2.3 Interoperability
XGS-PON Fiber Gateway equipment complies with ITU-T G.9807.1 recommendation and G.988 (OMCI)
ensuring multi-vendor OLT interoperability with major 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, as defined by ITU-T G.988.
Figure 2: Link Layer Configuration and Management
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 4.
Fiber Gateway 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 3.
