I'm looking at 2950-LRE for a rural network. Cisco claim operation at 15Mbps at up to 5,000 ft. Does this mean you can run longer distances, above 5,000 ft., at lower speed? I'd like to use a single switch to serve both short and long loop customers, up to 12,000 ft. If not, I'll need G.SHDSL I guess. Aled
