Desi Wireless Cluster Gateway

The multimedia dispatching and commanding system is a new type of dispatching and commanding system. It is characterized by the integration of various means of communication such as voice and video, and effective management and scheduling of multiple communication means. The command and dispatch system helps command and dispatch personnel through multimedia. Ways to achieve scheduling. This system is a highly integrated communication system. When integrating multiple communication methods, multiple gateway devices must be equipped. The more familiar ones are the telephone voice gateways, such as FXO gateways, FXS gateways, and GSM wireless gateways. , E1 digital trunking gateways, etc. These gateway devices facilitate the integration of PSTN telephony networks for efficient scheduling of telephone networks.

It is not enough for the current multimedia emergency dispatch and command system to only access the telephone network. When dealing with emergency dispatch operations, it is often necessary to integrate various wireless cluster systems, analog clusters, digital trunks, 350 megabits, 800 megabytes, and shortwave radios. . This type of wireless cluster system has irreplaceable advantages in dealing with on-site emergency scenarios, but its unique design makes it impossible to perform effective full-duplex calls and is not very convenient when communicating with the telephone network. Basically, it is a Set of independent communication systems. If you want to access the cluster intercom system to the multimedia dispatching and command system, you must configure the interworking gateway, also called the cluster intercom gateway device. This type of gateway device connects the wireless trunking communication to the telephone system in a ROIP manner. Generally, the SIP protocol is used to interface with the dispatching command server and the softswitch system to realize convenient and fast convergence of communication. The user can use the dispatcher, mobile phone, and telephone at any time. Talk to the wireless cluster intercom platform.

Desiite AOS4000 series interworking gateway is a professional cluster scheduling gateway, supports 1-4 channels of wireless cluster intercom interface, with 1-4 SIP accounts, compatible with standard SIP server, dispatch command server, softswitch, IP- PBX and IP telephone exchanges cooperate to support WEB management. Delayed voice transmission, VAD automatic voice detection, adjustable voice detection sensitivity at any time. When connecting to various cluster systems, there will be no problems such as howling, missing words, single communication, and disconnection.

Device features - to achieve interconnection between different wireless devices wired devices - support G.711, G.729, G.723 a variety of voice compression algorithms - support for multiple dialing, number collection rules - support for DTMF detection - since Adapt to VOX (Voice Activation), Sensitivity is Adjustable - COR, PTT Signal Valid Signals can be User Defined Definitions - Input, Output Volume, Gain Adjustable - Support WEB-Based Management Control - Supports Automatic Speech Level Detection - Support Buffer control, cache parameters can be configured to avoid delayed word dropping and other phenomena Desi AOS4000 series interconnection gateway is widely used in government emergency dispatch command, air defense emergency dispatch command, power dispatch command, * cluster dispatch command, military exercise command system, vehicle Emergency dispatch command, portable emergency dispatch command, meteorological dispatch command, fire command dispatch system, forest fire dispatch command, water conservancy system dispatch command, guard dispatch command system and other professional industry applications.
