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 W91030B may also be placed in a sleep condition.

4. The W91030B may not be woken up at the first ring cycle after the FSK data had been processed.
