ABSTRACT:
In a program-controlled telecommunication system (KS), at least sub-areas (SLM1..n) are controlled into an energy-saving mode with reduced energy consumption using a central controller (ZS) and additional controllers (SM) given the presence of energy-saving information (ei). The energy-saving information (ei) are formed, for example, using a timer (UM) in the telecommunication system (KS) and using an implemented energy-saving routine (ESR). A telecommunication system (KS) fashioned in this way can be controlled into an energy-saving mode, for example during the night or over weekends.
