• System functions and equipment specifications are totally compliant with the GA176-1998 police use standard of Police Automatic Network Scheme—One of Mobile Communications for Public Security.
• Totally compatible with trunking terminals compliant with the MPT1327 and MPT1343/CPSX standards.
• Centralized and decentralized controls are combined together. Group call is shorter than 300ms; individual call is shorter than 500ms; inter-system call is shorter than 1s.
• Automatic switch between PABX/PSTN subscribers and radio. Each system user can call PABX/PSTN to access the local programme-controlled exchange directly.
• Users can roam among multiple base stations and systems automatically.
• Flexible handling of group calls among multiple base stations. Set each group call with a home base station, saving channel resource and reducing the number of missed calls as much as possible.
• Flexible setting of inter-system group call among multiple systems, avoiding unnecessary waste of channel resource.
• Group calls among multiple systems have the feature of group call maintenance. Users return to the talking group when stepping over the base station during communication.
• Multi-level Fail Soft
The system can close the malfunctioned channel automatically on which interfered receiver, low power of transmitter, malfunction for power supply of transceiver or link malfunction occurs.
• Three-level Networking
• Both signaling and audio are controlled by three levels, strengthening the fail soft capability and applicable for networking at county, municipal and provincial levels.
• Flexible Networking
Allow the coexistence of 2M transmission network (using the technology of IP over SDH), IP local area network, satellite network, CDMA, ADSL, etc.
• The networking center only has one server, easy for upgrade (upgrading software remotely) and remote maintenance.
• Powerful Exchange Capability
Use the soft exchange technology, not restricted by the dedicated exchange hardware and easy for constructing network with wide coverage.
• Small audio distortion
Audio undergoes the analog-to-digit conversion once no matter how many networking centers and exchanges are passed.
• Overall Network Management and Maintenance
Log on remotely, to perform real-time monitoring and controlling on system resources and networking equipment.
• Based on the full IP platform, functions as network management and dispatch (e.g. inter-system monitoring, recording, etc. can be expanded easily.
• Network Dispatcher Based on Full IP
Dispatch all users within the network in different places through the IP network and realize perfect dispatch functions as individual call, group call, all call, include call; channel monitoring, maintenance, disconnection, forced monitoring; dynamic regrouping, channel open, call forward, plan recording and saving, tracking record.
