Virtual Cable Tester™ (VCT)
Technology
The P4P800 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.
