Master phone sockets.
I know that 'by-the-book' you are not supposed to interfere with the
wiring on the supplier side from the master socket. However setting aside the legals is there any technical reason why it would be bad to add an extra phone socket off the main pair using a second master socket? There is a nice little junction box inside the flat just on the other side of the wall from where I would like the extra socket. The 'correct' route would mean a long and involved path on the customer side. TIA -- Ed Sirett - Property maintainer and registered gas fitter.

It's not a good idea. You'd be paralleling up the capacitors that make
the ringer work, best bet would be to run a cable back the way from the master sockets 'client' side to where you want the new socket to be. |

However setting aside the legals is there any technical reason why it would be bad to add an extra phone socket off the main pair using a second master socket? Yes, you will have two ringing capacitors in parallel. There is a nice little junction box inside the flat just on the other side of the wall from where I would like the extra socket. The 'correct' route would mean a long and involved path on the customer side. If you've got a two-pair cable from that junction box to the master socket you can run a ringing wire back from the master socket using a spare wire in the second pair. Extensions don't have to be electrically downstream of the master socket, although in theory-strictly-compliant they should be connected via the pluggable faceplate on a Linebox or a plug-in adapter. Alternatively, move the Linebox to the location of the master. Alternatively, many electronic phones don't need the third wire for ringing. Owain |

TIA Could you not then make the new socket the master, run a cable back to the point of the junction box, stick another junction box next to the original and run the old master as an extention? |

There is a nice little junction box inside the flat just on the other side of the wall from where I would like the extra socket. The 'correct' route would mean a long and involved path on the customer side. The usual advice is that you are not really supposed to have more than one ringer capacitor on a circuit, but it *does* work. I have wired three houses with extensions using exclusively master sockets and only the pin 2&5 pair. House 1 had seven such extensions (and one master) altogether (though only six had instruments attached), house 2 had six extensions and house 3 has five extensions (at the moment, three more planned). So that's my own experience, but consider this: I have, in the course of things, taken apart several ADSL microfilters. Not one was wired up as an extension socket. Every one of them took just two wires from the phone line, did a bit of LC filtering and then had a ringing capacitor hung across the "phone" outlet. These are all BABT approved and are designed to be plugged into every telephone socket in the house. You'd end up with an all-master installation that way. Having said that, I did see a cunning trick performed on a BT installation once: Incoming line runs through attic. One of those little four-terminal junction boxes in the attic with separate wires running downstairs to "master" socket in the hall, and into a bedroom to a secondary socket. There was no second wire between the master socket and the secondary, so how did phones on the secondary ring? The answer is that although the two line wires effectively went directly from the JB to each of the other sockets, the third (ringer) wire was brough back up from the master using one of the unused wires in the installation cable, and thence down to the secondary. Difficult to explain, and difficult to draw in ASCII, but I'll have a go: ________ incoming ========JB========secondary ||| ||| ||| master If you don't want to go the multiple-master route, and you don't mind fiddling with BT property, would this be a suitable solution, assuming there is a spare wire in the cable between junction box and master?

(Capacitors are not in parallel as someone else said, because you do not connect the bell wire (3) between the two master sockets.) It only becomes a (slight) problem if you use pulse dialling and have any phones sensitive to bell tinkle, as you have lost the function of the bell wire between the two master sockets to supress bell tinkle, and you could get one phone's bell tinkling as another phone pulse dials, although it's harmless. -- Andrew Gabriel |

Since the ringer can alternatively be placed directly across the A+B lines (i.e. like the capacitor was shorted out as is done by phones which don't use the bell wire), it's irrelevant. It's not, because A+B ringers are electrically equivalent to capacitor + bell, ie they do not pass DC. If the capacitor is shorted then there is (a) DC on the ringing wire, which can cause some electronic phones to ring, because they are sensitive to both DC and AC on the ringing wire; (b) a DC loop across the speech pair, which will cause ring trip.

The message
from Martin Angove contains these words: The usual advice is that you are not really supposed to have more than one ringer capacitor on a circuit, but it *does* work. I have wired three houses with extensions using exclusively master sockets and only the pin 2&5 pair. House 1 had seven such extensions (and one master) altogether (though only six had instruments attached), house 2 had six extensions and house 3 has five extensions (at the moment, three more planned). Not only can it be done, but it's the standard answer if there are more phones on a single extension than can be rung by the available ringing supply. The late and sometimes lamented Omnicom telephone exchange had many faults, as well as many virtues, but the most tremendous thing about it was the unfailingly helpful and laid-back Welshman on the end of the helpline. He recommended using only master sockets on the extensions. The only disadvantage, of course, was that the phones didn't start ringing until the capacitors had all charged sufficiently. With American-style internal exchanges, of course, master sockets are usually a necessity. When I replaced our internal exchange I had to buy a supply of capacitors to fit into the slave sockets around the place. |

different, as well as needing a fleeting earth to seize the linefinder. I know they were not intended to be used for party lines, but in several cases they were. The problem being there was still party lines around when the LJU's came out and the old type jacks were discontinued. The old type of phones could have the bell circuits modified from series to parallel by re arranging the links and fitting a new lead. |

I don't think BT engineers are too bothered if you fit your own sockets as long as they are wired correctly. I was just looking at our master socket and I never noticed before that it is one of those NTE5 sockets with the removable lower front plate. Saying that, I've really not had a need to investigate before as there was a slave socket in virtually every room when we moved in 5 years ago. |

http://www.wppltd.demon.co.uk/WPP/Wi...telephone.html (but I don't quite understand the parenthesised part of your reply) I was refering to the fact that the page link has two master sockets shown - the NTE5 (with removable faceplate section that lets you connect /disconnect the secondary side of the phone wiring by simply unplugging it), and the older master socket that it a one piece face plate. The NTE5 shown on both sites is the same - two (screw) terminals in, six (IDC) out, no earth connection. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

I get the imporession they call it a PBX-NTE5 on the gorunds that is the only legit place and end user could install one ;-) The IDC-input version of the NTE5 is called a CTE5. If the N stands for network, what does C stand for? -- Andy |

If the N stands for network, what does C stand for? Customer? By definition, a non-IDC input wouldn't be much good for connecting directly to typical network wiring. -- Bob Eager begin a new life...dump Windows! |

If you look at the manufacturer's site: http://www.austin-taylor.co.uk/dist/pdf/atlj02b.pdf They suggest the CTE5 might be used on CATV cable drops... -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |
