Topic # 113750 27-Jan-2013 00:10 Send private message

A newish flat with this patch panel installed. CAT5E to all rooms.
However theres an issue with DSL sync. With every port except the one its plugged into, labelled a RJ35X port (for home alarms?), it gets 2.5 megabit sync rate. This includes every port around the house and the port below the one its currently plugged into.

On the RJ35X port it gets 5.6 megabit sync rate.




Houses up the street get 11 megabit. But of more interest is the twin flat which is 90% identical to this one and the second half of the building, gets 8.1 megabit sync rate at 36 db and 10 SNR.
This one is
2.5 megabit at 35 db and 12 snr
on the RJ35X its
5.6 megabit at 36.5 db and 12 snr
or when tweaked
7.9 megabit at 36.5 db and 7.8 snr

I'm confused as to why it has to be plugged into the RJ35X port which appears to be for an alarm. Why can the neighbours in a near identical place plug theres into the lounge, so not even in at the patch panel, and get a far higher line speed?

Tried with two modems. Same result.

I don't see an xDSL splitter in those photos.
Do you know where this is located?
Is there even one installed?

Normally you would only get an xDSL signal on one port in the patch panel and if you want it on another port somewhere in the house/flat you would need to patch it through.
You shouldn't be getting the xDSL signal on all ports without doing any of that.

As far as i know there is no central splitter unless its wired in behind it. No patching going on here.

Yeah that's how i'd install it too.

And no line filters are in use of course because its Naked DSL. The adapter you can see in there is simply to allow the BT to plug to RJ45. Its from DSE and has a telepermit.

Naked DSL doesn't remove the need for a master filter if multiple jackpoints are used.

My pick would be dodgy wiring to one of the 4 jackpoints. The way to test this is to remove the blue pair on each of these and see what speed you get.

As expected by many installers who have no idea what they're doing, this patch panel wasn't actually installed in the way it was designed to be used.

So I take it in each room there is one Rj45 which comes back to the lower panel and one BT portthat goes to the top panel, if so that is daft and not as desired under the TCF.

Remove the blue pair from the very left input side of the phone panel, connect it to a single socket, there are spares on the lower panel and connect your modem there

I would also terminate the current phone circuits on the spare lower panel, replace the room BT's with RJ45s and forget the voice panel. Alternatively replace both panels with a ST2208 which has 8 data ports, 4 rj45 voice patching ports and IDC,s to terminate a central filter on, alternatively it can be easily rejigged to take an ata an allow it for patching.

Its two rj45 to each room. One voice to the top panel, one data to the bottom panel.

Will the phone line be coming in on the blue pair?

I tried to find the termination point outside but it must be in the house somewhere because there's nothing visible.

As has already been commented on - the top connection pannel is the the wrong one to the used with rj45s as the outlets

In saying that, if the rj45 outllets were to be dedicated to only ever be for phone (hard wired and not patchable) then what the ##### who installed it has done is to wire it up completly wrong. Only one pr (pair) is terminated on the panel per outlet ( the blue pr). The other prs are not used and should not be terminated (on either end)

This pr from the outlet gets terminated on to the panel on the corresponding line number that it is to be dedicated to 1,2,3 or 4 (depending on the number of incoming lines)

The RJ45 jacks on the pannel are wired across all 4 lines so that they can be used to patched across to a second panel of the same type.

I suspect the phone line comes in on what is the first connection block on the panel, on the blue pair

Whoever installed this should be prevented from ever installing data kit again because it's a complete disaster,

The correct setup is to run every RJ45 jackpoint in the house to the bottom RJ45 patch panel (which would have required a bigger module in this case). 110<->RJ45 clip on adapters are then utilised on the top phone distribution module to patchphones as required to the ports on the bottom patch panel.

As it stands now phone jacks around the home can only ever be used for phone, when they should be dual use.

The IDC terminations are 110 type - if you pull off the wrong one and need to put it back or you deside to reconfigure the terminations as below


Naked DSL - deside which outlet the modem/router is going to be connected to and unterminate all the others and just leave the blue pr for that outlet connected (or none if your goingt o use the jack on the panel) . Terminate all the prs of the removed cables on the to spare blocks on the bottom block


Not Naked DSL - a Spliter can be terminated on the pannel

1. remove all prs but the blue ones
2. terminate a spliter across the last terminal strip as follows - line in 2, phone 3, dsl 1
3. move the incoming line on the first strip from 1 to 2
4. deside which outlet you are going to connect your modem/router too them move all the blue prs, to the other outlets, from 1 to 3
This way if you deside to leave the router pluged into the jack on the pannel it will still have direct access to DSL (lke you currently have)

Yeah i thought this was a bit odd, i thought the purpose of a patch panel was for flexibility. Haven't seen many installed though, ive done a data only one myself before though.

I'd love to utilize your services, but the people in this flat i don't think can afford a professional installer (hence why im looking at it at no cost). From what ive seen on here your work is top notch.

It sounds like the easiest solution to this dodgy install is ripping out all other phone connections as suggested
