1. The CPE designer may choose to set FSKE always high while 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
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
