What is a 5C socket, and why do I have two other “primary” sockets in my basement flat?

Go to solution

Hi all

I am helping my mum renovate her flat. There are a few OpenReach sockets and we are trying to understand the role of each one…

1)

We have a master socket labelled 5C. This has only a phone line. Am I correct in saying we will use a microfilter to split this and provide an internet port?

We also have an unlabelled socket on the other side of the room, with phone line and Ethernet.

Then there is a third socket unlabelled, closest to the main road, with only a phone line.

 

Presuming we use a microfilter on the master socket - can we just get rid of the other two sockets? They are faded yellow plastic and we have no use for a phone line in those two locations.

 

2)

Following on from this, what reason would there be for three separate OpenReach sockets? The “flat” is more of a large studio with 1 bedroom and 1 kitchen/lounge area. My urge is to remove the surplus boxes but I wonder why they would be there in the first place?

 

3)

Separately to this, does a 5C socket only support Fibre (rather than Full Fibre). (Ultrafast Fibre is not available in our area yet).

Thank you.

The master socket should b the first point where the external wiring enters the property & marks the boundary of responsibility. So everything up to & including the master socket is the responsibility of Openreach & everything after, that of the resident. There should only be one per property unless there are multiple lines.

So you need to ascertain where the wiring comes in & to which socket. If in a convenient location, that can be made the master if it isn't already with a filtered faceplate, & the extra sockets removed.

Maybe have a search of YouTube for master socket wiring.

Full Fibre uses completely different technology which will render the master socket obsolete when it's available.

The master socket should be the first socket the ‘line’ from outside goes to first , there should only be one master socket , potentially someone has provided another master socket as an extension socket .

If the master socket doesn’t have a phone port and a ‘broadband’ port , that’s what plug in filters were used for , so that there was a place for the phone cord and the router cord …if the ‘master’ socket is in the best location but doesn’t have a broadband outlet, simply get a plug in filter …if you only need one socket , the cabling from the genuine master socket ( the first in line ) can be disconnected from the other sockets .

When FTTP becomes available and purchased, all the existing sockets become redundant, and a powered ONT is provided, that’s what the router connects to .
