Does anyone know of a source for RJ11 module sockets similar to the
RJ45 module sockets sold by TLC? These are about 50mm x 25mm & click
into a face plate which in turn goes onto a standard 85mm square
mounting box? [ie similar style to TLC catalog page 224 item no
CX-402R.]

You can plug an RJ11 into an RJ45 socket.
