Following on from a previous post. I have done more research on the cabling mess that exists under my house. I have uploaded an image here.

Essentially the household cabling enters the house (with no ETP box). It is then patched to the alarm and then a jumpled mess of connections to a number 2 and 3 wire BT ports in the house.

I am quite keen to put in a proper patch panel, remove the alarm connection (without setting of the tamper alarm - wife not happy when this happens

) and put in only two 2 wire ports in the bedroom (DSL) and kitchen (phone). The BT ports are a mixture of M (master), S (secondary), E (extension) and 2 (i assume some form of extension). I will not install a master splitter at this stage.

I have had a look through SBiddle's posts on household wiring and quite interested in the idea of a using a standard patch panel to wire in the incoming connections to the two BT boxes. I will also install a test point first to comply with any standards.

Any hints or comments are appreciated. I would like to stay within the realms of the current wiring standard also.

Thanks

Grant

Sounds like a good plan of attack - I'd also suggest shortening the wires where possible by having a look whether a wire does a whole loop of the house when a straight line would be alot more efficient. In my parents house I rewired there is a connection that went from one room to another room then to the main telephone then up stares - around 10metres or so was added on that simply wasn't required. The problem was made worse with the slicing and dicing that both Telecom and TelstraClear had done in the past. One fixed up the line quality in terms talking and hearing was vastly improved.

IIRC, the alarm has to do through a filter as well, from what I have heard that can cause ADSL issues.

Thats not really a mess, its all in one place and seems quite easy to get to.

IMO, do it right once, get the filter, put it between the entry cable and the feed to the alarm. IME with alarms, tamper only goes off if its set and you cut the phone cable, if its not set the keypad just beeps at you.

One of those cables (rear lounge) looks to be the flexible flat stuff which wont scotchloc properly, so leave it off if you dont need it.

standardize on blue and white for pots and orange and white for the DSL, since thats what it normally is on cat-x cables, and replace the jacks with 2 wire ones all round.

Or pay the ISP/telecom to have chorus come and do it for you, but I dont know what they will do with that non suitable cable you have.

I have disconnected the existing lounge connections to remove some of the confususion regarding the wiring. The next step will be to replace the existing 3-wire installations with 2-wire ones.

With regards to the required test point, It this a special jackpoint or just a standard 2-wire jackpoint? I was thinking of reusing one the redundant jackpoints from the lounge, although it does not appear to have the required resistor for Telecom line testing. Also, can this be placed under the house (suspended floor) where the old splicing was located?

Other than that it would seem to be a fairly straight forward process of connecting two new 2-wire jackpoints (removing alarm wiring) and all should be done.

Hi, dont worry about a test point unless you intend to implement a complete structred wiring setup, if all you want to do is replace the 3wire with 2wire and remove unwanted wiring then you dont need a test point. I would simply add replace the sockets with 2wire ones, also install a central filter and with the line going to the bedroom(DSL) carrying both DSL and phone to that room, put the phone on red/white and DSL on Blue/Green. Alternatively (and if it were my place) replace that entire run from this wiring hub to the bedroom with a new cat5e run, blue pair carrying the phone, orange the DSL, use a two mech plate, one with a BT for phone and one with a RJ45 to provide the DSL (orange).

From here any additions to house wiring should be cat5e with RJ45s for ethernet carriage, once again if the phone and ethernet is not fully structured (ie not carrying phone on same cabling) then no need for a test point.

Also the test cap/resistor network is only needed if you pay Telecom for a house wiring contract, I suggest you dont and therefore Telecom wont ever test for the test network.

I have my master filter and a collection of scotchloc's. I have decided to throw this in at the start, wire a new Cat5 cable to a dedicated ADSL jack and ignore the rest of the telehone cabling for the moment.

I have read somewhere that the incoming line is not polarity sensitive, is this correct?

Hi, yes for all intense and purpose dont get hung up on polarity, all devices including DSL are polarity insensitive. As a matter of course Telcos attempt to maintain polarity through the copper network, but only to maintain consistency and avoid confusion, the reality is it makes no diff.
