Parity is a number derived automatically by the dialer utilizing a mathematical formula (modulo
15). E.g., 123 3 adds up to 9. This is subtracted from the next highest multiple of 15; in this case,
15 - 9 = 6. If the CS receiver accepts a valid parity digit, it considers the data transmission valid,
delivers a "Kissoff" and processes the data. The parity digit is not displayed. Its only purpose is
for validation of data transmitted. It is not a programmable digit; it is generated automatically by
the dialer when the parity option is selected in Programming Question 15, L2/L4. The obvious
advantage of using parity is speed. The transmission time between dialer and receiver is shorter
because fewer digits are transmitted with it as opposed to without it.
