    Hi folks,

    Well, as subject really, anybody know?

    BT combined wall socket and filter thing to ADSL port on the back of a
    router. RJ11 (?) on each end.

    Thanks for reading.

  2. how long is a piece of string, well wire in this case.

    The attenuation of the signal should not be an issue if its a decent
    cable, however if you have a weak signal (as implied by the BT
    installed socket filter) there is some risk of collecting interference
    unless you use a decent quality twisted pair phone or network cable.

    People have reported succesfully running long runs of Cat 5 from a
    faceplate filter - 10s of metres. You can use RJ45 plugged off the
    shelf network cables and an RJ11 female-female coupler to plug the
    modem into (ebuyer et al do them)

    If you use a flat (generally non-twisted) cable, I would say about 10m,
    maybe a bit longer if you can keep it away from sources of interference. If
    you can find decent twisted-pair with the right connections, well you might
    already be several miles from the exchange and are basically extending that
    (although to some extent the BT master socket and optional microfilter will
    place further limitations).

    In an earlier contribution to this discussion,

    Quite a few tens of metres - most likely more than you need! But if it's
    more than a couple of metres, make sure that you use proper CAT5 cable.

    Thanks for all your insights.

    I think I'll see what my local computer shop can come up with.

    Thanks again.

    In an earlier contribution to this discussion,
    If you're planning a long extension, the easiest way is to buy a modified
    ADSL faceplate and an RJ11 or RJ45 socket from Clarity [see
    http://www.clarity.it/telecoms/adsl_bits.htm] and to use CAT5 cable - kroned
    into the *back* of the faceplate - to join the two together. You then need
    just a short RJ11-RJ11 cable between the remote socket and your router.

    My (wifi) router is at the end of two ordinary phone extension cables, total
    of 15m, from hall up to loft.
    Works perfectly on 1Mb/s PlusNet service, ~5km from exchange.
    Regards,
    Martin

    If your line quality is good then in principle you can plug in several
    kilometres of extension and still have a viable ADSL signal.
