DuSLICOS allows to automatically calculate the coefficients for K
measurement. The expected "Current for Ring Off-hook Detection" (see DuSLICOS DC
Control Parameter 2/3) of e.g. 20 mA is entered in to the program and then K
automatically calculated to achieve 50 % full scale if the current of 20 mA is integrated
over the set ringer period.
The integration function accumulates and sums up the levelmeter values over a set time
period. The time period is determined by the programmed ring frequency. A ring

RGF1, RGF2 and RGF3 are 4 bit nibbles which control the ring frequency f
RGA1 is a 4 bit nibble which is calculated by DuSLICOS and controls the ringer
amplitude (see DuSLICOS byte file). To ensure that RGA1 is not changed please
perform a read/modify/write operation.
