摘要
Disclosed is a device for transmitting data in an SDH or a PDH transmission system, comprising a device (2) for arranging data coming in through several data channels in flexible length minicells (7) and a device (3) for generating a single data on the basis of said the minicells (7). The inventive device is characterized by a device (6) that directly generates transmission for the SDH or the PDH transmission system on the basis of the data flow. The invention also includes a method for sending data in an SDH or a PDH transmission system, comprising the following steps: arranging the data coming in through several data channels in flexible length minicells; generating a single data flow on the basis of the minicells and directly generating transmission frames for the SDH or PDH transmission system on the basis of the data flow. The present invention further comprises a corresponding device and a corresponding method for receiving such data in an SDH or PDH transmission system. The invention enables the use of existing and pending AAL2 standards by avoiding transmission band width losses associated with the use of ATM cells.
