ITU-T G.989.3 TC layer operating in ITU T G.987.3 or ITU-T G.9807.1 TC layer mode |
|
This supplement describes how a flexible G.989.3 TC layer implementation can be used to support a G.987.3 or G.9807.1 PON.
G.989.3 was largely derived from G.987.3. The G.9807.1 Appendix C TC layer specification was derived from G.989.3, with G.9807.1 Appendix II describing this derivation in detail. G.9807.1 also specifies that a G.9807.1 compliant OLT will interwork with a G.987.3 compliant ONT.
It should be evident from this chain of derivation that a flexible TC layer implementation that supports G.989.3 can support G.9807.1 or G.987.3 operation. This supplement describes the implementation flexibility required.
