ITU-T G.988 PDF

This Recommendation specifies the optical network unit (ONU) management and control interface (OMCI) for optical access networks as defined in [ITU-T G.984.x], [ITU-T G.986], [ITU-T G.987.x] and potentially others.

The OMCI specification addresses ONU configuration, fault management and performance management for optical access system operation, and for several services including:

• GEM adaptation layers;

• Ethernet services, including MAC bridged LAN;

• circuit emulation service;

• voice services.

This Recommendation defines a protocol necessary to support the capabilities identified for these ONUs. It also allows optional components and future extensions.
