Method for switching a first to a second communications link, which in each case between a first and a second communication system are

摘要

A first and a second communication system (NKn, NKm-1) are connected through a first link (V1), which uses a first communication network (IN), and through a second link (V2) which uses a second communication network (ISDN). Said first and second link (V1, V2) exhibit, for every communication system (NKn, NKm-1), a transmitting channel (SW) used by the communication system (NKn, NKm-1) for transmission, and a receiving channel (HW) used by said communication system (NKn, NKm-1) for reception. The first link (V1) is switched to the second link (V2) in such a way that the transmitting channel (SW) and the receiving channel (HW) of a communication system (NKn, NKm-1) are switched, at different times, from the first link to the second link (V1, V2).
