Apparatus for hybrid-transmitting and bridging of a circuit service and a packet service

摘要

An apparatus and a system for hybrid-transmitting and bridging of a circuit service and a packet service are provided. The apparatus includes a TDM framing unit, a TDM three-direction cross unit, and a mapping and encapsulating unit. The TDM framing unit implements conversion between a line layer TDM signal outside the apparatus and channel layer TDM signals inside the apparatus, and transmits the channel layer TDM signals to the TDM three-direction cross unit. The TDM three-direction cross unit implements cross scheduling on the channel layer TDM signals from a TDM cross apparatus, the mapping and encapsulating unit, and the TDM framing unit. The mapping and encapsulating unit implements conversion between a channel layer TDM signal from the TDM three-direction cross unit and packet service signals from the packet processing unit.
