Eight-bit value returning the loop current. Each bit represents 1.1 mA of loop current.
0000_0000 = Loop current is less than required for normal operation.
Line Voltage Status.
Eight-bit value returning the loop voltage. Each bit represents 1 V of loop voltage. This regis-
ter operates in on- and off-hook modes. Bit seven of this register indicates the polarity of the
TIP/RING voltage. When this bit changes state, it indicates that a polarity reversal has
occurred. The value returned is represented in 2s complement format.
0000_0000 = No line is connected.
