RJ11 to RJ45 connector

I need to move my ADSL router to somewhere discreet as the wife doesn't want it in the hallway next to the telephone which is located near the BT master socket and a pair of RJ45 sockets carrying cat5e cable. One option I've considered is to connect the ADSL cable from the microfilter into one of the RJ45 sockets (cat5e cabled) and then at the other end, connect the cable to my ADSL routers WAN socket. I'd need RJ11 to RJ45 convertor cables such as this or one of these (but which one?) at either end of the connection.

That's the theory, but would it work in practice as a way of distributing broadband around the rest of the network? Are there any risks and/or pitfalls with this approach?

TIA

rj11 plug will fit in rj45 socket so that is an easy option rather than try to find convertor cables, just make sure all 4 pairs are wired on rj45 as when rj1/adsl is connected in that way it uses pins 4/5 on rj45 cable

As Anon says, RJ11 fits RJ45 so you just need to plug in an RJ11 lead from the microfilter to the RJ45 socket and then another lead at the other location to connect to the router.

watch out for your second option somewhere in the distant past I sure I remember these been confiqured difernt for diferent patchs back at the main pannel

Thanks for the feedback guys

I might just make my own cables with the solid core cat5e that I have left over.

I've read elsewhere that plugging an RJ11 plug into an RJ45 socket can possibly damage the socket

Load of tosh about damaging the socket, they are the same modular family.

Just make sure the RJ11 plugs are for solid core cable, most are not, would prolly be a better option to get premade leads if you don't have them already.

Exactly, and I believe they were actually designed that way specifically to allow 4 way plugs into 4, 6 and 8 way sockets and 6 way plugs into 6 and 8 way sockets. Many years back I came across an 8 way plug and socket with an offset key which also allow the four easy to plug in but to connect to teh four contact on one side.

MMJ they were called IIRC, a favourite of DEC terminals

A bit of google research backed up with advice from an experienced professional does suggest that plugging an RJ11 plug into an RJ45 socket will bend the connecting pins excessively, possibly damaging the socket.

Can you provide a link?

Sorry but that's rubbish, been dealing with that stuff for longer than I care to mention.
As I said they are the same modular family and so compatibility is the name of the game. Variations between manufacturers are the only issues I've ever come across.

Your "experienced professional" probably does not know his ass from his elbow either. He is talking rubbish. as I and others have said, RJ45 and RJ11 are from the same family and were designed to allow smaller connector to be inserted into the larger sockets. I've been using them for too long - probably since the early 80s and have never heard such a ridiculous claim.

If I am not mistaken you can actually stick a flat head into the port and completely push the pins down till they lie flat with the plastic surrounding and they will still bounce back to their original position. Therefore no way an RJ11 will damage the pins.
