Quick question, with a "Connection and Wiring" ADSL install from Telecom I end up with a dedicated Jackpoint labelled ADSL, now this is, I believe, a standard BT jack. From recent experience most ADSL modems come with a cable that has RJ11 connectors at both ends (I seem to recall some years ago the cable was RJ11 one end and BT jack the other). So the question is, do I need to use a filter as a BT jack to RJ 11 converter as obviously I cannot plug RJ11 into BT jack

The filter should have an RJ11 connector. Plug your cable into this and use it as an adapter. To clarify, the filtering is on the phone side, not the modem side so it's just an adapter.

If you have received a full install from Telecom then you will have had a filter installed.

All you need to do is locate a RJ11 to RJ11 cable (not filter) plug your modem into the socket labled ADSL.

if you don't have one, DSE will sell them.

I've had a splitter hardwired and have a dedicated ADSL jack. But the modem cable is RJ11 both ends. Had a quick look on DSE and I can pick up the correct cable for $15.00 or so. I'm sure the old M1122s used to come with a BT Jack/RJ11 cable (yes it's been a while!)

Did your modem not come with a filter?

Yes it did but I've had issues with them in the past and would rather not use them. Given I've had a splitter installed there should be no requirement for filters...... well that was my understanding

If you have a filter, use it. The RJ11 socket is not filtered it will function as an adapter, only the BT socket where you would plug a phone in is filtered. I'm not going to get into the nitty gritty of the whole thing but trust me it will work. The RJ11 side of it is just an adapter.

So you have a regular BT jack on the wall or a RJ11?

Cheapest place to buy a BT to RJ11 cable is from the various $2 stores around the place. Most sell cables for $2, some $3.

The $2 Shop is a good supplier of basic items like that. Cheaper than anything branded (or even non branded but from DSE etc) and as there's nothing to them there's no real need to pay top dollar.

Handy when your modem isn't supplied with a filter, which still happens with some models/brands.

Just dont use a adsl filter from a dollar store - they are somewhat crap.

Not seen any $2 shops for quite a while now. they all seem to have rebranded and sell more expensive things too.

Very true.

We still have a $2 shop, and also a heap of similarly named shops selling the same er 'junk' for sometimes more than $2.
