    Default A Telephone Query

    Hi All'
    The phone line conects onto the house, the point of entry. From there it loops to all the phone sockets in the house, in series. Up to 5 connected with a phone or somesuch is the max .

    Is it possible to run another circuit from the point of entry in parallel with the first? Would you then be able to run another 5 sockets off that line? PJ

    Now I am older, I listen but cannot hear.

    If it is not broke, don't make it broker by trying to make it better. (This applies specifically to PJ)

    Anything is possible, whether it is sensible is another thing.

    There are two issues

    1 The ability of the ringing generator to ring more than 4 or 5 telephones at a time. That doesn't change.

    2 The affect of all this wiring on Broadband frequencies. A central splitter is better than filters on each working socket because it isolates any wiring stubs.

    I wired our house with ample sockets and now have just 1 Uniden cordless base station that supports multiple handsets and 1 old corded phone in case the power goes off. Both are plugged into the same socket using a double adapter.

    I question all the phones being in series John, but here is a link that may help explain telephone connection methods. http://www.telepermit.co.nz/PTC200X12.html#sec10.3

    you can run as many sockets as you like, your just limited by the number of devices you have conected (phone, fax, modems). some devices have higher "load" than others (ral number??) so that can limit the amount even more.

    homes are usually wired by cost rather than performance. you may have series or parrallel or combo of both.
    most are wired by those who are not responible for it hence they don't really care how its done.
    Tweak it till it breaks

    Electrically all sockets are wired in parallel.

    The term "series" refers to sockets being daisy chained one after the other rather than wired in a "star" format with each socket wired back to a central point.

    By Series I meant, daisy chained as stated above & // was each socket taken back to the POE.

    Any way I have got the message. Thanks all. PJ

    John: They should all be wired in parallel, not series.

    Have a look at the phone jacks that you are using. One should be a main (or primary) and all the others should be secondary.

    The main is difference is that it has a circuit (I think it is a capacitor) that separates the ringing current from the speech current (80v AC and 50v DC) and you should only have one in the circuit and it should be, as the name suggests, the main one, the first in the line.

    After that, you should be able to put a secondary jack in every room, including the loo, without too many problems.

    I wired my house for multiple jacks nearly 30 years ago when multiple jacks were not common. I had a phone in nearly every room. Most convenient.

    These days I'm not too certain why you would want to do that unless you have a fax in every room, or at least something such as a fax, that needs a direct connection.

    Portable phones are much more convenient and, obviously, you only need one jack point. Just remember to keep it in your pocket through the day and by your bed at night. Isn't modern technology great?

    Incidentally, I wonder at many people who have a portable phone but don't use it as a portable phone. They leave it on the charger all the time. The only time it seems to go portable is when they are using it. Then it goes back to the base. Why bother, I wonder? Would it not make more sense to carry it on or about your person? Most peculiar.

    We've covered the series/parallel aspect. the modern jacks are electrically in parallel, it's the physical layout of the cable route that is being described.

    30 years ago the wiring was more complicated and some parts were in parallel but the ringing wire was truly in series with contacts in each jack to replace an absent phone.

    To be fussy

    The Telecom standard layout is now "2-Wire", there is only 1 type of jack marked with a "2". Master and secondary jacks are a relic of the previous "3-Wire" standard. All 2-wire jacks have their own capacitor. Since new phones have had their own capacitor built in for many years, there was talk that the capacitor would be removed from new jacks.

    The 3rd ringing wire causes an imbalance to earth that becomes significant at broadband frequencies.

    Te be even fussier

    In Telecom's latest Code of Practice for residential cabling they say not to differentiate between computer/data outlets and phone outlets.
    They are now called a Telecommunications Outlet or TO and are RJ45 sockets.
    You have to use at least CAT5 cabling all wired back to a central location.
    Any outlet can then be made to be for a phone or computer network just by swapping a patch lead at the central location.
