Body 
ITU-T SG15 Q9 is pleased to inform you that Recommendation ITU-T G.798
“Characteristics of OTN Hierarchy Equipment Functional Blocks” and its
Amendment 1 have been approved. ITU-T G.798 specifies both components and
methodology that should be used to specify OTN functionality of network
elements. The components are specified to support ODUs and client signal bit
rates up to 100Gbit/s. It is used as the basis to develop ITU-T G.874
“Management aspects of the optical transport network element” Amendment 1
contains additional text to ITU-T G.798 to complete the specification of the
mapping of  Ethernet Rates  (40GBE and 100GBE into ODU3 and ODU4 respectively)
as well as additional management information needed for ODU PT21 (ie. time
slots of 1.25Gbit/s) multiplexing. An AIS generator for pre-emption of extra
traffic is also added to the ODU connection functions.
