Function

Reserved Read returns zero.
2OVL
Receive Overload Detect.
This bit has the same function as ROV in Register 17, but clears itself after the overload is
removed. See “5.18.Billing Tone Protection and Receive Overload” on page 31. 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.
1DOD
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 the 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.
0OPD
Overload Protection 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).
