AI Technical Summary

Problems solved by technology

In this way, the impedance model of the user line does not match the impedance model of the terminal equipment, so that in the case of a bad line environment, the rate will be low, and even the service will fail, which seriously affects the quality of data services.

Embodiment Construction

[0031] In the embodiment of the present invention, multiple impedance models are configured in the VoIP gateway. The VoIP gateway determines the type of the connected device according to the connection signal sent by the connected device, and then determines the corresponding impedance model of the connected device, and then the VoIP gateway switches to the impedance model, thereby ensuring Matched user line impedance characteristics improve line quality.

[0032] see figure 1 , the main method flow of line connection in this embodiment is as follows:

[0033] Step 101: The VoIP gateway determines the type of the connected device according to the connection signal sent by the connected device. The connection signal is a signal tone or the like. Different types of connected devices have different connection signals.

[0034] Step 102: The VoIP gateway determines the corresponding impedance model according to the type of the connected device.

[0035] Step 103: VoIP gateway ...

Abstract

The invention discloses a line connection method for improving transmission performance, which comprises the following steps that: a VoIP (Voice over Internet Protocol) gateway determines the type of a connection device in accordance with a connection signal transmitted by the connection device; the VoIP gateway determines a corresponding impedance model in accordance with the type of the connection device; the VoIP gateway judges whether the current impedance model is the determined one, and switches the current impedance model to the determined one if not; and the VoIP gateway connects the connection device to a transmission channel corresponding to the type of the connection device. The invention also discloses a device for implementing the method.

Description

technical field [0001] The invention relates to the communication field, in particular to a line connection method and device. Background technique [0002] VoIP (Voice over Internet Protocol, VoIP) digitizes the analog voice signal (Voice) and transmits it in real time on the Internet Protocol (IP) data network (IP Network) in the form of data packets (Data Packet). The biggest advantage of VoIP is that it can widely adopt the environment of Internet and global IP interconnection, and provide more and better services than traditional services. VoIP can cheaply transmit voice, fax, video, and data services on IP networks, such as unified messaging, virtual phone, virtual voice / fax mailbox, directory service, Internet call center, Internet call management, video conference, e-commerce , Fax storage and forwarding and storage and forwarding of various information, etc. [0003] In China, the impedance model of the telephone terminal equipment complies with the Chinese three-...
