摘要
This Recommendation defines the requirements for the optical transport module of order n (OTM-n) signals of the optical transport network, in terms of:-optical transport hierarchy (OTH);-functionality of the overhead in support of multi-wavelength optical networks;-frame structures;-bit rates;-formats for mapping client signals.The first revision of this Recommendation includes the text of amendment 1 (ODUk virtual concatenation, ODUk multiplexing, backward IAE), extension of physical interface specification, ODUk APS/PCC signal definition and several editorial enhancements.
