Notes:
1. The CPE designer may choose to set FSKE always high while the the CPE is on-hook and the FSK signal is expected.
2. TW/P & E/312 specifies that the AC and DC loads should be applied between 250
400 mS after the end of the ring burst.
3. TW/P & E/312 specifies that the AC and DC loads should be removed between 50
150 mS after the end of the FSK signal.
The W91031 may also be placed in a sleep condition.
4. The W91031 may not be woken up at the first ring cycle after the FSK data had been processed.
