Cabletron also used to use this type of connecttion. Obviously the previously mentioned Ortronics part, but I believe Leviton and Siemons also a similar part. Would be suprised if they still do, but not sure.
Not going to say that there are not Cat5e, but I've only ever seen Cat5. I think we've still got one or two lying around some where (we used to be all Cabletron). I'll try and hunt them down and see what they are.
