Patent DE-4104238-A1 (DE)
Inventor: MUELLER HORST DIPL ING
IPC: H04J3/16
Filed: 1991-02-12
Abstract: A plurality of terminals, including those (AE1) for STM-1 signals in the synchronous-digital hierarchy (SDH), is connected in a cross-connect multiplexer (CCM2) to a space coupling field (RKF). The section overheads of these synchronous transport modules (STM-1) are overall partially received and evaluated in a section overhead server (SOHS) with the aid of a network node computer (NCU) and partially interlaced and transmitted. This process is simplified in that STM-1 signals are transformed into several known D39 signals with a bit rate of 38.912 Mbit/s and vice versa, whereby via the frame coupling field (RKF) only the bytes of the section overheads needed for transmission are inserted into only one of the sixteen frame columns of a D39 signal belonging to the STM-1 signal. Only these special columns of each group of sixteen STM-1 signals are combined into an actual D39 signal which the section overhead server (SOHS) receives or transmits. Such cross-connect multiplexers (CCM2) are inserted in network nodes of digital networks.
