The motherboard supports the 3Com Virtual Cable Tester (VCT)
technology. The VCT virtually diagnoses and reports cable faults using the
Time Domain Reflectometry (TDR) tool. The VCT technology detects and
reports open and shorted cables with up to 1 meter of accuracy. It also
detects impedance mismatches, pair swaps, pair polarity problems, and
pair skew problems of up to 64ns.
VCT remarkably reduces networking and support costs complementing a
highly manageable and controlled network system. This tool can be
incorporated in the network systems software making it ideal for field
support as well as development diagnostics.
The 3Com Virtual Cable Tester requires using Windows 2000/XP
operating system.
