Till recently, there was no specific way to figure out a broken link on a near real time basis. With the advent of Intelligent cabling, this problem seems to be getting resolved. In an intelligent network setup, the systems can automatically find out devices connected with the physical layer and can link them with connectivity changes, and also track device locations. Essentially in an intelligent cabling setup, the specialized ports, patch panels and outlets work like sensors and can be managed through a software over SN M P or some other similar protocol.
So in an intelligent cabling setup, you are essentially SNMP enabling the physical layer devices. With intelligent cabling, a person can get a logical view of the entire network.
Such cabling also enables automated and secure documentation of the network layer. It provides security as it can identify unauthorized modifications on a real-time basis and can generate alerts automatically. Some prominent players in intelligent cabling in India are Digi-Link (through RiT), Panduit, Tyco, etc.
