Langley used a completely different Divicom setup.
All the equipment in customers homes will be very similar, with similar required power levels, I can't see why the Telewest boxes need a better SNR than the ntl networks unless the network is noisier.
We now both use the Ambit 256 modem on all networks.

Telewest SNR is supposed to be between 29db and 50dB.

NTL can go below 26dB and sometimes can get lower and still work.

Three different platforms within what is now one company.

Knowsley, Langley and Bromley all have differences, such as SNR and also the Downstreams differ between all 3 platforms.
