Multi-user expansion system

Abstract

This invention relates to phone and data communication system user extension method and discloses a multi-user extension system, which comprises main machine frame and second machine frame, wherein the main machine frame comprises operation board module and main control process board module and the second machine frame comprises second operation board module. The main control process board module is connected with main machine operation board module through backboard or panel of the main machine frame and is used to manage the main machine frame operation board module and second frame operation board module.

Description

Technical field [0001] The present invention relates to a user capacity expansion scheme in a telephone / data communication system, and particularly relates to a small-scale user capacity expansion scheme in a telephone / data communication system. Background technique [0002] With the development of society, the number of users demanding telephone and data services has continued to increase. According to a statistical data from the International Data Cooperation (IDC), in the world’s network business, the annual telephone business The growth rate is 10%, and the annual growth rate of data services is 40%, which requires continuous improvement in the density of communication equipment. [0003] Many telecommunications equipment are slot-type equipment. We can divide a 42U (1U=1.75 inch) high cabinet into several racks. For example, divide it into 6 racks, and the usable height of each rack is 6U. , The remaining height is the distance between each frame. Among them, the machine fra...

Problems solved by technology

[0005] In practical applications, the above solution has the following problems: using a solution based on master-slave equipment to expand user access capacity, when the number of users to be expanded is relatively small, the implementation cost is high and the management is relatively complicated, which is not conducive to the rapid entry of products into the market

[0006] One of the main reasons for this situation is that no matter how many users need to be added in existing technical solutions, they are implemented by adding physical entities. When the system only needs to add a small number of users, for example, only 1.1 physical entities are required in theory When the capacity is large, the same system structure is also required, that is, two physical entities based on master-slave device management are required to implement. Since two physical entities need to be run and master-slave device management is required, the cost of the system and management The increase in complexity is not conducive to the rapid marketization of products
