Re: Virgin Media laying fibre in established VM areas?
The VHUB acts as a multiplexer, condensing down up to 3000 subscribers into trunks of 16f back to a headend/hubsite. All CMTS and broadcast equipment is still in the technical sites, the VHUB is just acting like a massive collector node/amplifier.

The star topology you refer to was the ex-Telewest network (point to point PDH generally) while the NTL network is generally built on fibre rings (redundant SDH).
