摘要： A method for processing cells at a user-network interface with automatic identification of virtual circuit identifiers and a testing function is provided. The method includes distinguishing the source of the cell. When the cell is from a first source, the method tests the cell against at least one selected criteria. When at least one test determines the cell is invalid, the cell is marked. When the tests determine that the cell is valid, the method translates a virtual circuit identifier to a default setting and forwards the cell to a queue for further processing.

摘要： A system for determining the physical location of a home terminal unit senses that a cable carries a communication signal from a home terminal unit to an optical network unit. The system includes the home terminal unit, the optical network unit, and a cable that connects the home terminal unit to the optical network unit. Additionally, energy detection circuitry associates with the cable to detect the presence of a communication signal on the cable and generates a detection signal in response to detecting the energy on the cable. Status circuitry for reading the detection signal connects with the energy detection circuitry and communicates the detection signal from the energy detection circuitry to the telecommunications network.
