Operating desk implementing method of digital dispatching communication system

Abstract

The invention discloses a method of realizing a digital dispatching communications system service platform which belongs to the communications technology field. The invention increases an U interface adapter between an U interface of the communications system and an operating terminal. The U interface adapter can be connected with two common telephones used as two conversation handles. The telephone has functions of ringing, dialing, listening to dialling tone and so on, and usage of the functions is essentially identical with the usage of a common SPC exchange telephone, so as to guarantee that when the service platform is halted or power-failed, two telephone can still be regular serviced, and guarantee the lowest communication of the dispatching system and communication reliability of the dispatching system, and also increase flexibility of configuration and using of the system.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for realizing an operation console of a digital dispatching communication system, which can ensure that the operation terminal can still communicate normally when the operation terminal crashes or loses power. Background technique [0002] In the digital communication system dedicated to dispatching, it usually includes several dispatching consoles, or duty consoles or attendant consoles, which are collectively referred to as operating consoles in this paper. The designed touch operation terminal can only use local 220V power supply due to the power limit of the operation console. [0003] Fig. 1 is the structural schematic diagram of the existing implementation method using the console of the dispatching communication system; the U interface 4 of the communication subsystem 3 is connected with the built-in U interface adapter card of the console 1; the...

Problems solved by technology

[0004] The main problem of the above scheme is: if it is a computer mode or a self-designed operation terminal, a U interface adapter card needs to be added, and the external line access of the system is inconvenient, and all voice lines, recording lines, power lines, and handles need to be connected Lines must be connected to the computer mainframe; the call handle 2 does not have a dial-up function; the U interface adapter card is a kind of interface card developed based on ISA or PCI slot, and is powered by the computer power supply centralizedly, so when the external power supply When the power is off, the console will lose all functions; when the computer crashes due to operating system, virus, application software, etc., it will also lose all functions; in addition, when the U interface adapter card is damaged for some reason and needs to be repaired, it needs to be dismantled. When the host is turned on, the communication service is interrupted, which is not convenient for system maintenance
