ABSTRACT:
A communication system is prepared to be placed into service, or an in-service system is updated or re-started, by transmitting programs and data into the peripheral equipment of the communication system. So that the availability of the communication system for the connected subscribers remains assured, there is a need for accelerated loading. The loading ensues by segmenting the programs and data on the storage medium at the central station as well as by the transmission of the segments into the designated peripheral units. A synchronous connection is provided between two redundant peripheral units forming a pair and is utilized in the loading event to transfer data or programs as needed between the units of the pair.
