Virtual Cable Tester™ (VCT)
Technology
The P4P8X 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 have 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.
