I am moving up to my mum's place in Whangarei where I strongly suspect adsl has never been connected.  When I used to dial in to the internet on visits in the past, it was slower than molasses.

Anyway, I bought a master filter to install and had a look at the wiring on a previous visit.  I knew there was some sort of Telecom box (Tucon 852 FM 1+1 SCE) in the spare room connected to the phone system and when I got under the house to follow the wiring, I discovered some sort of device wired into the phone line where it emerged from the ground.  I finally found a torch and it is an Ericsson Carrier Isolation Filter, Tucon 810.

So I do some web searching and get nothing even after telling my search engine that I know how to spell Tucon and I am not misspelling Tuscon.

I guess it is some sort of alarm system and that the (unkown) filter on the line should be removed as soon as possible and replaced with my (known) adsl master filter...  Can anyone confirm this?

I prefer to have some idea what I'm doing before I start hacking things.

Also, I have no current connection at the house so I can't do any actual testing yet.  The wiring thing was part of deciding what telecommunications provider to go with.  I really wanted fibre (to circumvent the crap wiring in the house) and would probably have gone with Snap if they had agreements in place with North Power (the fibre provider in Northland), but they don't and fibre is not going to be a short term solution anyway due to the consenting and installation process (I have a shared driveway).

So in the short term I am probably going to have to go adsl...
