     Abstract
     
     IANA has defined an "OTN Signal Type" subregistry to the
     "Generalized Multi-Protocol Label Switching (GMPLS) Signaling
     Parameters" registry. This subregistry does not specify Expert
     Review or Private ranges. This draft proposes changes to OTN Signal
     Type subregistry to include Expert Review and Private ranges.

     1. Introduction
     
        With the evolution and deployment of Optical Transport Network
        (OTN) technology, it is necessary to support additional signal
        types ODU1e, ODU3e1 and ODU3e2 mentioned in [G.Sup43]. However,
        as these signal types are only defined in an ITU-T supplementary
        document, IANA cannot allocate values from the "Standards
        Action" range [RFC5226].
     
        IANA maintains "OTN Signal Type" subregistry to the "Generalized
        Multi-Protocol Label Switching (GMPLS) Signaling Parameters"
        registry for the OTN signal defined in [RFC4328] and [RFC7139].
        However, this subregistry does not specify Expert Review or
        Private ranges. This draft proposes changes to OTN Signal Type
        subregistry to include Expert Review and Private ranges.

     2. IANA Considerations
     
        IANA has defined an "OTN Signal Type" subregistry to the
        "Generalized Multi-Protocol Label Switching (GMPLS) Signaling
        Parameters" registry. This document modifies OTN Signal Type
        subregistry by including the following ranges for Expert Review
        and private use. Both ranges come from the "Unassigned" value
        space in [RFC4328] and [RFC7139].
     
        The registry is modified as follows:
     
              Value    Signal Type                           Reference
     
              -----    -----------                           ---------
     
              23-229   A range assigned under the         [This draft]
                       "Unassigned" policy described
                       in [RFC5226].
              230-234  A range assigned under the         [This draft]
                       "Experimental" policy described
                       in [RFC5226].
              235-239  A range assigned under the         [This draft]
                       "Private Use" policy described
                       in [RFC5226].
              240-255   A range assigned under the         [This draft]
                       "Unassigned" policy described
                       in [RFC5226].
