GPON ONT

2.3 Interoperability

The ONT gateway family equipment complies with ITU-T G.984.x. Recommendation as like as G.984.4 (OMCI) ensuring multi-vendor OLT interop-
erabily with major GPON OLT vendors, as defined in BBF.247 ONU certification program.
BBF.247 ONU certification program certifies ONT link layer configuration and management protocol, OMCI, Figure 2-2, as defined by ITU-T G.984.3,
ITU-T G.984.4 and ITU-T G.988.
IP-based services configuration and management is achieved by means of the TR-069 protocol as defined by Broadband Forum. This procedure
takes for granted that previously the link layer connectivity has been achieved.
TR-069 is then transparent to the OLT, since the TR-069 connections are established between the ACS and the ONTs, Figure 2-4.
ONT gateway family equipments integrate gateway functionalities. Link layer configuration and management is achieved by the use of OMCI,
while IP-based services (RG functionality and Voice over IP) are configured and managed by TR-069, Figure 2-3.
