Abstract

1. Communication system with a switching matrix (DE) for broadband signals (BB1, ..., BIF) and narrowband signals (SB1, SB2, ...) which are applied to the input side of the switching matrix (DE) and switched therein to lines (AL1, AL2, ...) leading to the individual subscriber terminals and with a control (ST) which controls the switching elements (K11, K12, ...) of the switching matrix (DE), characterised in that the switching elements (K11, ...) are switched through in such a way that a time division multiplex signal (TL1, TL2, ...) containing at least two broadband signals (BB1, BB2) and one narrowband signal (SB1) is delivered directly to the output line (AL1, ...) leading to the selected subscriber terminal.
