If you were to clarify what it is you want, or are trying to do (e.g the application), I'm sure you'll get more responses.
If by adressable you mean remotely controllable (e.g to allow remotely enabling or disabling the jack?) then you need to be more specific. Does you want to control it using Ethernet and IP?
Since an RJ-45 could be used for any number of different applications, this clarification would help.
BTW, a quick scan of the above link looks like this may be Keystone compatible. IN that case you could pair it with anything else you like (if you cannot find Keystone F connectors try L-Com).
Please fill us in and let us know what you find.
Good luck
