As a system variant, Multicall safe combines the technologically secure features of the multicall MP2 bus system at ward level with the flexibility of modern IP systems for cross-ward structures. At the same time, conventional old systems from recent decades can be combined with new construction phases and integrated into new structures.
The previous system line (Seriobus) will be replaced by an IP network; the previous limit of 59 stations per system will now be increased to up to 255 stations. IP networking creates
Any number of voice connections between the stations.
The core of this structure is an IP station interface (IP-SI) instead of the station control centers (SC) for data and voice transmission that are otherwise used.
The IP ward interface integrates a ward set up using bus technology into an IP network that links the wards together.
