Summary:
|
Recommendation ITU-T G.984.3 describes the transmission convergence layer for gigabit-capable passive optical networks - a family of flexible access networks capable of providing a range of broadband and narrow-band services, operating at the rates of 2.48832 Gbit/s downstream and 1.24416 or 2.48832 Gbit/s upstream. This Recommendation includes the specifications of the following:
-gigabit PON transmission convergence (GTC) layer framing;
-upstream time division multiple access mechanism;
-physical layer operation, administration and maintenance (OAM) messaging channel;
-principles and signalling mechanism of the upstream dynamic bandwidth assignment;
-optical network unit (ONU) activation method;
-forward error correction;
-security.
This Recommendation forms an integral part of the G.984-series of ITU-T Recommendations that, together, specify a single coherent set of access transmission systems.
The present Amendment provides necessary extensions to support Class D ODN.
