Definitions

  • communications devices can be used for switching, cross-connecting, and interconnecting communications signal transmission paths in a communications network. Some such communications devices are installed in one or more equipment racks to permit organized, high-density installations to be achieved in limited space available for equipment.
  • Communications devices can be organized into communications networks, which typically include numerous logical communication links between various items of equipment. Often a single logical communication link is implemented using several pieces of physical communication media.
  • a logical communication link between a computer and an inter-networking device such as a hub or router can be implemented as follows. A first cable connects the computer to a jack mounted in a wall. A second cable connects the wall-mounted jack to a port of a patch panel, and a third cable connects the inter-networking device to another port of a patch panel. A "patch cord" cross connects the two together.
  • a single logical communication link is often implemented using several segments of physical communication media.
  • NMS Network management systems
  • NMS systems are typically aware of logical communication links that exist in a communications network, but typically do not have information about the specific physical layer media (e.g., the communications devices, cables, couplers, etc.) that are used to implement the logical communication links. Indeed, NMS systems typically do not have the ability to display or otherwise provide information about how logical communication links are implemented at the physical layer level. Summary
