Abstract
A method for communicating configuration information between two interface devices connected to a communication link in a system in which each device is capable of generating and recognizing an alarm indication signal (AIS) indicating that the device generating the AIS is not available for communication. In a communication system utilizing the present invention, each interface device is capable of modulating the AIS signal and recognizing a modulated AIS signal. A first modulation pattern is used to establish communication between devices with incompatible configurations. Configuration information is then sent from one of the devices by utilizing a second modulation pattern.
