Hi all. Just moved into a new house where the telephone sockets are all R11 and my filters are all BT. DSE don't seem to have any so any suggestions?

Hi, just to clarify do you mean RJ11 (4 or 6pin) or RJ45 8pin. RJ11's are not readily available in NZ except through the likes of Jaycar (as RJ11 is common in Oz). RJ45 however is common and the recommended format for houses wired with structured cabling layout and there are adaptors for those, but if wired in a structured manner a central filter should be used, infact I recommend that anyway.

Yea you will be doing well to find RJ11 to BT adapters. I would have thought they are RJ45's as Cyril says. Is there a patch panel anywhere? If there is you will probably find a 'DSL' point next to that as they probably installed a splitter when it was re-wired.

If they are RJ11 your best bet will be chop the BT off the filter and crimp on an RJ11. Or just install a splitter and then you can plug a standard line cord (RJ11-RJ11) in to the wall for both your phones and modem.

Any chance of some photos? Can soon tell then if it's RJ45 or RJ11.

You can buy RJ11 to RJ45 or RJ11 to BT adaptors and places like JA Russell or Ideal electrical. They are quite common

In a domestic suitation (Just like my place) I have RJ11 sockets for the DSL (and a central DSL splitter), BT sockets for the POTS and RJ45 for etherent, it makes it hard to plug things in wrong (not impossible though)

I've just stuck to RJ45 as that appears to be the direction Telecom NZ will go.

I've several CAT6 runs for Gigabit Ethernet the length of the house and CAT5 for DSL.

Have an old house wired for three wire phone connections and ~RJ25 jacks and not interest in rewiring the whole place, so sadly a mix of good, bad and CAT6.

I've 'cripped' a few RJ45 to RJ11 'tails' for phones in case the mood takes me to use one of my 'Ethernet' runs as an extension.

I just did a 'homerun' DSL connection from the VDSL2 splitter via CAT5.

Out of curiosity why did you bother with RJ11's?

I can think of an idea, but not sure if that was gregmcc's thoughts.

Some if not all RJ45 interfaces carry some sort of power voltage depending on device attached.
AND if one had power over Ethernet....

I have on at least one occasion walked away from a data centre with a sheepish look on my face, when I plug the wrong cable into an interface and 'blown' the device at the other end.

Not sure what HDMI over Ethernet carries in the way of power and pinouts.

At least I labelled my ADSL RJ45 outlet and the rest are 631A(whatever) so no confusion at home.

Simple, a wall plate with a F-connector for sky (marked sky), another F-connector for TV (marked TV), a RJ45 for ethernet (unmarked), a BT for POTS, adding a second RJ45 unmarked would only cause confusion when it came to plugging the DSL modem it seemed like a good idea to use RJ11 as the sockets were off the shelf.

Remember in the electrical world it is a really bad idea to have two types of connectors that are not electrically comptiable, the best hope is that no damage occurs, the worst case is things blow up, that's why different connectors should be used for different things.

Ok. The person who was in my place before me was using it as an office and it has a PABX and various plugs everywhere. I got Vodafone in (Chorus actually) and they fixed it up for me

They are quite easy to find if you know what to search for.. They are usually known as RJ12's :-) RJ11 and RJ12 are the same except RJ11 have 2 wires and RJ12 have 4 wires terminated which makes no difference really for the home situation.

so..

is what you need.. RJ12->BT adapter..

I thought RJ12 was normally the 6-wire version, still the same plug anyway. I could send you some RJ11 filters if you really need them, but is easier to just change the plugs on your existing filters. You need a crimping tool to do it.

Power over ethernet is the same voltage (but different wires) as the phone so at least it won't damage your ADSL modem if they get mixed up on RJ45 outlets.

Time to find a new industry!

There are no issues with plugging differnt devices into an RJ45 as they're all designed to work together, you can't damage anything.
