Problems solved by technology

[0008] The data and voice transmission functions based on the ISDN network can be realized by using the above method, but for voice transmission, voice can only be transmitted through the voice channel in the 2B+D channel, if the 2B+D channel provided by the ISDN service provider does not provide voice channel, or when a voice channel is provided but cannot meet the needs of multiple users, the voice transmission is limited

Embodiment Construction

[0023] Hereinafter, the router for transmitting various data and voice services of the present invention will be described in detail with reference to FIGS. 2-3.

[0024] As shown in FIG. 2 , it is a structural diagram of a router for transmitting various data and voice services according to the present invention. The router includes: an ISDN-U interface module, a central processor module, a voice processing module and multiple interface modules.

[0025] Among them, the ISDN-U interface module is used to receive signals from the ISDN network, and separately process the 2B+D channels of ISDN, and perform advanced data link control (High-level Data Link Control, HDLC) on the data signals of the data channels. ) after processing, it is sent to the central processing unit module for processing through the universal bus interface; the voice signal of the voice channel is sent to the corresponding interface module for sending and receiving voice through the voice bus interface;

Abstract

The invention provides a route for transmitting several data and voice service, which includes: ISDN-U interface module, central processing unit module, voice processing module and several interface modules, ISDN-U interface module, the data signal in data channel is done HDLC procession and sent to the central processing unit module; central processing unit module, which is used to analyze the processed data packet, when analyze the voice IP data packet, the voice IP data packet is sent to voice processing module; voice processing module, which is used to receive the voice IP data packet sent by central processing unit module, and reverts it as the original voice data. The invention can transmit voice via ISDN-U interface module, and improve the integrated service ability in real system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a router for transmitting various data and voice services. Background technique [0002] With the development of the Internet and the continuous expansion of various communication services, routers have become more and more common in practical applications. [0003] Usually, in a practical application where a router transmits through an Integrated Service Digital Network (ISDN), data and voice can only be transmitted on the data and voice channels in 2B+D of the ISDN network. Among them, 2B+D means that two 64Kbps B channels and one 16Kbps D channel are provided in both directions on the physical path of a pair of subscriber lines, where B is the bearer channel (Bearer Channel); D is the signaling channel (Demand Channel). [0004] As shown in Figure 1, it is the application of an existing router in an ISDN network. The router has a U interface for accessing the ISDN swi...
