that you have added or relocated since you last performed the system master clear.
