Re: Are NTL pushing the system too far?
As pointed out, its strange that you lost telephone and Broadband but not TV. I would stick my neck out and guess it was something hubsite related, possibly they changed a piece of equipment during hours instead of out of hours for some reason.
The telephone would of been backed up by battery at the mux cabinet if there was a power outage, so you would of lost TV and broadband. The Hubsite seems to be the only common link between the two services going down and not the other.
The Broadband signal is usially inserted as an RF signal before the optical transmitter in the hubsite, so I guess something common to either mains for the optical TV receiver or the optical feed for both Telphone and TV were lost.
Possibly someone disconnected the wrong thing ! That is very possible since they have lost many of their technical people through redundancies and people walking away.
The battery ups backup project for all CATV nodal cabinets was put on hold back in 2000, some old flakey power supplies (ntl bought unsuitable ones for the job and installed them incorrectly) were replaced as and when they failed, I dont think the project was revisited due to further cost cutting.
A lot of ntl's network has many single points of failure and in many cases it was down to speed to build, with the intention of sorting out diverse routes and back-ups at a later date. The financial difficulties have sadly taken their toll on ntl.
