In today's communities the need for mobile messaging is increasing. Certain groups, e.g. Rescue professionals, have set high demands on receiving the alarm messages in real-time. It is also of greatest importance that messages always gets through – anytime and everywhere. With the Axentia DARC Paging System you get a robust and secure system, dedicated for broadcast and group messaging services via the FM-network.

Turn-key System
The Axentia DARC Paging system enables multiple message senders (Paging Terminals) to connect to a central Paging Server and deliver their messages using a high-level addressing scheme. The Paging Server formats the messages, resolves addressing issues and transmits the messages over DARC using standard Axentia server software. The receivers are always online and will notify the user immediately when a message arrives.

Addressing
The addressing concept is central to the Paging System since it allows a message to be directed to all receivers, one specific receiver or a group of receivers.

The DARC Paging System offers three ways to address a message.
•  all receivers
•  an individual receiver or
•  a group of receivers

Priority
The priority handling is essential to the Axentia DARC Paging System. The DARC Network Server, the heart of the system, is designed to balance the load to the DARC encoders depending on the service's priority and allocated bandwidth. Buffers in the DARC encoders handle any temporary overload. The DARC Network Server will stop sending data on services with lower priority when the channel is full. The stopped data will be buffered in the input queues in the DARC Network Server for later transmission if the load decreases. To maximize the usage of bandwidth, it is possible to over-allocate the channel. The transmission of higher priority messages in a situation where the total load exceeds 100% is still guaranteed.
