Phone extension wiring
I rerouted a phone extension in my house recently and wired it back up the
same way. It was working fine until a couple of days ago. Now when I pick up the phone on the extension, the main phone starts ringin - either that or there's just no dial tone. I've checked the wiring to make sure it's not loose....any other ideas? Ronnie |

Are you *sure* you rewired it the correct way - allowing for the fact that the numbering on most extension sockets is the *reverse* of that on the back of the BT linebox? With line on 2 & 5 and ringing on 3, a ringing extension when going off-hook indicates the phone is wired across 2 & 3 (shorting the ringing cap and the phone ringer is responding to DC on the ringing wire) instead of 2 & 5.

As well as other posters have answered, check you have made the connections properly (the proper tool (or clones of it) is called a Krone Tool), but also carefully check that the cables on terminals 2 and 5 are not transposed at any point, because the symptoms you describe can be caused by this. -- Mark Please replace invalid and invalid with gmx and net to reply. |

I took a photo on my digital camera before I started and used the same extension box when I'd rerouted it. Would it have worked at all if I'd got it wrong?

Something must be shorting I guess. I'll have another look at it. Maybe it's a connection further back in the wire that I've pulled loose or something? R |

Yes - if you had also not got a good contact on pin 3 which is quite possible if you were using a plastic thing to insert the wires. -- Peter Parry WPP Ltd http://www.wpp.ltd.uk Antenna solutions for car, caravan, house, office, boat and tent.

Using a screwdriver etc is likely to damage the contacts. You need a parallel faced 'pusher' of exactly the right thickness - especially if fitting two wires to the same connector. -- *Windows will never cease * Dave Plowman London SW To e-mail, change noise into sound. |

You need a parallel faced 'pusher' of exactly the right thickness - especially if fitting two wires to the same connector. The blue pushers are fairly goof proof, but putting ascrewdriver just to one side and pulling on the wire works too - and its much quicker IME than finding the blue thing! For newbs, chances are they wont have a blue thing, and dont need it. Its only if you stick the screwdriver down the centre that things go wrong. NT |

Thanks to all who replied to my question.
You'll be pleased to know that I got it fixed The discovery of the actual problem was purely chance. I was opening the extension socket box for about the fourth time to check my connections when the pin 3 wire(orange with white stripes) popped out - but not at the connection. Looks like the wire had severed at the point where the outer sheath of the telephone stopped but the point of breakage was just enough inside the sheath to hold the wire in there so you couldn't see that it had snapped. Stripped the wires back and reconnected...sorted! Thanks again. Ronnie |

Analogue has artefacts too (non-linearity, diff. phase and gain errors, PAL cross colour, etc., etc.). I find I rarely notice MPEG artefacts, but find almost all off-air analogue TV pictures look slightly noisy now. I'm firmly in the digital's miles better camp, but others will disagree. [DECT] It can never be better than analoge because it has a d/a and a/d converters and the transmiter and receiver then it just goes in the same analoge socket my phone would go in. The comparison was with analogue cordless phones. The noise and distortion introduced by the DECT codec is much less than that introduced by the analogue radio link in the older systems. DECT is a really good system. -- Andy |

I frequently record off the phone line, and a DECT phone sounds pretty much the same as any other good hardwired one. BT restrict the bandwidth at 'their' end. The quality difference is like comparing freeview to analoge TV. Aspect ratio apart, most would be hard pressed to say which was which, assuming good reception. -- *When cheese gets it's picture taken, what does it say?

I don't watch fitba so the most common one is of no interest. If you are comparing overall picture quality Freeview is superior to analogue. In the same way DECT, unless you he ave some very poor ones, is at worst indisguishable from wired phones and often somewhat better because the signal processing opportunities are greater. It can never be better than analoge because it has a d/a and a/d converters and the transmiter and receiver then it just goes in the same analoge socket my phone would go in. It can (and often is) considerably better in that the opportunity to do some nice signal processing exists and has low implementation costs. Whilst one could do similar on a POTS phone (and a few do) it would make it more expensive. Yea they are cheap and also easy to set up an exchange with, The PABX is a hard wired ISDN one :-) but a bit like comparing wireless to wired LAN, wired is best. The comparison is invalid. There are numerous technical and security differences between wired and wireless networks. No such differences exist between DECT and POTS (except that DECT has a considerable amount of call management capability which POTS by itself does not). I once tried my *expensivish* phone in the analoge port of my old T/A and I can say its a pitty we cant have a fully digital phone network We have, at least to the handset. The Siemens DECT are ISDN, the Phillips and Panasonic DECT use analogue POTS extensions. There is no noticeable difference between them. -- Peter Parry WPP Ltd http://www.wpp.ltd.uk Antenna solutions for car, caravan, house, office, boat and tent.
