METHOD OF DETECTING A NETWORK CABLING CHANGE |
摘要 |
A system and method of detecting a network cabling change comprises measuring cable parameters of a cable to create a baseline signature of the cable and storing the baseline signature in a memory. The system and method is operable to detect a cable change based upon a comparison of the stored baseline signature and a subsequent cable measurement. A network device operable to perform the above method comprises a physical layer device that transmits signals into a coupled cable and receives return signals from the cable, a cable diagnostic module that measures cable parameters, a memory operable to store a baseline cable signature, and a controlling system that compares subsequently measured cable parameters to the baseline cable signatures to detect a cable change. |
