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 (Vmin = 3.0V ± 0.5V).
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).
Overload > 140 mA in all modes except TBR21
4:0
LVCS[4:0]
Overload > 54 mA in TBR21 mode
