Summary:
|
Amendment 1 to Recommendation ITU-T G.989.1 (2013) provides additional information on protection and/or restoration in NG-PON2 networks using flexible wavelength scheduling, which is not covered in section 9.4, as well as other new requirements of G.989 series systems not captured in ITU-T G.989.1 (2013).
Requirements identified for inclusion in this Amendment are:
- Network protection in the multi-wavelength access system case. In particular, the possibility of ODN topologies that appear to be type B (shared splitter), but provide additional capabilities. Also, the potential for 1:n protection in addition to the 1:1 protection previously described.
- Transport of wireless front-haul links over the access system. Such links have exceptional service requirements, and these are evolving as that application develops in the industry.
