  • In the OLS domain, we need to represent a network-level media channel that is wider spectrum than NMC, but narrower than OMS.
    • We call it SMC - service media channel
    • All the connectivity in the OLS domain is made at this SMC granularity
    • SMC spectrum width at each ROADM Node could potentially be different
      • In such a case, the spectrum width of network-level SMC should be an intersection of all Node-level SMCs
  • Photonic OAM Model in OLS: The OTSiA really represents the OAM aspects
