The exchange (KS) has at least one central control device (ZS) and at least one energy supply (SV1..n,S). The central control device cooperates with additional control means (SM1..n) to switch at least one section (SLM...n) of the exchange to an energy-saving operating mode, when an energy-saving information (ei) is received. The energy-saving information may be provided by internal or external means (UM,ESR,PZE) and can be used to disconnect the current for a selected section of the exchange, or to switch the selected section to a stand-by mode, in which it receives a min. stand-by current. <IMAGE> |
