Description: Wavelength value setting of the ptp, in nm. This is the configured wavelength value. Wavelength value cannot be modified while Admin State is set to enabled, except when changing from zero value to another value. It also cannot be modified if the PTP XCVR type is not a modem. Wavelength cannot be modified in the same operation as Frequency, Channel, and Wavelength Spacing, only one of those fields may be modified in a single operation. If Wavelength is modified, Frequency and Channel will be automatically updated to valid values. Modification to this field will be validated against the Wavelength Spacing field. In the case of automatic wavelength assignment, if Member ID = n, Port 1 PTP Channel = (n * 2 - 1), P12 PTP Channel = (n * 2). If PTP Wavelength, Frequency, and Channel have non-zero values, automatic wavelength assignment shall be skipped. If user provisions a Member ID that exceeds the maximum wavelength allocation specified in selected Band Plan (e.g. setting Member ID to 45 with Fixed-88 plan), automatic wavelength assignment shall be skipped.
