Open Circuit Voltage.
Programs the TIP-RING voltage during on-hook conditions. The recommended value is
48 V but can be programmed between 0 and 63.3 V. 4.907 mV/LSB, 1.005 V effective
resolution.
V
Programs the voltage delta above the VOC value at which the VOCDELTA offset volt-
age is removed. This threshold is only applicable during the off-hook to on-hook transi-
tion, and the VOCTHDL RAM location determines the threshold voltage during the on-
hook to off-hook transition. Default value is 2 V. 0 to 63.3 V range, 4.907 mV/LSB,
1.005 V effective resolution.
Programs the amount of offset that is added to the VOC RAM value when the device
transitions to off-hook. The recommended value is 7 V. 0 to 63.3 V range, 4.907 mV/
LSB, 1.005 V effective resolution.
