Virtual cable testing

Virtual Cable Tester (VCT) is a cable diagnostic feature in the physical layer (PHY) used for fault detection and advanced cable performance monitoring.

VCT technology enables the diagnosis of a conductor (wire or cable) by sending a pulsed signal into the conductor, then examining the reflection of that pulse. This method of cable analysis is referred to as Time Domain Reflectometry (TDR). By examining the reflection, the Ruckus device can detect and report cable statistics such as local and remote link pair, cable length, and link status.
