    "This model describes configuration and operational state data
    for an optical transport line system node, or ROADM (incl. CDC
    ROADMs, WSS, Dynamic Gain Equalizer/DGE).

    Nodes are modeled as a configurable switching element with
    ingress and egress ports, as well as a number of add/drop ports
    that can be set up to direct portions of the optical spectrum
    to the appropriate degrees.";
