							Introducing Software Release
10A
Software release 10A for DXP contains a unique group of features that enhance system operation in a
variety of ways. Software 10A does not replace software 9 as this earlier software release still provides a
full compliment of existing features for those who do not want or need the unique features that are a part
of the 10A release.
Software release 10A provides the following system enhancing features:
·Board Configuration (new logical to physical relationship and additional T1/E1 slots)
·Call Forward Outside System (CFOS)
·E1 Line Board Support (for international applications)
·Station Hunting
·Visual Man-Machine Interface (VMMI) programming
Understanding The Considerations For 10A Software
Understanding The 10A Hardware Considerations
·The DXP system must be operating on a DXCPU–68K CPU board. The 10A software release is not
compatible with systems using a DXCPU–186 CPU board found in earlier produced DXP systems.
·The board configuration feature requires new cabinet labeling. (The 10A software package includes
new labels.)
·The T1/E1 circuit board can occupy new locations in addition to those allowed in previous software
releases.
·The 10A software release requires a new Random Access Memory (RAM) card (product code
DXRAM–EXPC.) that you must install as part of the software up-grade.

							Understanding The 10A Software Considerations
·The PCMMI (off-line) and embedded MMI (on-line) programming procedures are no longer
available with 10A software; however, a new windows-based Visual Man-Machine Interface
(VMMI) on-line programming technique, complete with exhaustive help files, is available to replace
it.
·The DXP databasemustbe at least revision 9A before you can up-grade it to 10A. (You can use the
9A revision of the PCMMI programming software to up-load your current DXP database and then
down-load it to a data storage area such as your computer’s hard drive as a revision 9A database.*).
You must then use the new VMMI feature to translate this stored 9A database into a 10A database
before you load it back into the DXP.
·The PC Attendant Position software must be at least revision 5A. (Youmustup-grade the software
in your PC Attendant to this level to be compatible with the 10A software release.*) It is a good
practice to up-grade the PC Attendant Position computer to contain at least 2 megabytes of RAM
memory. While this may not be necessary for every installation, up-grading to 2 megabytes of RAM
memory ensures that the PC Attendant Position functions properly under all conditions.
* Remember, you can always down load the latest PCMMI, VMMI, and PC Attendant software from the Comdial Technical Services Bulletin
Board by calling 1–804–978–2583 or from the Comdial home page on the World Wide Web by connecting at: http://www.comdial.com/ .

							Understanding The Board Configuration Feature
Defining The Physical And Logical Board Locations
Beginning at software release 10A, theDXPuses two distinctions for station and line locations: the
physical location and the logical location.
Thephysical locationcorresponds to the order of the board slots in the system; these physical slot
locations never change. There are 16 possible physical slot locations in the DXP (nine slots in the main
cabinet and seven slots in the expansion cabinet) that permit the DXP system to provide a maximum of
128 lines or 192 station ports,
·The right-most four slots (slots 6 through 9) in the main cabinet are reserved exclusively for line
boards.
·Slots 1 and 2 in the main cabinet are the only slots that accept auxiliary boards; however, these slots
will also accept line or station boards.
·All universal slots in both the main and expansion cabinets will accept either line or station boards.
·Slots 3, 5, and 8 in the main cabinet and slots 12, 14, and 16 in the expansion cabinet are the
specified slots for T1/E1 boards. While software release 10A still limits T1/E1 boards to specified
locations, it permits you to use more of them and liberalizes the adjacent slot installation
considerations that you must make:
·There are fewer limitations for placing other line board types in universal slots adjacent to the
T1/E1 board slots. By reducing the limitations on line board placement from earlier software
requirements, the system makes room for the installation of additional station boards thus
increasing the amount of stations a system can support when it has T1/E1 boards installed.
·There are some limitations for board placement in universal slots 2, 4, 11, 13, and 16 when a
T1/E1 board occupies slot 3, 5, 12, 14, and 16.

board occupies slot 8.

							No matter what type of board you install in the first universal slot in the main cabinet, that slot is always
physical slot 1. The physical slot numbers begin with the first universal slot in the main cabinet and
number from left to right. The first universal slot in the expansion cabinet is physical slot number 10.
Installers need to know the physical location of the boards in order to properly wire the lines and stations.
NOTE: The left to right order for the four exclusive line board slots (slots 6 through 9) in the
main cabinet are reversed from the order that they occupied with software revisions
prior to release 10A.
Thelogical locationof a station or a line corresponds to its relationship to the other stations or lines in the
system and is not dependent upon the board’s location in the cabinet. Therefore, if you have installed your
first station board into slot five of the main cabinet, for example, the system still refers to the first station
on that board as logical station one (station one always defaults with intercom 101).
CAUTION
This logical location is a major departure from the way the system operated prior to software release 10A.

							Describing How Automatic Configuration Works
Beginning with software release 10A, there are no dedicated station or line ports in theDXP,the system
uses an automatic configuration method to number the lines and stations. When you master clear the
system, it automatically searches for all installed line and station boards in the main and expansion
cabinet, identifies each board type and location, and automatically numbers the ports on every installed
board (see the next section,Understanding How The System Renumbers Logical Ports, for more
information on renumbering).
Understanding How The System Renumbers Logical Ports
The automatic renumbering configuration, which renumbers thelogicalports, begins at the left-most
universal slot in the main cabinet and proceeds left to right. When the system has configured all of the
boards in the main cabinet, it moves to the expansion cabinet and continues searching from left to right
until it has numbered all of the lines and stations. When the configuration is finished, the line and station
ports are numbered logically from left to right in both cabinets. Remember, this automatically happens as
a result of a master clear operation.
