Device for transmitting in an asynchronous network, especially an ATM-network, channel-by-channel signalling data gathered in a multiframe synchronously transmitted out-of-band

摘要

The information being conveyed, in the asynchronous network, by data bit packets each formed of an information cell (8) comprising, on the one hand, a header carrying an address and, on the other hand, a useful field carrying the information to be transmitted, the device of the invention is characterised in that it comprises: … …  - at the transmission end: means (10) for acquiring the signalling data of each channel of the multiframe (9); means (11) for detecting the changes of state of these data; and means (12) for generating on the network, with each change thus detected, an information cell containing the new signalling datum and the address associated with the corresponding channel, and …  - at the reception end, means (14) for acquiring from the network the information cells containing signalling data; means (15) for storing these signalling data between each corresponding change of state; and means (16) for inserting the data thus stored into a multiframe and for transmitting the latter in out-of-band synchronous manner. … ……
