Gbe signal switch suggestions

[rfdes]

Hi -
I need some suggestions as to how to electrically disconnect differential Ethernet signals (Gbe) from a physical  connector.  Basically a high speed analog switch that can handle the bandwidth and provide adequate off isolation.  This seems like a simple in principle design task but I'm struggling to come up with an acceptable topology.  I suppose one could use an RF relay but I would rather use a semiconductor solution.  I cannot seem to find any analog switches that would provide an acceptable solution.

Any ideas would be appreciated.

It would help if we had more details as to exactly what you're trying to accomplish.

Most ethernet switch ICs and ethernet PHY ICs do have the capability to enable/disable each Ethernet interface. So why not use a switch IC?

Thanks for the responses.  Yes, I should have been more clear in my original post.  After my post, I found several parts that are designed to do what I want.  That is to simply multiplex the signals.  The Pericom PI3L110 part appears to be just what I need.  Maxim also sells several LAN mux parts MAX4890-MAX4892.  I believe this will solve my problem.
