Per la 20mega (target noise 6db) avevo trovato questi:

Profilo: i143 ATUC Rx (Upstream) ATUR Rx (Downstream)
Target Noise Margin 6 dB 6 dB
Max Noise Margin 31 dB 31 dB
Min Noise Margin 1 dB 1 dB
Min Bit Rate 448 Kbit/s 5024 Kbit/s
Max Bit Rate 480 Kbit/s 22240 Kbit/s
Planned Bit Rate 480 Kbit/s 22240 Kbit/s
Max Interleaved Delay 16 msec 16 msec

Profilo: i142 ATUC Rx (Upstream) ATUR Rx (Downstream)
Target Noise Margin 6 dB 6 dB
Max Noise Margin 31 dB 31 dB
Min Noise Margin 1 dB 1 dB
Min Bit Rate 320 Kbit/s 896 Kbit/s
Max Bit Rate 480 Kbit/s 22240 Kbit/s
Planned Bit Rate 480 Kbit/s 22240 Kbit/s
Max Interleaved Delay 16 msec 16 msec

Varia il Min Bit Rate: suppongo i43 sia per Linea+Iptv e i42 per solo Linea, ma non ne ho la certezza.
Qui ci vorrebbe Gherf per conferma e per la lista completa.
