Abstract
A method for transmitting 1544 or 6312-kbit/s signals via a 2048 or 8448-kbit/s link is not known in the synchronous digital multiplex hierarchy and is to be specified. A 1544-kbit/s signal is inserted in the direction of multiplexing, using a gapped 2048-kHz clock (LT11) into a container C-111 which is completed by means of a path overhead V511 to form a virtual container VC-1111. This is transmitted via a 2048-kbit/s link (L11) with a link container (S-1111) to which a header (OH11) and pointer bytes V111 to V411 are allocated for the transmission. After adding stuffing bytes (FS11), the 1544-kbit/s signal can be fed into a subsystem unit TU-121. In the direction of demultiplexing, stuffing bytes (FS12) must be removed from a subsystem unit TU-122 and pointer bytes V112 to V412 must be inserted with the aid of a gapped 2048-kHz clock (LT12) and a header (OH12) must be inserted with the aid of a 2048-kHz clock (T12) for the transmission via a 2048-kbit/s link (L12). After the transmission, the header (OH12), the pointer bytes V112 to V412 and a path overhead V512 are removed so that the 1544-kbit/s signal can be taken from a container C-112. A 6312-kbit/s signal is transmitted correspondingly. <IMAGE>
