I installed a CNT 2700 at my previous employer's data center. I'm now with another company and looking for a much smaller switch. Does anyone know of a matrix switch that will support the following criteria:

6 DS-3's and 12 T-1's terminated across 7 Routers. It needs the ability to move any circuit to any router (in case a router fails). It needs to be passive or redundant in some form so that if it loses power, etc it will not take down the WAN circuits. It also needs monitor/test ports to connect analyzer/test equipment to and be able to insert them in circuits with no interruption. Ant help is appreciated. Thanks!
