Abstract
In asynchronous mode transmission for multiple-service networks with a wide range of throughput rates, it is stipulated that the digital data will be conveyed in standard cells having a header and a data field, with fixed lengths. For the low throughput rate services, which are penalized by this type of transmission as regards their transmission efficiency, the method disclosed provides for the transmission, while performing all the switching operations on the standardized cells, of microcells on those trunk lines where this type of transmission occupies a major place. These microcells result from the cutting up of the standardized cells, preventing the transmission of unnecessary data field lengths.
