Well, 16MBit is all I'm going to get apparently, at least with Vivaciti:
Why? Try a better modem and sync in the daytime, and you could well push near 20Mbps if youre lucky. And that's without tweaking the SNR from the modem side yourself. I presume you are already using a filtered faceplate if you have extension wiring, if not then maybe add a bit more.
It is a real 24 Mbit service, it's just that C&W has a slightly higher SNR margin than the norm of 6dB. And this goes for all resellers - not just Vivaciti.
As well as being prone to high latency (but low jitter), C&W's exchange equipment isnt exactly the best and even the 9dB noise margin needs increasing sometimes - so this is a sensible configuration and policy.
Also, if you move to a different exchange presence, especially one at or near capacity (Be/02?), don't be surprised if sync is lower for the same noise margin due to crosstalk and other factors.
