Connecting to the master socket

Hi
My BT master socket has an external RJ 9 socket and an internal single pair connector.

Using the internal connector would look neater, but which is better to connect my openreach modem to ?

Thanks

What is an RJ9 connector ?

I think he means RJ45

Think I should have said rj11

My Bt Openreach Nte5a Master Socket has an RJ45 socket at the top and a BS6312 431A phone socket at the bottom.

I plug the modem lead RJ11 plug into the top RJ45 socket and don't use the internal connector as that would involve a krone tool.

Using a Krone tool isn't an issue.

Just wondering if either connector would give a better connection.
I'll try internal to start and see how I get on.

Use the RJ45 connector.

The modem will have an RJ input which will need a connector and associated lead. The lead will be multi-stranded cables and NOT suitable for connection to an IDC.

My master socket has one RJ11 and one BT Connector.
On the inside there is a Krone strip for a single pair.

I've made a cable that connects from the openreach modem and connects to the single pair connector.
(the cable is solid and not stranded)

Only reason to do this was to move the openreach modem nearer the master and plug it in to a mains socket on a different circuit to the main house.

My pfSense router has detected the connection and reconnected without issue.

Thanks

Will make no difference to the connection as to whether you use the unfiltered IDC or unfiltered RJ45 socket

Solid wire is generally unsuitable for connecting to an RJ11 plug for the modem.
