Raytrans Core Resources or Technical Means Used by Products or Services -- Integrated Service Transmission and Access Gateway

I. Integrated Service Transmission and Access Gateway

1.1 Technical Features

Unified access of multiple communication terminals (fixed telephones, mobile phones, trunking radios, wireless transceivers, magneto telephones, public address systems, access control intercoms, satellite phones, cameras, display terminals, IoT sensors, etc.) and transmission equipment (optical fiber, twisted pair, wireless broadband, wireless narrowband, BeiDou SMS, etc.), with conversion into standard SIP transport and switching protocols, standard MQTT protocols, etc.

1.2 Main Functions

(1). Terminal interface protocol conversion, including interface level to SIP, interface serial port protocol to SIP, other network interface protocols to SIP, conversion to MQTT, etc. Achieving normalized conversion from multiple interfaces to SIP and MQTT, etc.

(2). Used only for traditional diverse terminals and transmission equipment, accessing the same system through converged communication means.

(3). A modular converged dispatch integrated gateway product developed for special applications, with powerful signaling and media processing capabilities, integrating various communication interfaces, supporting E1, FXO/FXS, 4G LTE, trunking interface/mobile radio/handheld radio, audio/shortwave/ultra-shortwave, E&M interface, magneto interface, SIP, etc. Supports dual power supplies, mainly applied in specific industries such as IPCC, SIP dispatch, and unified communications.

1.3 Networking Applications

Supports access of up to 170 channels of 64K timeslot services, combining voice, audio/video, and LAN communication services into one high-speed data stream, then transmitting bidirectionally over DDN leased lines, microwave, satellite, and other communication links. Supports audio service transparent transmission, data service transparent transmission, and Ethernet channel physical isolation transparent transmission.

Telephone central office interface FXO, telephone set interface FXS, radio interface/PTT handset interface, LTE mobile phone interface, magneto telephone interface, public address interface, and mixer interface can all be uniformly dispatched at the dispatch console.

1.4 Core Technologies

Interface level conversion analysis technology; interface level timing conversion analysis technology; interface protocol conversion analysis technology; interface audio and video encoding conversion analysis technology.

1.5 Innovation Points
