Method for transmitting data in a telecommunications exchange |
摘要 |
A method of transmitting data in a telecommunications exchange via a ring line system which allows information items to be transmitted in periodically recurring pulse frames. The pulse frames are split into at least two sub-frames, where in the first sub-frame the information is transmitted in a continuous transmission process whereas in the second sub-frame the information is transmitted in a burst process. The first sub-frame is divided into time slots which are allocated, as time channels, to a subscriber station for the establishment of a connection, such as a speech connection. In the second sub-frame the time slots are combined to form one single data channel for the transmission of data bursts. Access to the second sub-frame is gained by means of an item of so-called token information. Also transmitted as the data burst is information which contains a statement concerning the free/seized state of the time channels in the first sub-frame and which serves to bring up-to-date corresponding tables at the subscriber stations.
