NTL have a larger user base, hence more traffic. lets take the figure of 300,000 10mb users more users than telewest.
300,000 more users would need at least 1tb link to multiple transit providers around europe, US etc,
Whats the lead time of getting these type of fibre links installed ? and the equipment required to handle the task?
Its not just a case of upgrading what NTL own, its all about capacity and lead times, fibre links, equipment etc,
I still think NTL are doing a great job and one day NTL will win the UK cable battle.
