there are some analogue areas on the telewest network.
The former CableTime areas are analogue (birmingham and liverpool/blackpool areas). but telewest have upgraded birmingham fully to digital and broadband, and they are about to fully upgrade the other cabletime area to dtv and bb.
the other area is former-eurobell, in the south-east (tonbridge area). it is still analogue, and no plans, of yet, to upgrade.
