Carrier Loss Detector.
0 = Default.
1 = Caller ID sensitivity can be increased by 5 dB. When CLD = 1, the host is responsi-
ble for terminating caller ID reception by asserting an escape and issuing the ATH com-
mand.
Note: This bit also controls the carrier loss detection of non-caller ID modes of operation.
Overcurrent Result Code (“x”).
0 = Enable.
1 = Disable.
Low Loop Current (required for CTR21 operation).
This feature only works when SDF ≠ 0x00.
0 = Disable.
1 = Enable.
Wake-On-Ring Alert.
0 = Alert is not asserted upon a wake-on-ring event.
1 = Alert is asserted upon a wake-on-ring event SE2[7:6] (GPIO4) = 11
Hookswitch Flash Result Code (“f”).*
0 = Disable.
1 = Enable.
Intrusion Result Code (“I” and “i”).*
0 = Disable.
1 = Enable.
No Phone Line Result Code (“L” and “l”).*
0 = Disable.
1 = Enable.
Ring Result Code (“R”).*
0 = Disable.
1 = Enable.

Therefore, the host must set CLD = 0 prior to answering a call via “ATA” or initiating a call
via “ATDT” or “ATDP”.
