Abstract

In an interface unit (FAU) for connecting a PCM transmission path (PCM-Ü) to an exchange of a TDM telecommunications system, the supervisory circuits (Ü1 to Ün) of the system, which monitor information transmission criteria, should be monitored in such a way that their actual function is interrupted for a short time only. To achieve this, they are supplied successively with simulated parameters corresponding to an error event, even if they transmit one group- individual alarm signal only. If an error signal is produced, the supply of simulated parameters is immediately interrupted. If no error signal of this type occurs, the simulated parameters are fed in at least once more. <IMAGE>
