ABSTRACT:
Apparatus and methods that allow detection and authentication of multiple devices within a subscriber dwelling. A system is described generally comprising multiple devices, each adapted to receive a broadband signal and including a modem coupled to a telephone line. At least one of the devices is configured to receive entitlement information corresponding to the other devices via the broadband signal, and to use the entitlement information to periodically authenticate the other devices via the telephone line. Several methods are disclosed for detecting a device connected to a telephone line. A described method for authenticating a device connected to a telephone line includes receiving entitlement information corresponding to each of the devices via a broadband signal, and using the entitlement information to authenticate each of the devices via the telephone line.
