Embodiment Construction

[0012] Such as figure 1 In the hot backup system of a teleconference system shown, the active main control CPU, the standby main control CPU and several functional boards are connected through an IP Ethernet network. The slots of each functional single board correspond to different IP addresses, and the active main control CPU is connected to the standby main control CPU to control the client.

[0013] The system works as follows:

[0014] (1) Active state. After receiving the message, the main control CPU processes the message according to the normal process. After the successful processing (that is, after the message is successfully processed and the local memory data and related files have been modified), except for the message that does not modify the memory In addition, other programs need to be modified synchronously in the standby state. The specific messages and memory data structures that need to be synchronized and the method of synchronous modification...

Abstract

The invention discloses a hot backup system of a telephone conference system, relating to a system device on the aspect of a communication technology. The defect of low reliability exists in the prior art. The hot backup system comprises a communication network as well as a main master control CPU (Central Processing Unit) and a standby master control CPU which are connected through the communication network; the system also comprises a plurality of functional veneers which are also connected with the main master control CPU and the standby master control CPU through the communication network. The reliability and the stability of the system are improved, and the system is convenient to use.

Description

technical field [0001] The invention relates to system equipment in communication technology, in particular to a hot backup system for a conference call system. Background technique [0002] Existing multi-party telephone conference equipment based on CPCI platform, its telephone switching and multi-party conference functions are carried out through the Hll0 bus, and there is only one control CPU in the system. When the components of the system, especially the CPCI main control CPU, fail, the entire system will Will be paralyzed, the reliability of operation is low, and it is not easy to popularize and use. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a hot backup system for a teleconferencing system, which enhances system reliability and is easy to use by setting up two main control CPUs in the system. [0004] For this reason, the present invention adopts the following technical ...
