Abstract

The communication device (KE) has a coupling arrangement (ASN) with at least a number N of active line assemblies (BG 1 to BG N), which are respectively connected to a transmission line (LTG 1 to LTG N) and, together with an additional standby line assembly (BG N+1), form a “1:N” redundancy group. In such a “1:N” redundancy group, line-specific switches (S) and selection devices (SEL 1:N) are designed and arranged in such a manner that the selection devices can be replaced without adversely affecting the normal operation of the communication device.
