Abstract
Apparatus (D1) is dedicated to processing STM-n/STS-m type data frames in a communications network. It comprises at least one STM-n/STS-m interface unit (LIU1) adapted to receive STM-n/STS-m type data frames from a communications network and processor means (MTj) adapted, on receiving data from an STM-n/STS-m frame coming from said line interface unit (LIU1): i) to segment the whole of said received frame into m groups of p successive bytes; ii) then to associate with each group a control header containing data representing its position within the STM-n/STS-m frame; and iii) to encapsulate each group and the associated control header in a payload data field of an Ethernet frame.
