7. Modules
This chapter provides detailed technical information on the modules which can be
installed in the OpenCom 510. You will find information on their respective fields
of application, along with technical and operational information and notes on
indicators.
The modules fulfil the following tasks:
■
Power supply units (max. 2) provide the OpenCom 510 with power.
■
A central control module controls the entire system. This module also houses
the memory card (CompactFlash) for storing data.
■
Interface cards are used to connect the OpenCom 510 to the telecommunica-
tions network (or to another communications system) and to connect ter-
minals.
A number of interface cards are available for these tasks. Depending on the
interface card's functions, it may also be referred to as a trunk module or as a
subscriber module.
For detailed information on installing modules, refer to the chapter Installing
