Abstract

1. A circuit arrangement for connecting transmitting devices (Ta1 to Tax), which emit analogue signals, to receiving devices (Tax to Ta1), which receive analogue signals, via a t.d.m. data switching system (EDS) via which data signals which occur at a relatively low speed and items of signalling information can be switched, and which is assigned a special coupling device (K) via which data signals occuring at a relatively high speed can be switched and which for this purpose can be controlled by a control device (UEAS, SE, PE) of the t.d.m. data switching system (EDS), where the transmitting devices (Ta1 to Tax) and the receiving devices (Tax to Ta1) are in each case combined in groups via multiplexer-demultiplexer converters (MD1, MD2), each of which on the one hand converts analogue message signals with which it is supplied into digital message signals which it emits via message time channels which are allocated or assigned to the transmitting devices (Ta1 to Tax) and which occur in cyclic repetition in pulse frames, and on the other hand converts the digital message signals, with which it is supplied in the relevant message time channels, into analogue message signals which it emits to the receiving devices to which it is connected, and also emits, in a special signalling time channel, items of signalling information contained in all the analogue signals with which it is supplied, following their conversion into digital form, and similarly converts items of digital signalling information, with which it is supplied in the relevant signalling time channel, into items of analogue signalling information which it emits to the relevant receiving device (Tax to Ta1) of those receiving devices (Tax to Ta1) to which it is connected, characterised in that the signalling time channel is connected via a special signal converter arrangement (SU) only to the t.d.m. data switching system (EDS), and that the special coupling device (K) which is controlled by the t.d.m. data switching system (EDS) is connected only to the message time channels.
