Notes:
1. In a CPE where AC power is not available, the designer may choose to switch over to line power when the CPE goes off-
hook and use battery power while on-hook.
2. The FSKE pin may be set low to prevent the alert tone, speech or other FSK inband noise decoded by FSK demodulator and
give false data when the dual tone alert signal is expected. If the FSKE pin can not controlled by microcontroller, the FSKE
pin must always placed in high state and the microcontroller must give up the FSK decoded data when the FSK signal is not
expected.
3. FSKE should be set high as soon as the CPE has finished sending the acknowledge signal ACK.
4. FSKE may be set low after the last byte (check sum) has been decoded or FCDN has become inactive.
5. For unsuccessful attempts where the end office does not send the FSK signal, the CPE should disable FSKE, unmute the
handset and enable the keypad after this interval has elapsed.
