ABSTRACT:
A method and apparatus for alignment of TDM-based signals for packet transmission using framed and unframed operations are described. In an embodiment, a line card in a network element includes a deframer unit that receives a Time Division Multiplexing (TDM) signal. The TDM signal includes a payload and overhead data. The deframer generates frame alignment data based on the overhead data. The line card also includes a packet engine unit coupled to the deframer unit. The packet engine unit receives the payload, the overhead data and the frame alignment data and generates a number of packet engine packets. The packet engine packets represent a frame within the TDM signal such that the packet engine packets include the payload, the overhead data and the frame alignment data. Additionally, the line card includes packet processor coupled to the deframer unit. The packet processor receives the packet engine packets and generates network packets based on the packet engine packets.
