Abstract
Network elements of a first synchronous transport network are to be connected to one another via a second synchronous transport network. For this purpose a frame (STM-4) to be transmitted, including the unchanged overhead sections (MS-OH, RS-OH, AU-PTR) thereof, is packed as payload in a concatenation (VC-4-5v) of newly formed multiplex units (VC-4v) and transmitted in newly formed transport modules via the second transport network.
Claims10
A method of transmitting, via a synchronous digital transport network, a frame-structured synchronous multiplex signal, composed of frames having a payload section and an overhead section, in the payload section of which multiplex units are multiplexed according to a multiplex hierarchy, comprising the step of transmitting a frame to be transmitted, including its unchanged overhead section, as payload in a concatenation of newly formed multiplex units.
A multiplexer for a synchronous digital transport network comprising:
- at least one tributary input for receiving a first frame-structured synchronous multiplex signal being composed of first frames each having a payload section and an overhead section, in the payload sections of which multiplex units are inserted in accordance with a multiplex hierarchy,
- a multiplex device, connected to the tributary input, for creating new multiplex units, for concatenating the newly formed multiplex units to form a concatenation, and for packing a received frame, including the unchanged overhead sections thereof, as payload in the concatenation of the newly formed multiplex units, and
- at least one output for creating and transmitting a second, frame-structured synchronous multiplex signal composed of second frames in whose payload sections the concatenated, newly formed multiplex units are inserted.
