Re: Odd broadband behaviour.

Thanks Keith ,

I tried as you described and yes it’s still crackling. This is a new 5C socket that was fitted on 15th Jan when I first reported this problem of varying speeds .

I called BT earlier today and have got an engineer coming out on Monday afternoon so hopefully I’ll be able to convince him it’s the line as I said before .

It amazes me - moving from SE England where I’d wait up to 2/3weeks , to Scotland  where they do a near next day service .

In Jan they fitted this new master socket and checked all socket wiring ( 3 further sockets)  , and  removed one of these socket from use ( by crimping cables together behind it).  He said he was getting a “too many sockets Reading” I only have 4 including the master , only two were in use.

I would have thought he’d have tested for noise , but perhaps it’s intermittent.

Thanks for your help , I let you know Monday how it goes.

Re: Odd broadband behaviour.

If you are using the 5C, then you really need the Mk4 VDSL filter to isolate the other sockets from the broadband signal, as they will affect the speed, even if there is just the wiring connected.

This document explains it all.

Re: Odd broadband behaviour.

Hi ,

 

Thanks for this , I’d read about this but thought using filters in each socket would be OK?

the house originally had a talk talk filtered socket in the cloakroom , but the hub wouldn’t connect when plugged into  to any other socket, so the previous owner change it to a non filter one. Then BT engineer in Jan changed it to this 5C.

 

I’m off under the floor today to see how it’s all connected to the other 3 sockets as in the engineers last visit he said he couldn’t check this as they are not allowed under floors.

 

The master socket 5c is located in the cloakroom,n  of all places , so nothing connected to it at all.

One socket in the Office where I have the HH6  off a  dongle filter with a digital phone on the filter too

One socket in hallway not connected , just two cables ( 3 connections)  crimped behind it.

One  socket in master bedroom with filter and analogue  phone will connected there.

 

If I changed the master socket to a VDSL, to separate from phone cct,  do I then run the data connection ( red connector in your picture) to the office extension , if so what type of socket do I then fit in the office to take the phone and HH6. Or do I have two sockets in there?

 

many thanks

Re: Odd broadband behaviour.

Sounds like you have "star" wiring, this will impact on your broadband connection because of the extra wiring in parallel with the main incoming line.

All extension wiring must come from the extension terminal block on the 5C master socket, as described in that document.

With a filter plate fitted, the home hub must be connected to the DSL output on that filter plate.

If you need the home hub elsewhere, then you need to run a separate single pair cable from the data extension terminals on the MK4 filter, and then a separate pair of wires for the phone.

If you have a two or four pair cable going to the location of the home hub, then you can use two separate pairs.

You can get a separate RJ11 socket if you wish, to connect the home hub to.

As your master 5C  "test" socket is not isolating the extensions, then is possible the noise is being caused by your internal wiring, and you could be charged.

Re: Odd broadband behaviour.

Hi

 

When I remove the front plate of the 5C all house ccts are dead.

Under the floor shows the issues though 😳

Re: Odd broadband behaviour.

Could you clarify a couple of things @Keith_Beddoe ?

"All extension wiring must come from the extension terminal block on the 5C master socket"

Shouldn't extensions be daisy chained? If you took, say 3 wires, from that terminal block to 3 extensions wouldn't that be star wiring?

"If you need the home hub elsewhere, then you need to run a separate single pair cable from the data extension terminals on the MK4 filter, and then a separate pair of wires for the phone."

As the filtered faceplate filters out the data signal from the phone line. Where is the phone line filtered ot of the data signal? Surely the data line still contains the phone signal? It should only reqire a filtered faceplate  at the end of the data line.

@Barnsh14  That spur for the office is star wiring and will impact your internet.

So are the extensions connected to the terminal block underneath the front section, as they should be? If so, then the noise has to be external.

If that is the case, then I would fit a filtered faceplate, then run a single pair data extension cable from the terminals on the filter, and run it to the location of the home hub.

I assume you cannot connect the home hub to the master socket?

Re: Odd broadband behaviour.

So to fix this I can :

For phones:

remove bodge taped cables completely.

Fit the correct VDSL face place in the cloakroom

connect existing hall phone cable to VDSL

Run news cable from hall ext socket to office

Reconnect the socket in the hall that was disconnected by BT

run a new cable from office to master bedroom

All phones are then daisy chained.

 

For data

Run cable from master socket (red )to RJ11 in office

 

However is there such a thing as a front plate for the office that can take a phone and separate  data connection instead of fitting two separate boxes?

Re: Odd broadband behaviour.

Yep the home hub in the cloakroom ( toilet) is useless
So all the cctv computer , switch etc is in the office ( spare room)

Re: Odd broadband behaviour.

Hall phone would need to connect to phone socket on the front of the filter, or to existing terminals.

Other non-broadband connections (extensions) would stay connected to existing block behind faceplate.  Once you fit the filter plate, this block would become filtered so no broadband will go out on the extensions.

Finally, a single pair of wires from the data connections from the red terminals, to the location of the home hub.

You can get double outlet wall sockets similar to this, from electrical suppliers. One is a normal phone socket, and the other is an RJ11 socket.  They are sometimes supplied as modules that just fit into a cutout.

Look on CES electrical or CPC websites.
