Abstract

An ISDN subscriber installation (TLN) equipped with a transmission device (IBC, IEC) implemented by means of integrated circuits and with a communication protocol control device (ICC) and a subscriber installation control (TST) is to be subsequently extended by means of an ISDN basic access interface (S0). For this purpose, the ISDN-oriented interface (IOM) of the ISDN basic access interface device (SBC), which is also implemented in integrated circuits, is connected in parallel to the ISDN-oriented interface (IOM) arranged between transmission device (IBC, IEC) and communication protocol control device (ICC). An additional connection (ZA) of the ISDN basic access interface device (SBC) - the connection is used for coordinating the access of several installations to one ISDN-oriented interface (IOM) - is connected to a connection of a microprocessor (MP) controlling the communication protocol control device (ICC). This microprocessor controls the access of the communication protocol control device (ICC) to the ISDN-oriented interface (IOM) in the same manner as the access of several ISDN basic access interface devices (SBC) to one ISDN-oriented interface (IOM). <IMAGE>
