Abstract: A system for identifying a subscriber includes an access server coupled to a number of subscribers using a first communication network and further coupled to a second communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the first communication network. The memory stores path information that identifies a virtual circuit assigned to the particular subscriber. The processor identifies the particular subscriber for connection to the second communication network based upon the path information and the particular virtual circuit used to receive the communication from the particular subscriber.

Abstract: A system for controlling at least one camera by enabling a forward channel and a reverse channel is provided. The system includes (i) one or more cameras, (ii) a CMRS that obtains audio information, and video information from the cameras via a coaxial cable or over air. A camera control unit multiplexes PTZ information associated with the one or more cameras and generates a data packet. A modulator modulates the data packet to obtain a modulated data packet which is up converted to a desired RF frequency. A tuner receives the desired RF frequency through the coaxial cable or air, and down converts the RF frequency to obtain the modulated data packet. A demodulator demodulates the modulated data packet to obtain the data packet. A processor de-multiplexes the data packet to obtain the PTZ information that includes a command for at least one of panning, tilting, and zooming a camera.
