So, they can't all be like that. that is how I remember it from my friend's Cambridge Cable. One coax, a magic box, then cable modem on one socket and a standard BT style phone on another. I should cross post this to cam.misc as they are all on it over there. My memory is of a figure of eight cable that was something like coax and cat 5. Co-ax, RG11 IIRC and a two pair copper phone cable often referred to in the trade as "Sidecar cable" Right: Given that it's you Tony, I take that as authoritative. So instead of using - say - baseband POTS and RF muxed on the one cable, they run a separate pair for de dog and bone..but in the same sheath? Yep co-ax for Internet and TV, and Two pair's of copper for up to Two phone lines.. In the same figure of 8 cable.. -- Tony Sayer |

So we have (a) God amongst us, do we? Perhaps I should bow and scrape ... Sarcasm will get ye nowhere;!.. Actually, RG6 is the norm ... One or the other. Seem to remember one of their local engineers referring to it as 11 .. Engineer that was, not installer;!.. So instead of using - say - baseband POTS and RF muxed on the one cable, they run a separate pair for de dog and bone..but in the same sheath? It's a figure-of-eight so that the cable can be split into its component parts with each fully shrouded. Do these help? http://i260.photobucket.com/albums/i...G6_Siamese.jpg http://i260.photobucket.com/albums/i...G6-Siamese.jpg -- Tony Sayer |

That's ok for DTV and Broadband[1] but the twisted pairs are needed for a telephone - if the sub doesn't want the 'phone, there is no need for UTP, though VM seem to insist on a 'phone as part of the package these days. [1] In cabled areas, broadband isn't ADSL on a telephone line - it is provided at RF (my current downstream is at 586.75MHz). In fact, the broadband signal is indistinguishable from a DTV mux on an analyser (except in some former NYNEX areas where the first broadband service uses a 6MHz bandwidth instead iof 8MHz, though I would expect that that might have been changed by now.) The point is that telephony is still done on twisted copper and is still completely separate from the other services. -- Terry |

So we have (a) God amongst us, do we? Perhaps I should bow and scrape ... No, but a man who does a lot of this sort of thing for a living. I am well aware from posts here and elsewhere that Tony has an excellent technical background but ... Googles "A career that spanned TV transmitters up to 40 kW transposers to 2 kW ReBroadcast receivers and demodulators , AM Transmitters to sever hundred kW and FM to some 40 odd.. Audio equipment by Rupert Neve and Audix, Pye TvT, Work with the UK radio communications agency radio communications investigation service, the BBC, Cambridge university, cellular and communication radio sites broadcast sites..." ... I don't see anything there about CATV or Virgin Media or any of its many predecessors - but then, perhaps I didn't find the full CV ... FYI Terry we supplied them with Two way radio systems when they first started round here and then they rolled out Anglia cable in Essex and Herts. Used their network for Point to Point audio circuits and spent quite a bit of time in their head-ends at Cambridge, Colchester and Bishops Stortford.. Same systems also with Bell cablemedia in Peterborough and Narwich and Nynex Manchester Liverpool Lancs..and etc further North... And their installer companies too... All before nthell swallowed them up;!!.. -- Tony Sayer |

Well young man, you seem to know what you're talking about, but round here they just seem to have the coax coming in. Maybe the twisted pair is taken from outside the house somewhere, but if so I've never seen it. I've prized open a few of those boxes on the outside wall and seen nowt but two coaxes linked with a line connector. Maybe I missed something. Bill |

However, I never came across any* system where the domestic phone used the same coax as the TV - or, in fact, any coax at all. The two were (and still are) essentially chalk and cheese. *Apart from experimental and speculative systems, trials etc. I, myself, even once went to Hungary to help show it could be done. -- Ian |
