The basic system consists of a main cabinet, which accepts 14 printed-wire boards, and two expansion cabinets; the upper expansion cabinet accepts twelve printed-wire boards, and the lower cabinet accepts eleven (see Figure 7). Some of the printed-wire boards also hold smaller circuit cards that mount directly to the boards (See section 3.5 for card information) The line boards are listed in section 3.3; station boards are located in section 3.4. The complement of circuit boards include the following (for information on the main Comdial FX, FXT, FXS, MP5000 package, see section 3.6, Locating The Boards):
Auxiliary Board: — A utility board that provides interface for a maximum of four special-purpose circuit cards. Actual make-up requirements depend upon system configuration.
Central Processing Unit (CPU) Board: — Provides central processing and control for the system and other miscellaneous functions. The CPU board has the time switch and conference circuitry and two serial data ports, which have been dedicated for PC-based programming and a remote maintenance modem.
Conference Board: — Provide additional conference capability. Each board provides 5 additional 3-way conferences.
Interface Boards: — Ties the main cabinet to the expansion cabinet. Each expansion cabinet has an interface board; that connects the main cabinet with the expansion cabinets. Interface boards are included with the expansion cabinet packages.
Memory Card: — Provides the memory storage and operating system control. The card mounts directly onto the CPU board, and it is available with two (four megabyte as a future feature) of memory. The system uses re-programmable random access memory, known as “flash memory” or “flash RAM” —not replaceable memory chips, known as “EPROM”.
Services Board: — Provides an interface for music-on-hold and background music inputs; it also provides an output to an external paging amplifier. The services board includes four dry-contact relays for external control functions. You can also add up to three additional cards onto the services board for data communications, DTMF tone receiving, and E1 or T1 synchronization.

Because there are no dedicated station or line ports in the DXP Plus, 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 cabinets. Once the system has identified the board type and location, it automatically numbers the ports on every installed board (see the section below, “How the system renumbers logical ports,” for more information on renumbering). Comdial DXP Plus
H o w t h e s y s t e m renumbers l o g i c a l p o r t s
The automatic renumbering configuration, which renumbers the logical ports, 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 upper expansion cabinet and continues searching from left to right. Finally, the system searches the lower expansion cabinet, again 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 each cabinet throughout the system.
A d d i n g b o a r d s without renumbering Comdial DXP Plus
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 16, the next station number will be 17, regardless of the board’s physical slot.
After you remove and delete a board through programming, that board’s logical ports are available for reassignment. So an added or relocated board would then take the logical port numbers from the removed board and not from the end of the logical sequence. For example, if you had 64 stations and were to remove a station board that had held logical stations 1–16, the next station board that you installed would occupy logical station ports 1–16 and not ports 64–80. If you were to remove an 8-port board and replace it with a 16-port board, the first eight ports on the new board would replace the original eight logical port numbers, and the remaining eight ports would begin with the last assigned logical port. So using our same scenario, the new 16-port board would have logical ports 1–8 and 64–72.
