Expandable broad band terminal cut-in device and its method for cut-in network

Abstract

This invention relates to an extendible broadband terminal access device and method. The basic access unit is connected with the extended unit via a bus connection unit, so that the service function can be expanded more flexibly. End users can increase related extended units freely according to the needs to ensure the end user to realize new service function. The original terminal cut-in devices can still be used effectively between broadband network and end users to reduce the cost. Besides, the basic cut-in unit is connected with the extended unit by USB interface line.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an expandable broadband terminal access device and a method for accessing the network. Background technique [0002] In a broadband network, user access to the broadband network needs to be realized through a terminal access device. The terminal access device is used to process the corresponding service data in the broadband network into service data identifiable by the user and send it to the user. For example, users of XDSL (Diverse Digital Subscriber Line) must access the broadband network through a Modem (modem) to ensure the normal development of services. [0003] Existing ordinary Modem usually only realizes the modulation and demodulation of a single signal and the processing function of related network access protocols, that is, generally only provides a function for users to access the broadband network, ensuring that end users can realize the most Basic ...

Problems solved by technology

[0005] One is to replace the original Modem with a new Modem that can realize new business functions, that is, the new Modem not only includes the functions that the original Modem needs to realize, but also includes the new business functions that need to be realized, so that end users Just can utilize this new Modem to realize corresponding new service function in broadband network; The cost of implementing new business functions increases;

[0006] Another method is to design a terminal access device that only includes the new service functions that need to be realized. By adding a new terminal access device between the broadband network and the end user, it is ensured that the end user can carry out services in the broadband network. For new service functions, the new terminal access device is interconnected with the original terminal access device (ie, the original Modem) and the broadband network only through the corresponding network port. For example, adding WLAN access function to the broadband network At the same time, you can add an AP (access point) device. The AP device is interconnected with the original terminal access device and the broadband network through the network port. The interconnection through the network port makes it inflexible on the original terminal access device. In this way, the AP device and the original terminal access device are still two independent network devices, and when they are managed, they are also independently managed. Therefore, the network is greatly increased. Complexity of device management
