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...

The Tucon 852 1+1 system was emplyed by the post office /telecom in the 1980s amd 90s to allow for two voice phone services to be delivered down one set of cable pairs with one physical lne and one phantom line hence 1+1

It is obsolete technology - and it would interfere with dial up and absolutly with xDSL

In this instance it looks like both lines ended at the same address ( that is more than likely why it has never been removed). The Filter is on the incomeing line side of the physical line to filter out the carrier signal -much like an ADSL master filter is used today- and the Tucon 852 FM 1+1 SCE unit will be connected to the line before it to provide service to the phantom line.

Unless you are realy compitent with house phone wireing I would leave the job of removal to the experts - so I would get your mum to log a request with her provider to have the filter and unit removed by chorus (there should be no charge as even thought its in the house wireing as these devices are legacy network equipment)

The 1+1 would have made dialup unbearably slow. From memory a modem would only connect at around 9600 with one of these in place to split the line between two customers.

These days from the 80s and the vast majority were ripped out in the early 90s, it's quite a find to actually still see one around!

If you do get them removed I would love to get them as they would be perfect for the Telecom Museum as they are quite hard to come by these days. As Steve and Chorus said they are legacy equipment mostly removed around when dialup and faxes started to become mainstream due to the interference on the line.

Edit: are you sure you can't get vdsl? Since if you can you get a free master filter install if you sign up with Telecom. Plus Northpower fibre will be available with Telecom shortly.

I know when a 0+2 is provisioned on a line it shows up in ICMS.
Being that the 1+1 are much older I wonder if they show up in ICMS too. What I am saying is that when you ask to get your line put on Chorus will hopefully work out that there is a 1+1 on your line and send out a tech who will be able to remove this for you.

I don't understand why the OP used a subject "Guaranteed for sure 101% my house wiring is not at fault..." when in fact the wiring would be a major problem...

Sounds like the wiring is 101% at fault

Sam - the 1+1 line in this case wouldnt be noted in ICMS as the second line (phatom) l would have been removed from the records, as its at the same address, when the exch equipment was removed.

what would a 0 plus two and a one plus one look like, moving to a house that is semi rural, which
has had a second line in the past,

0+2 is a metal box about a4 sized that goes up a power pole making 2 phonelines over one pair. They were nothing but trouble when I had a line thru one to get a 3rd line into the house back in the dialup BBS days, despite telecom saying they were great because they were digital and "like isdn"

Friend ended up with 2 of the powered 1+1 units in their dads office out the back of the house for his work and fax lines, since they had 2 lines into the house for phone and the computer - it munted the phone line for dialup and the fax never worked properly. Soon after the lawn was dug up and another cable put in to get proper phonelines.

I dont get why the 0+2 never worked well for dialup as I would have thought it would be great taking the A/D and D/A conversions so close the where it is being used compared with taking it for miles back to an exchange, but they were aweful - I think 26400 was about the best I could get thru it.

The 0+2 feild units come in two different varietys -

Internal mounted - intended to go on the side or inside of a house, building etc (as seen in the pics in this thread)
http://www.geekzone.co.nz/forums.asp?forumid=49&topicid=136718

and

Extenal mounted - intended to go on poles, on fences, in pits or even directly buried in the ground (as seen on a pole in the thread)
http://www.geekzone.co.nz/forums.asp?forumid=135&topicid=114061

in many instances for the later you wouldnt know if your line was feed by one of these and it could be installed several kms back up the cable if the other line was required there.

Either way they (unlink the 1+1 feidl unit) they are powered from the exchange with + - 100v
