Topic # 138428 3-Jan-2014 16:50 Send private message

I want to use my Linksys PAP2T with my existing structure cabling, and am thus looking for some RJ11 to RJ45 cables, any suggestions on where to find these? (aka plug existing analogue cordless phone into RJ45 socket in the lounge and keep the PAP2T in the cupboard with the router and switch etc)

Will the RJ12 to RJ45 cables from Cables Direct be suitable?

Thanks

Yep RJ12 will be fine. Just has the extra two pins the RJ11 is missing.

Just to help with visualising the pinouts on the RJ Plugs (wired with ribbon cable for voice use)
here is a little pic

The Handset cord plug is also reffered to as RJ10

The discription after the name reffers to the number of Pins and then the number of Pins Connected

You can actually put an RJ-11 plug in an RJ 45 socket but i don't think it's recommended.

Correct as the edges of the plug push up the sprung pins in the socket, and bend them up, so when you try to then use the socket for a data outlet later you have miss connections

It will work quite happily. The problem can occur when you need to use an RJ45 back in the socket, and the outer pins are damaged.

Awesome

Does using RJ12 instead of RJ11 solve this? I've always wondered. Will a RJ12 cable fit into a device (like a phone) that is expecting a RJ11?

Yes because the positions are still there on an RJ11 just not the pins.

Yes as an RJ11 has the same basic profile as a RJ12 but the 2 outer pins are either blank (not installed) or the plug is molded without the slots - but the same dosent apply the other way around as a RJ12 socket can have the two outer spring pins damaged when a all molded RJ11 or RJ10 is inserted. Just like an RJ45 socket can be damaged with an RJ10, 11 or 12 plug inserted in them (even though it will fit)

They would be suitable. Alternatively I could make some and courier them to you. PM me the length you need for each cable and your physical delivery address for a courier.

If you are making a RJ45 --> RJ11 cable, then what is the best cable to use?

Would you use Cat 5/6 and cut off the spare pairs at the RJ11 end? Or... use a 4 core cable?

You would use a stranded flat cable. Find an old BT cable that you don't need anymore and chop the BT plug off. Need to use a "flat" RJ45 plug to hold the cable in.
