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 (87 V ± 20%).
The line voltage monitor full scale may be modified by changing R5 as follows:
V
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).
LVCS is backward compatible with Si2456/33/14 ISOmodems. The LVCS value is absolute
and does not reflect loop polarity. See U6C (LVS)[15:8] for 1 V/bit resolution and signed twos
