Virtual Cable Tester™
Technology
This motherboard supports the Marvell Virtual Cable Tester (VCT)
Technology. The VCT virtually diagnose and report cable faults using the
Time Domain Reflectometry (TDR). With this essential tool, installation
and network diagnosis has never been easier. 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. Also, this tool can be
incorporated in the network systems software making it ideal for field
support as well as development diagnostics.
