Embodiment Construction

[0018] The basic idea of ​​the method of the present invention is to make full use of the conference function of the digital dispatching communication system itself, and expand the voice channel of the original digital dispatching communication system, so that it can realize the analog dispatching extension and the dispatching switchboard without signaling. call directly.

[0019] Existing digital dispatch communication systems generally have conference, inter-office and internal call functions. These functions ensure the realizability of the method.

[0020] refer to figure 1 As shown, in this embodiment, there is a dispatching station in a digital dispatching communication system, which adopts 2B+D interface, so there are two voice channels: B1 and B2. In order to realize that the analog dispatching extension can directly communicate with the dispatching host without signaling, the following solutions are adopted:

[0021] 1. Allocate meeting time slots for the dispatchin...

Abstract

The invention discloses method for realizing direct call between analog dispatching extension and dispatching telephone exchange without signaling in digital dispatching communication system. The method includes following steps: (1) assigning conference resources for each analog dispatching extension; (2) connecting a voice channel of dispatching desk to the conference; (3) using time slot of conference as extended channel of voice channel; (4) connecting analog dispatching line to conference. Using advanced digital dispatching communication system replaces previous analog dispatching telephone exchange. Features are: simple implementing procedure, and easy of use.

Description

technical field [0001] The invention relates to a method for realizing direct communication between an analog dispatch extension and a dispatch switchboard without signaling in a digital dispatch communication system, and belongs to the technical field of railway special communication. Background technique [0002] The railway dedicated communication system directly serves the front line of transportation production and is the nerve center of railway transportation. It includes dispatching communication system, maintenance communication system, station communication system and interval communication system, etc. In order to ensure the unimpeded, safe and high-speed train, the railway special communication system must provide rapid, accurate and reliable service. [0003] In the dispatching communication system in the early years, a large number of analog dispatching switchboards were used. It is a relatively old-fashioned analog dispatching equipment. Its main functions are...
