Hi Denver, I had not looked at this from your perspective before. The remote terminal, as shown in the referenced diagram, does not provide services directly to end users. It is, instead, an intermediate node that in turn feeds the ONUs, which, in turn, support the end users through GR-303 interfaces. Those interfaces can include fiber, as well, as in the case of Marconi's [nee Reltec's] and some other variants (ALA, e.g.).
How do we reconcile this, is the question. Is the DLC architecture conducive to hierarchical (CO/HDT-->RT---ONU-->gr303) building blocks? Am I incorrect in stating that the ONU possesses DLC attributes on its interfaces to the subscriber location? If we regard the term DLC for it's "concentration" features (of the past, mostly), your explanation makes more sense. But if it is not concentrating (in the statistical sense), then I view it only as a large node that supports the ultimate 303 interface-bearing ONU, which supports the next gen DLC attributes. Semantics? or am I all wet here? Please explain.
Come to think of it, if the DLC RT included DSLAM equivalence, then it is a statistical kind of engine, as well. Your serve...
