The digital relay gateway provides E1 interface and can be interconnected with PSTN/PABX using signaling methods such as NO.7 and Q.931. Loop relay provides FXO interface, which can achieve interconnection with PSTN/PABX. In addition, wireless access gateways are used to achieve the access of digital/analog cluster network terminals such as car stations/hand stations and related cluster business functions;
Utilize wireless access gateways to achieve the access of terminals such as digital/analog cluster networks, vehicle stations, and handheld stations, and achieve interoperability between terminals in each cluster. Wireless communication, as a reliable technical means of emergency command on-site communication, can assist leaders in quickly and efficiently issuing command decisions, achieving accurate and rapid control of command and dispatch.
Ø Comprehensive dispatch console: an integrated platform that integrates operation, control, command, and control, supporting various dispatch consoles such as all-in-one touch screen operation console, mobile Pad operation console, and all-in-one dispatch console. It mainly provides voice scheduling, video scheduling, GIS scheduling functions, as well as a unified control and management operation display interface for third-party business data information access. It provides a graphical human-computer interactive interface display, and can switch between different interfaces through touch and click switching. It supports hierarchical scheduling function.
Ø APP Download Server: Connected to the main server via IP, providing multimedia cluster system software services such as downloading and upgrading multimedia cluster system APP software
Configure a dedicated audio and video recording system that can record scheduling calls, video calls, and audio and video scheduling meetings. Recording files can be stored on recording servers or other storage devices as needed. The recording system has comprehensive recording management functions, which can perform playback, download, delete, query and other management operations on recording files.
Ø Adding a PC can serve as a system management and maintenance platform (extension), supporting configuration, management, and maintenance of the entire system, achieving unified local or remote management of all network elements.

1.1.2 Business Functions

1.1.2.1 Function Description

1.1.2.1.1 Group call

Group call refers to multiple users in a half duplex group, and authorized individuals can initiate group calls. Only one person can speak in a group call at the same time.

1.1.2.1.2 Point Call

Point to point full duplex call, where both parties can receive and send media simultaneously.

1.1.2.1.3 Single call

Single call refers to a half duplex call between two cluster terminals, where only one person is speaking at the same time. The difference between him and group calling is that only two users participate.

1.1.2.1.4 Single work broadcasting

Single broadcast call refers to establishing a group call, but no one in the group can speak except for the initiator. The initiator needs to press the PTT key to speak.

1.1.2.1.5 Call for Rights

Call preemption refers to the situation where in single call and group call, users with higher priority can seize the speaking rights of users with lower priority. This way, users with higher priority can switch from listeners to speakers, while users with lower priority can switch from speakers to listeners.

1.1.2.1.6 Call preemption

Call preemption refers to when a user is in a low priority call (which can be a group call, point call, single call, or simplex broadcast), and when a high priority call is initiated and the user needs to be added, the system will first remove the user from the original call and add them to a new high priority call.

1.1.2.1.7 Supplementary Services

Full duplex call value-added services include:
1. Call forward unconditionally
2. Call before being busy
3. Call forwarded before no response
4. Call unreachable forward transfer
5. Call forwarding
6. Limit outgoing calls
7. Restrict incoming calls
8. Caller ID display
9. Called number recognition display
10. Black and White List
