## Check on programmable parameters for facilities

For facilities and various connection cases there exist a number of programmable parameters that need to be programmed correctly for the facility to function. See "Facilities" in RASC.

In addition there is a traffic group matrix that states the authorisation for different connection cases. The traffic group matrix can be used to verify connection paths, e.g. A may call B but B may not call A.
