1. A network control method for use with a communication network in which a node serving terminal (NST) communicates optical signals multiplexed by wavelength division multiplexing (WDM) with an end node via a fiber optic cable, the method comprising:

  • determining a highest number N of separable channel wavelengths at the end node;

    limiting a number of channel wavelengths actually used in communication employing WDM with the end node via the fiber optic cable to said number N; and

    selecting a group of N channel wavelengths for use in communication with the end node via the fiber optic cable according to at least one of the following;

    predetermined criteria;

    an arbitrary selection; and

    an expected acceptable communication performance.
