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.
