Smart Sentry Post Fiber Self-Healing Ring Network Audio/Video Dispatch System
Keywords: Armed Police Optical Terminal, Sentry Post Optical Terminal, Sentry Post Intercom Terminal, Sentry Post Management All-in-One Machine, Self-Healing Ring Network Optical Terminal
In sentry post management, not only is high reliability of fiber transmission required, but the transmitted content is also extensive, including voice data, image data, IoT data, and information platform data.
The dispatch switch M9000 of this system supports sharing the registration server with the intercom management and control system, supports touchscreen dispatch consoles (sharing terminals with the sentry post management all-in-one machine), supports one-key direct dialing to extensions, connection to external lines, connection to intercom and trunked radio systems, and supports forced release, barge-in, transfer, monitoring, conferencing, and other functions!
Provide one dispatch telephone line for each sentry post, used for prioritized emergency dispatch;
Provide one administrative telephone line without dispatch functionality for each sentry post, facilitating external communication when needed;
Provide one audio broadcast channel for each sentry post, used for remote broadcasting from the central end;
Integrate an integrated fiber self-healing ring network transmission access, enabling continued communication in the event of a fiber fault or equipment failure at a certain point, thereby increasing system reliability;
The fiber line can provide two groups of physically isolated wire-speed Gigabit Ethernet channels: one group is used for the HD camera video surveillance system (the surveillance system is exposed outside the sentry booth and is at risk of IP attacks); the other group is used for the access of various information terminals.
The central end provides FXO administrative telephone interfaces for sentry posts, allowing convenient connection to program-controlled switches or IP switches;
Provide FXO interfaces for connection to dispatch trunk interfaces, used for connecting the dispatch system to external networks.
The central end equipment provides 2.5G Gigabit optical ports for remote ends, can provide STBUS bus for narrowband service access, and provides two wire-speed Gigabit Ethernet interfaces, used to form a fiber self-healing ring network with remote end equipment; to ensure system reliability and the number of services per site (4 narrowband services reserved per site), each self-healing ring should not exceed 7 sites (4*7=28 64K timeslots);
The central end dispatch switch has a recording output interface;
This dispatch switch provides 12 user board slots, which can accommodate telephone boards, GPuser expansion boards, etc. The total capacity of local and remote services is 120 channels.
The GPuser board provides a fiber self-healing ring network interface for the IDM GTD442, offering 2 wire-speed Gigabit interfaces and 1 E1 narrowband interface.
The IDM GTD442 is a transmission device that can be integrated with the dispatch switch. The two groups of wire-speed 1000M IP interfaces it provides can be either two groups of 1 optical + 1 electrical, or two groups of 2 optical + 2 electrical. The narrowband interfaces can be FXS, FXO, MSG magneto, EM 2/4-wire audio, and other interfaces.
