Abstract

Appts. in a digital communication system connects digital terminals to a terminal junction point which in turn is connected to a digital exchange. The junction point contains a directing unit sending, in a first state, a flag signal to all terminals as well as to the exchange, this signal being utilised as filling-out information, and in its second state sending an information packet received from a terminal towards the exchange as well as to all terminals. The terminals contain units for sending out on information packet in response to the flag signal having been received a given number of times, the reception of the information pocket at the junction point resetting the directing unit to its second state. The terminals also contain a comparator for determining whether the packet information sent back from the junction point corresponds to the terminal's sum sent out packet information and for disconnecting the terminal in the opposite case. This gives multiple access to a digital subscriber line and enables the utilisation of the same terminal interface for both bus and star structures.
