Description: Band Plan. The band plan is a way of selecting a mapping between channels and wavelengths/frequencies. The selected band plan should correspond to the band plan on the line system. The band plan is used to automatically select the next wavelength or frequency for newly installed Waveservers based on the member-id assigned to the device. Modifying Band plan will have an effect on PTP attributes. Software will automatically assign a per-defined PTP Wavelength, Frequency, and Channel combination from selected Band Plan. Note that the automatic reassignment will only occur when a valid Band Plan is already provisioned (i.e. existing Band Plan is not equal to None), the existing PTP Wavelength, Frequency, and Channel have value of zero, and user provisions Member ID from 0 to a non-zero value (i.e. from 'uncommisioned' state to 'commissioned' state) that's within the maximum wavelength allocation specified in the Band Plan (each Member ID reserves two wavelengths) . Software shall automatically update existing channel number provisioning when user changes Band Plan provisioning. Channel number shall be set to 0 if provisioned wavelength/frequency is not found in the new Band Plan or the new Band Plan equals to None.
