Problems solved by technology
However, this solution itself also has disadvantages: because the Codec (Coder&Decoder, codec) and the analog interface connected to the analog terminal occupy a large space, it is limited by the internal space of the VoIP gateway, and it is difficult to integrate a large number of high-density voice boards. The number of analog interfaces cannot provide support for hundreds of channels or more of analog access; at the same time, the number of analog interfaces is limited by the internal space, which also makes it difficult to fully utilize the processing resources of the VoIP gateway, and the composition is relatively high; In particular, the analog interface type of the VoIP gateway is often fixed, so when the interface type needs to be changed, only the replacement of the VoIP gateway can continue to provide VoIP services, and the flexibility and adaptability are very poor.

Embodiment Construction
[0027] Specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described here are for illustration only, and are not intended to limit the present invention.
[0028] The technical idea of the present invention is to use external analog access accessories to realize the access of the VoIP gateway to the analog signal, that is, to connect the functional chips such as the Codec and the analog interface, which occupy space, to the VoIP gateway through an external method, so as to achieve no Limited by the purpose of the space of the VoIP gateway itself, it is easy to expand the analog access to make full use of the processing capacity of the VoIP gateway, and it is easy to adjust the analog interface at low cost and flexibly by replacing the analog access accessories.
[0029] First, the embodiment of the present invention provides a component 100 for implementing analog access of a VoIP gateway, which is suitable...

The invention discloses an assembly for realizing the VoIP gateway analogue switch-in, a VoIP gateway and a process for realizing the VoIP gateway analogue switch-in. The process comprises initializing the VoIP gateway execution hardware resource, identifying the type and the number of an external analogue interface and conducting the switch-in adaption, and realizing the switch-in control between the IP network and the analogue terminal based on the external analogue interface and the analogue / digital conversion. The number of the analogue interface can not be limited by the hardware space of the VoIP gateway through the invention, and the support for the VoIP with high capacity analogue switch-in can be provided, the relative analogue switch-in component can be changed according to the actual demand, thereby flexibly changing the interface property to suit to the different demands of users.
Description
technical field [0001] The invention relates to the technical field of VoIP (Voice over IP, voice over IP), in particular to a component and a method for realizing analog access of a VoIP gateway, and a VoIP gateway. Background technique [0002] VoIP gateways, including voice gateways (Voice Gateway, referred to as VG) and routers that provide voice IP access functions, are important analog access devices in VoIP solutions, used to connect directly or indirectly from analog terminals, including telephones, faxes, etc. The analog data received by the terminal is transmitted to the IP network after real-time compression and protocol conversion, so as to realize the transmission of traditional analog signals on the IP network; among them, the VoIP gateway generally uses the standard analog telephone interface FXS (Foreign eXchange Station, external exchange station ) to receive analog data directly from the analog terminal, through the standard analog trunk interface FXO (Fore...
