Receive Overload Detect.
This bit has the same function as ROV (Register 17), but clears itself after the overload is
removed. See “5.22.Receive Overload Detection” on page 28. 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. This bit will read 1
when loop current is not flowing. For example, if this line-derived power supply collapses,
such as when the line is disconnected, this bit is set to 1. Additionally, when on-hook, and the
line-side device is enabled, this bit is set to 1.
0 = Normal operation.
1 = Line supply dropout detected when off-hook.
Overload Protect Detect.
This bit is used to indicate that the DAA has detected a loop current overload. The detector fir-
ing threshold depends on the setting of the ILIM bit (Register 26).
