Represents either the line voltage, loop current, or on-hook line monitor depending on the
state of the MODE, OH, and ONHM bits.
On-Hook Voltage Monitor (2.75 V/bit).
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 = Loop current is less than required for normal operation.
00001 = Minimum normal loop current.
11110 = Maximum normal loop current.
11111 = Loop current is excessive (overload).
Overload Detected.
This bit has the same function as ROV in Register 17 but will clear itself after the overload has
been removed. See "4.15. Billing Tone Detection" on page 19. This bit is only masked by the
off-hook counter and is not affected by the BTE bit.
0 = Normal receive input level.
1 = Excessive receive input level.
Recal/Dropout Detect.
When the line-side device is off-hook, it is powered from the line itself. If this line-derived
power supply collapses, such as when the line is disconnected, this bit is set to 1. Sixteen
frames (16/Fs) after the line-derived power supply returns, this bit is set to 0. When on-hook,
this bit is set to 0.
0 = Normal operation.
1 = Line supply dropout detected when on-hook.
Overload Protect Detected.
0 = Inactive.
1 = Overload protection active.
Note: See description of overload protect operation (OPE bit).
