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

An apparatus for hybrid-transmitting and bridging of a circuit service and a packet service, the apparatus comprising a TDM framing unit, a TDM three-direction cross unit, and a mapping and encapsulating unit;

• wherein:
• the TDM framing unit is connected to the TDM three-direction cross unit, is configured to implement conversion between a line layer TDM signal outside the apparatus and channel layer TDM signals inside the apparatus, and is configured to transmit the channel layer TDM signals to the TDM three-direction cross unit;
• the TDM three-direction cross unit is connected to the TDM framing unit, the mapping and encapsulating unit, and a TDM cross apparatus outside the apparatus, and is configured to perform cross scheduling on the channel layer TDM signals from the TDM cross apparatus, the mapping and encapsulating unit, and the TDM framing unit;
• and
• the mapping and encapsulating unit is connected to the TDM three-direction cross unit and the packet processing unit, is configured to implement conversion between a channel layer TDM signal from the TDM three-direction cross unit and packet service signals from the packet processing unit.
