Old Master Socket with junction boxes and filter

My BT Unlimited Broadband download speed is around 2.1 mbps. My neighbour, on Talk Talk, gets over 4 mbps. 

My neighbour has a new NTE5 socket, which Talk Talk arranged to have fitted. I have the arrangement shown below:

 

Master-Socket.jpg

 

I spoke to BT customer services recently to ask about upgrading the master socket, but they told me it was unlikely to make much difference to my broadband speed, and that my neighbour was probably "lying". 

 

My incoming telephone line passes through the three boxes shown before reaching the master socket. The master socket is old-style with undivided front face. The white box takes an extension cable off before the master socket, so you might say that I have two master sockets. The large box has the initials GPO on the cover, and is a "Filter Unit 15A SEC 86/1".

 

I would be grateful to hear from anyone who has experience of replacing old boxes like this. Did you find it improved your broadband speed? Did you have to pay, and if so was it expensive?

 

Many thanks.

If you have an extension sockets connected before your master socket then that is star wired and will not be helping your internet connection

 

I am sure one of the other members will post about the other sockets

Re: Old Master Socket with junction boxes and filter

Thanks for taking time to reply. You have given me a new technical term to describe my internal wiring - "Star wired".

 

Would I be correct in thinking that I do not therefore have a Master Socket and my three outlets are just "Sockets"? (They are all the same.) If so, where would BTs responsibility for the wiring end and mine begin?

 

Other replies still welcome, especially from anyone who knows what a GPO Filter Unit 15A SEO 86/1 is.

Re: Old Master Socket with junction boxes and filter

The filter unit 15A was part of the obsolete WB1400 early warning system (Handel) which was fitted in centain special places. Its no longer used, and should have been recovered as it will affect broadband services.

 

See http://www.ringbell.co.uk/ukwmo/Page213.htm

The whole lot wants removing, and the incoming line connected directly to the master socket.

 

Probably a job for Openreach.

Thanks Keith

 

looks like it's an engineer visit required and hopefully after removing your broadband will improve

Re: Old Master Socket with junction boxes and filter

Looking at the picture of the filter I don't think it is connected. There are no wires on the line in terminations.

If it was my home I would want openreach to come and remove it. There is certainly a conenction running from that mess of wires to the phone socket

There does appear to be a connection to the `Tele` terminals, which would put it across the phone wiring and affect the broadband. It needs to go.

Hi,

 

Long shot, but do you still have the Filter Unit 15A ? I need one. 

 

Thanks
