Figure 15 Hardware and interfaces of the CC–2M
The task of the Communication Converter CC–2M is to perform an adaptation of the
available fibre optic active interface in the protection device to the physical specification of
the respective interface of the communication network. The adaptation occurs synchronous-
ly and completely bit–transparent, i.e. direct forwarding of the information without adding or
filtering out information. Figure 15 shows the hardware and the interfaces.
The parameter assignment of the CC–2M is done via jumpers.
