Abstract
A method and apparatus are provided for de-multiplexing one or more Low-Order ODUj/ODUflex clients from a High-Order ODUk carrier. The number of TribSlots assigned to an ODUflex may be increased and decreased hitlessly, in accordance to ITU-T G.7044. In the Multiplexing direction, a Space-Time-Space switch is used to interleave bytes from Low-Order ODUk words into High-Order ODUk words. In the De-multiplexing direction, a similar switch is used to extract Low-Order ODUj bytes that are interleaved inside High-Order ODUk words and re-arrange them into Low-Order ODUj words.
