The 2Mbit service on the Langley and Bromley platforms has always been 200000 bits/second, while on Telewest Knowsley it has always been 256000, so Knowsley have always had 56k more upstream on the 2Mbit, and that's about it. Not much more to say on that score, it's a difference in the config files between the platforms.

They are not encrypted, they have an MD5 hash incorporated into them. I realise that they are referred to as being encrypted but that's not the case, they are using the hash as an integrity check to ensure they haven't been diddled with but that's about it, the configs themselves remain easily readable via a DOCSIS config viewer.
It prevents obtaining extra upstream by feeding the modem a modified config file but does not alleviate the issue of cloned modems, this can only be addressed via dynamic config files and BPI+, utilising the public keys and certficates built into the modems, but requires a migration of the network to DOCSIS 1.1.
