Abstract
A facility management system including facility control devices, monitoring arrangements, and actuating arrangements is provided. Each facility control device is connected to every other facility control device through a group of Integrated System Digital Network (ISDN) bearer channels (B-channels). Each facility control device is further connected to every actuating and monitoring arrangement through an ISDN data channel (D-channel). This facility management system allows each facility control device to communicate with all other facility control devices without any intervening communication processing by other facility control devices. Thus, this system does not create the throughput bottlenecks and reliability problems inherent in systems which necessitate such intervention. The components of this facility management system are networked over telephone lines, thus, the system does not require the installation of separate network lines between each system component.
