Summary：Recommendation ITU-T G.984.4 provides the optical network termination (ONT) management and control interface (OMCI) specification for gigabit-capable passive optical network (G-PON) systems as defined in Recommendations ITU-T G.984.2 and G.984.3.
Firstly, it specifies the managed entities of a protocol-independent management information base (MIB) that models the exchange of information between the optical line termination (OLT) and the optical network termination (ONT). In addition, it covers the ONT management and control channel,
protocol and detailed messages. This revised version incorporates the material from Amendment 1 (2005), Amendment 2 (2006), and Amendment 3 (2006).
In addition to the purely editorial collection work, this revision endeavours to remove all references to the optional ATM transport capabilities of G-PON, since all modern systems do not support it.
