Flexible server concept for the system functions in the TETRA radio system ACCESSNET-T IP.
The IP Node (IPN) is a network element of the TETRA ACCESSNET-T IP radio system and serves for providing the switching function, as a server for the network management system and as an application server for the dispatcher and voice recorder, for example.
In ACCESSNET-T-IP networks with a centralized routing function, the IPN operates as a classical system controller node. In this context, an IPN Server handles the software-based routing function.
In addition, further IPN servers can be integrated to provide additional functions such as telephone interfaces (PABX/PSTN) or applications such as dispatchers.
The IPN is equipped with hardware according to the output requirements and network capacity to adapt it flexibly to the needs of the customer. Thus, depending on the respective requirements, the 19" equipment rack houses a different number of IPN servers and further components.
Depending on the desired scope of functions, the IPN can be expanded by additional qualified hardware. If a second IPN equipment rack is required, the two equipment racks can be stacked to save space.
