Line Voltage Current Sense.
Represents either the line voltage, loop current, or on-hook line monitor.
On-Hook Voltage Monitor (2.75 V/bit ±20%)
00000 = No line connected.
00001 = Minimum line voltage (V
11111 = Maximum line voltage (87V ± 20%)
Off-Hook Loop Current Monitor (3 mA/bit).
00000 = No loop current.
00001 = Minimum loop current.
11110 = Maximum loop current.
11111 = Loop current is excessive (overload).
