V
Programs the voltage delta below the VOC value at which the VOCDELTA offset voltage
is added. This threshold is only applicable during the on-hook to off-hook transition, and
the VOCTHDH RAM location determines the threshold voltage during the off-hook to
on-hook transition. Default value is –8 V. 0 to 63.3 V range, 4.907 mV/LSB, 1.005 V
effective resolution.
Overhead Voltage.
Programs the overhead voltage between the RING lead and the voltage on the VBAT
pin in normal polarity (between TIP and ground in reverse polarity). This value increases
or decreases as the battery voltage changes to maintain a constant open circuit voltage,
but maintains its user-defined setting to ensure sufficient overhead for audio transmis-
sion when the battery voltage decreases. 0 to 63.3 V programmable range, 4.907 mV/
LSB, 1.005 V effective resolution.
Reflects the TIP-RING voltage during on-hook conditions when the battery supply has
dropped below the point where the VOC setting cannot be maintained. 0 to 63.3 V pro-
grammable range, 4.907 mV/LSB, 1.005 V effective resolution.
