DTMF Receiver Tests
(Main Cabinet, Expansion II Cabinet, and Expansion III Cabinet)
This diagnostic test checks the functionality of the DTMF receivers located in the cabinet under test. The test
performs its check by connecting DTMF tones 0-9,
✳
, and # through the timeswitch and confirming that the
correct tone was recognized by the receiver.
The system displays the number of each tested DTMF receiver in the cabinet along with a message that tells
whether the receiver passed or failed the test. While the actual displayed numbers for the DTMF receivers vary
depending upon how many receiver cards that you have installed in the system, the displayed numbers for each
cabinet reflect DTMF receiver locations in that cabinet. These locations begin with the receiver card located in the
upper slot on the leftmost host board, proceed to the lower card slot on that host board, and then progress to the
upper card slot on the next host board to the right of the first.
You can install receiver cards in any of the locations shown in the following chart.
Receiver Card Location
Main Cabinet Auxiliary Board
Services Board (see note)
Upper Expansion Cabinet Interface Board
Upper Expansion Cabinet Auxiliary Board 1
Upper Expansion Cabinet Auxiliary Board 2
Lower Expansion Cabinet Interface Board (see note)
Lower Expansion Cabinet Auxiliary Board 1
Lower Expansion Cabinet Auxiliary Board 2
CPU Board (no receiver card required)
NOTE: If you place two receiver cards in the lower two
positions of the Services board, you must take specific
programming action (Services DTMF Highway) to
enable their use. If you do this, you can add only one
reveiver card to the Lower Expansion Cabinet Interface
board.

Speaker Coefficients
Certain models of Comdial digital telephones have performance characteristics that can be modified by using this
section of diagnostics. Do not attempt to modify any of the values found in this section unless you have been
directed to do so by a Comdial technician; doing so could severely impact the performance of the associated
telephone. Once modified, these values remain in the telephone’s permanent memory and are not affected by a
master clear.
