Narrowband speech and broadband speech combined distribution frame

Abstract

The invention relates to a communication device, particularly to a narrowband speech and broadband speech combined distribution frame. A narrowband speech input module and a narrowband speech output module comprise a plurality of narrowband input and output terminals respectively; a broadband speech input module and a broadband speech output module comprise a plurality of broadband input and output terminals respectively; a broadband speech local side device is connected with the broadband input terminals through broadband data interfaces, the broadband input terminals are connected with corresponding broadband output terminals, and the broadband output terminals are connected with a user broadband terminal through a user data interface. According to the distribution frame, the narrowband speech modules and the broadband speech modules are combined on one circuit board, a user only needs to unplug a connection line between a narrowband user terminal and the narrowband speech output terminals and connect the broadband user terminal with the broadband speech output terminals when the user needs to cutover to the broadband speech from the narrowband speech. The frame has the advantages that not only the operation is simple, jumpers are few, misoperation is avoided, but also terminals can be prevented from being occupied by ineffective jumpers.

Description

technical field [0001] The invention relates to the field of communication, in particular to a distribution frame for narrow-band voice and wide-band voice. Background technique [0002] With the development of communication technology, people's needs are getting higher and higher, and it is often necessary to cut over narrowband voice to wideband voice. The problems of the current cutover are: 1. It is necessary to jump from the narrowband terminal to the broadband terminal, and then jump from the broadband terminal to the outside line end. When the installation rate is high, due to the many and disorderly jumpers of the user, it may lead to misoperation, causing other users to interrupt unintentionally and cause communication obstacles; The wires have not been removed, and new users cannot check whether the jumper is an invalid jumper or a valid jumper due to the confusion of the jumper during installation. Therefore, it may cause a large number of terminals to be occupie...

Problems solved by technology

The problems of the current cutover are: 1. It is necessary to jump from the narrowband terminal to the broadband terminal, and then jump from the broadband terminal to the outside line end. When the installation rate is high, due to the many and disorderly jumpers of the user, it may lead to misoperation, causing other users to interrupt unintentionally and cause communication obstacles; The wires have not been dismantled, and it is impossible to check whether the jumper is an invalid jumper or a valid jumper due to the confusion of the jumper when the new user installs it. Therefore, it may cause a large number of terminals to be occupied by invalid users.
