A fiber optic cable management system that may be provided in a bay (or shelf) of an optical communications housing. The fiber optic cable management system includes at least one and preferably several interconnecting fiber optic cable guides. Each fiber optic cable guide includes a radius limiting portion that prevents fiber optic cables from being bent beyond their minimum bend radii. The radius of the radius limiting portion of each guide controls the spacing between a specific guide and its adjacent, interconnecting fiber optic cable guides. The width and height of each fiber optic cable guide may be varied depending upon the optical communications system into which the fiber optic cable management system is utilized. The interconnecting fiber optic cable guides may be easily disconnected from each other to allow the fiber optic cable guides to be used in different quantities. This allows an installer to customize the fiber optic cable management system to match the optical communications equipment.

An alert indication signaling (AIS) device is provided. The AIS device includes a first detector that detects a first event, a line detector that detects a second event that includes an incoming call on a communication device, and a microcontroller directly connected to the first detector and the line detector. The microcontroller transmits at least one signal based on at least one of the first event and the second event. A display unit receives the at least one signal from the microcontroller. The display unit displays a visual message that indicates an occurrence of at least one of the first event and the second event based on the at least one signal. A speaker produces an audio output that corresponds to the visual message and at least one of the first event and the second event. The audio output and the visual message are concurrent.
