Hi,

So I've recently moved back to an ADSL only area and heard the master filter is recommended in order to get the maximum performance on your line.

I've approached a company that's recommended by Geekzone (CTS), and they're happy to do it. I just have some questions about the terminology they use as I'm not 100% on this technology.

I asked them which make/model of filter they use and they said "We use the standard “in-line” filter that Chorus use (Sorry don’t know the brand)." I also asked if they need to know the location of my demarc and they said "Also location of demarc would be helpful however if you have a MASTER jackpoint in your premises with live DSL broadband connection then this would be best place to install filter.".

Does this seem like he knows what he was talking about? Is an "in-line filter" what I want, and is the jack point he's talking about refer to my normal phone point I'm already using for ADSL? I was under the impression the best place to install the filter was as close as possible to the source.

Thanks,

Glynn.

Q. Does this seem like he knows what he was talking about?

A. Yes

EDIT: My personal bias is that all ADSL and VDSL connections should have a master filter.

This is the first jackpoint in the chain because you want all your phones comming off the filter and the only wiring for your ADSL is the single jackpoint where you plug in your modem. that all helps increase the speed

Doesn't sound like he knows what he is talking about to me.

1) an 'in-line filter' is the crappy thing you plug into your phone jack point. (Just google image search, for in line filter ADSL and you'll see what I mean. This is not the same as a master filter.

2). An inline filter would go at the first or main jack point in your house. A master filter would best go at the demarc/ETP

Unless Chorus are suppliers of "the crappy things you plug into your phone jack points" I think you are jumping to the wrong conclusion. Plug in filters also go into more than the first or main jack.

This is what a master filter looks like.

I went back to try and get some clarification...

"The “in-line” ADSL filter we use is “hard wired” version we install across line before phone jack point.

So depending on your set up we can to install a second jack point for dsl modem and leave existing jack point for phone.

We can install filter at demarc (point of entry) if that is your preference."

That all sounds right. The "hard wired" filter is as per the pic above.

Ok, thanks. Should I request he puts it at the demarc or leave it up to him?

If there is an ETP, then this is where it should go. If the cable comes in directly to a first jack-point, then this is effectively the demark (or internal termination point); it can then go here instead. Make sure if it's the latter, then you really need to make sure it is definitely the first jack-point - i.e. crawl around under house, in ceiling space etc. and try and track where the cable comes in and goes etc. I've seen some supposed "first and only jack-points", to then discover alarm wiring or Sky jack-points to then be teed off before this supposed fist jack-point.

I'm in central Wellington, which is an issue as it's a block of apartments. Also, there is office space attached in the same building. Finding those points will probably prove a bit of a mission so I'd prefer to know where they are before he arrives.

If the connection goes directly to a master jack from the Darmac and then into modem (VOIP phone) is there any benefit to having a master filter?

Thanks, I had major issues when moved into house years ago with line dropping out so I cut all wiring out and installed new Cat5e cable from darmac to master jack so no other ports now. Sorted my problem but since Chorus has pushed our UFB out another year to 2019 I'd be more than happy to shell out a few $ if the master filter would have made any difference.
