Overload Detected.
This bit has the same function as ROV, but clears itself after the overload has been removed.
See the “Billing Tone Detection” section in “AN93: Modem Designer’s Guide”. This bit is not
affected by the BTE bit.
Line Voltage Status.
Eight bit signed, twos complement number representing the tip-ring voltage. Each bit repre-
sents 1 V. Polarity of the voltage is represented by the MSB (sign bit).
0000_0000 = Measured voltage is < 3 V.
