The Marvell
®
Virtual Cable Tester™ (VCT) is a cable diagnostic utility that
reports LAN cable faults and shorts using the Time Domain Reflectometry
(TDR) technology. The VCT detects and reports open and shorted cables,
impedance mismatches, pair swaps, pair polarity problems, and pair skew
problems of up to 64 ns at one meter accuracy.
The VCT feature reduces networking and support costs through a highly
manageable and controlled network system. This utility can be incorporated
in the network systems sofware for ideal field support as well as
development diagnostics.
