Need for layer0-bandwidth-type identies

[italobusi]

The following identities were defined in layer0-types and removed from layer0-types during WG LC with the intention to further develop their definitions in the layer0-types-ext:

  identity layer0-bandwidth-type {
    description
      "Bandwidth type carried by a single wavelength channel";
    reference
      "ITU-T G.709: Interfaces for the Optical Transport Network";
  }

  identity bw-otu1 {
    base layer0-bandwidth-type;
    description
      "OTU1 (2.66G)";
  }

  identity bw-otu1e {
    base layer0-bandwidth-type;
    description
      "OTU1e (11.04G)";
  }

  identity bw-otu1f {
    base layer0-bandwidth-type;
    description
      "OTU1f (11.27G)";
  }

  identity bw-otu2 {
    base layer0-bandwidth-type;
    description
      "OTU2 (10.70G)";
  }

  identity bw-otu2e {
    base layer0-bandwidth-type;
    description
      "OTU2e (11.09G)";
  }

  identity bw-otu2f {
    base layer0-bandwidth-type;
    description
      "OTU2f (11.31G)";
  }

  identity bw-otu3 {
    base layer0-bandwidth-type;
    description
      "OTU3 (43.01G)";
  }

  identity bw-otu3e1 {
    base layer0-bandwidth-type;
    description
      "OTU3e1 (44.57G)";
  }

  identity bw-otu3e2 {
    base layer0-bandwidth-type;
    description
      "OTU3e2 (44.58G)";
  }

  identity bw-otu4 {
    base layer0-bandwidth-type;
    description
      "OTU4 (111.80G)";
  }

  identity bw-otucn {
    base layer0-bandwidth-type;
    description
      "OTUCn (beyond 100G)";
  }

Although during WG LC it has been clarified that there is no need/value to define a layer0-bandwidth-type, the OTU identities might still be needed for other purposes to indicate the type of digital client of an OTSiG.

This needs further investigation. May depend on the model used to setup connectivity services over a DWDM network and/or on the 3R model.
