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 100 meters 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.
