Abstract

For ensuring power supply, e.g. to an ISDN network basic access, a common DC voltage converter (GW) is provided which comprises two primary circuits (T1, w1; T2, w2) fitted with final control devices (T1, T2). The secondary circuits are controlled by a locking device (VO) powered either by a normal supply source (VN) or a remote supply source (VF).
