Telephony end user interface in an HFC access network

摘要

System (100) and method for providing power supply status indications and network-originated messages on a user device interface (104) of a user device (102) coupled to an access device (110). The access device (110) receives a supply of main power from a main power supply (204), and the access device (110) is adapted to interface with a communications network (111). A backup power supply (206) is coupled to the access device (110) and is adapted to supply backup power to the access device (110) when the supply of main power (214) fails. The backup power supply (206) provides a signal indicating a power condition of the backup power supply (206) when the supply of main power (214) fails. A processor unit (208) receives the signal and generates a backup power supply status indication in response to the signal. At least one user device (102) is coupled to the access device (110) and also is adapted to receive and/or transmit information over the communications network (111) via the access unit (110). The user device (102) receives the backup power supply status indication and the status indication is communicated to a user through a user device interface (104) coupled to the user device (102).
