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 dened in BBF.247 ONU certication program.
BBF.247 ONU certication program certies ONT link layer conguration and management protocol, OMCI, Figure 2-2, as dened by ITU-T G.984.3,
ITU-T G.984.4 and ITU-T G.988.
Figure 2-2: Link Layer Conguration and Management
IP-based services conguration and management is achieved by means of the TR-069 protocol as dened 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 conguration and management is achieved by the use of OMCI,
while IP-based services (RG functionality and Voice over IP) are congured and managed by TR-069, Figure 2-3.
