RJ11 and British phone sockets with wallplates often face problems.
RJ11 and British phone sockets with wallplates often face problems.
The standard in my country uses the British phone socket, which also works for VDSL internet. There are filters that combine a British male plug and a normal RJ11 connector for routers, plus a female British socket for phones. After modifying the wall, the British keystone no longer fits. The infrastructure connection only provides one pair of wires, originally for phone use. Could I use an RJ11 adapter to bridge it to the British socket, or should I switch everything to RJ11? Or is a full conversion to RJ11 the best option?
It’s unclear what “keystone” refers to here. I assumed it was a building-related term. Edited June 16, 2022 by Bombastinator
I think the BT connector and RJ11 port in these devices typically pass signals straight through without filtering. Using an RJ11 one-way splitter lets you connect it to the existing filter via the modem/router interface, then plug the phone in as usual. I tried this with a landline into a 5G router—it didn’t work for that service, but a tone indicated it was available. There are also options with an RJ11 input and detachable BT plug, so US filters should generally match those designs.
This connector uses just two wires in a different plug type. I’m checking if swapping it for an RJ11 socket would work without problems. It’s possible the design helps reduce noise, but I should confirm compatibility. If you replace the old British plug with an RJ11 socket, you might need an adapter—like the one listed—to connect the filter properly.
In short, I’m switching to an RJ11 socket and linking it with an adapter. Here’s how:
- Purchase the RJ11 adapter from Amazon: https://www.amazon.com/Monoprice-RJ-11-T...B005E2Y5C8
- Connect the adapter’s wires to the British socket via the adapter.
- Use the filter adapter from Amazon: https://www.amazon.co.uk/LINDY-VDSL-ADSL...068&sr=8-3
You can also find UK options that let you strip out the BT plug and swap it for an RJ11 to RJ11 connection, though they’re not as widely used now.
You checked eBay and found something that seemed available, but you're concerned about potential shipping problems.
I noticed that link you shared. It appears to be a product page for an RJ11 plug.
Consider using a pre-filtered faceplate instead of the original. This option is available on Amazon and offers additional protection.
