jhere is an old thread here about these.

http://www.geekzone.co.nz/forums.asp?forumid=49&topicid=16997

Does anyone have an updated source of these filters as I suspect the filter I have at home is on the way out. Intermittently there is noise on the fone line. When I unplug the ADSL router it goes away. Have tried with two different routers. Also I have been getting frequent BB disconnections since Sunday which I now put down to this as when it resets it's self the speed drops from 3.5meg to 1 meg untill the router is repowered.

Thanx in advance.

Regards,

Might as well get the newer VDSL2 one, anyone with a trade account at a electrical supplier could probaly get you one for $40-50.

Didnt realise you could get VDSL ones.

Are these ADSL 2+ backwards compatible?

Yes they are.

I'm not entirely sure what is difference between the older ADSL master splitters and the newer VDSL ones is, presumably frequency range they handle is wider in the VDSL version or something like that.

I believe if you have the older ADSL version you will need to update to the newer VDSL capable version if/when VDSL becomes available.

Thanx for the replies.

The new filter sorted it. Been 3 days now. No noise on the fones and the ADSL has been solid with no disconnections. The only difference I have noticed is that speedtest now shows 3.2Mbits as before it was 3.5Mbits. I can live with that..

The new VDSL2 filters are rated to 30MHz as opposed to 2.2MHz of the ADSL filter. They are totally backward compatible, so you can fit a new VDSL2 one even if you only going to use/get ADSL.

The new VDSL2 filters now have 3ports instead of the origianl 2ports. The green pair is the modem pair. In all VDSL2 filters I have seen to date the green(modem) pair is simply wired to the input (orange), so as yet none are providing a seperate HP section for the modem, if it should be needed.

Cheers

Thanks Cyril. Looks like its time to open a trade account with mastertrade for the VDSL2 splitter and all of the other parts I need for my project.

I have heard from some that the best place to wire the VDSL2 splitter is at the demarc. I am just wondering if it is possible to put the splitter in the outside plastic demarc box so its there for easy access in future (well ladder access as its on roof eves)

I would then run cat5e from the demarc to the centralised coms cabinet. I assume using two pairs of the cable from the splitter for POTS and xDSL? (modem port output)

Thanks

Hi, in the Demarc is one option and ideally the best, but if its inconvienient to put it in the ceiling space or under the floor is not a problem, the important thing is that the line that you latch into is a direct one from the demarc and has no taps or splits off to other circuits before the filter.

Ideally cat5/6 where possible, but cat3 or Ext2 (black external cable) is fine, its still of adequate performance compard to the multi pair from the exchange, the critical one is the clean non split line.

You are trying to implement a consistent transmission line between DSLAM and modem, with the POTs services in you house tapping in via the filter which will isolate any bad wiring on the voice/POTs side.
