For information regarding the communication function of the KeyStoneⅡ

1)
KeyStoneⅡ do you raise the throughput by a dedicated accelerator?
(For 11ac of correspondence)

From my understanding, No. What do you mean by "For 11ac of correspondence"?
Please refer the throughput performance guide of keystone devices from below link.

KeyStoneⅡ Is it possible to TDM packet data received?

The current keystone II devices does not support McBSP(TDM packet data). Please refer device data manual for supported peripherals.

2)
KeyStoneⅡ the EC / NC with Voice processing, you can non-compression conversion to H.711?
4)
KeyStoneⅡ Is it possible to RTP relay?
(LAN to handle Can you but want to process with no CPU load on the LAN in the router function?)

This is of course achievable and can you please provide the kind of application you are developing.
