Digital Trunk Communication System
General
Possessing dispatching and commanding function, the Digital Trunk Communication system is designed based on domestic and foreign standards, it adopts large area network establishment, and owns the advantages of high utilization of spectrum, compatible with analog system, abundant operation functions, various of networking modes, fine RF (radio frequency) performance, far covering distance by single BS(base station) and high voice quality.
Application Field
The Digital Trunk Communication System is applied in daily communication, emergency communication, command and dispatch in the military, police, anti-terrorist, fire prevention, fishery, port and other industries.
Command and Dispatch System
Composed of dispatch terminal and dispatch server, the
system plays a management role in commanding and
dispatching voice and data communication in the system.
Functions
Voice Call
Tele-conversation
SMS
User Registration and Limitation
Database Backup
Map Lock and Fense, Map Over-range Alarm and Map Trace
Remote Kill and Control on Radio
Voice Record and Playback
Log Selection
Network Management System
Monitor and allocate the states of each equipment inside the whole trunking system and make the record based on the stored logs.
Forest Fire Fighting Communication Solution
Three-level (province, city, county) forest fire fighting command and dispatch network framework based on provincial network will be formed by building a large number of fixed base stations and IP network connection to command and dispatch platform for each base station.
Fishing Communication Solution
Factory sets up lots of fixed BS on land and on islands to guarantee the voice communication, data communication and telephone interconnection of fishery law enforcement on land and islands so as to improve the commanding and dispatching ability and law enforcement efficiency.
Port Communication Solution
Factory has set up a base station with 8 carrier(consisting of 15 voice channel and 1 control channel).The solution adopting full IP structure consists of base station , dispatching system, network management system etc., which can meet different levels of application requirement for port end user and bring user a new communication experience.
Civil Air Defense Communication Solution
Fixed Base Station
Communication covering in large area and networking.
Vehicular Base station
Mobile communication and field area coverage to realize ad hoc network interconnection with the nearby base station.
Portable Base Station
Adopting portable integrated design and built-in storage battery, it’s flexible to use, easy to carry, suitable to rapid deployment.
Fiber Optic Repeater
As for the signal covering of underground civil air defense project, the fiber optic repeater is employed underground , which makes supplement of signal covering where the BS signals underground hardly reach.
Fleet Communication Solution
DMR repeater/BS are connected by basic network IP link to realize IP digital simulcast mode, intelligent channel networking mode and trunking mode with control channel.
This solution can realize VHF BS ad hoc network to satisfy the communication requirement in high mountain, desert, and vehicle without by basic network IP link.
