scope:
This Recommendation specifies the optical network termination management and control interface (OMCI) for the G-PON system defined in [ITU-T G.984.2] and [ITU-T G.984.3] to enable multivendor interoperability between the optical line termination (OLT) and the ONT.
The OMCI specification addresses the ONT configuration management, fault management and performance management for G-PON system operation and for several services, including:
• asynchronous transfer mode (ATM) adaptation layer 5;
• G-PON encapsulation method (GEM) adaptation layers;
• circuit emulation service;
• Ethernet services, including MAC bridged LAN;
• voice services;
• wavelength division multiplexing.
The focus of this OMCI specification is on Fibre to the home (FTTH) and Fibre to the business (FTTBusiness) ONTs; however, support for optical network units (ONUs) is addressed as well. This Recommendation defines a protocol necessary to support the capabilities identified for these ONTs. It also allows optional components and future extensions.
