    Abstract: A programmable multi-function telecommunications device starts a timer when it detects a first signaling signal, such as a test signal, on a communication channel. If a second signaling signal, such as a ring signal, is detected during a predetermined time period measured by the timer, the information following the ring signal is automatically used for a maintenance function or for program memory upgrade. If the ring signal is not detected during the predetermined time period, the information following the ring signal is provided to the equipment's user interface in a conventional fashion.
