Patent ID: 8385327

Claim:
An access system, comprising a broadband service interface module provided with a broadband service interface, a narrowband service interface module provided with a narrowband service interface, and a main control switching interface module, wherein: the main control switching interface module comprises a broadband service switching module that is provided with a broadband uplink interface, and a narrowband service processing module that is provided with a narrowband uplink interface and performs a narrowband service data process; the broadband service switching module is connected to the broadband service interface module through broadband buses, adapted to process broadband service data and communicate with a network via the broadband uplink interface; and the broadband service switching module is connected to the narrowband service interface module through the broadband buses, where the narrowband service interface module is adapted to process narrowband service data and is adapted to communicate with the network via the broadband uplink interface of the broadband service switching module or to communicate with the network via the narrowband uplink interface of the narrowband service processing module; wherein the narrowband service interface module comprises: a voice service packet processing module, adapted to perform a voice service packet process or a voice service de-packet process on the narrowband service data; and a circuit emulation service (CES) packet processing module, adapted to perform a circuit emulation service data packet process or a circuit emulation service data de-packet process on the narrowband service data.
