Document Type and Number:

WIPO Patent Application WO/2021/088345

Kind Code:

A1

Abstract:

The present invention provides an ED137 protocol-based VoIP station gateway having a master-backup architecture. The VoIP station gateway device uses a VoIP design method to design a VoIP station access interface, a VCC access scheme, and a master-backup redundancy function strictly according to the ED137 protocol. Various additional functions, such as working modes, gains, and delay are added. Specific functions such as CLIMAX, BSS, and dynamic delay compensation are realized, greatly embodying the advantages of a VoIP station. The VoIP station gateway can access a VoIP station receiver, a VoIP station transmitter, a VoIP station transceiver, a VoIP station remote control device, etc. The VoIP station gateway is provided with a friendly front-end management terminal, and all functions thereof can be managed and configured by means of web access. The present invention satisfies not only the requirements of an airline management voice system for a VoIP station, but also the requirements of airline management safety redundancy.
