The TR-069 client block is used for device remote control with the help of the ACS server (Auto
Configuration Server) via TR-069 protocol. The block is used to establish communication between ACS and
subscriber’s equipment, process ONT queries, and configure services.
The WANConnectionDevice block is an object associated with WAN interface. It is an interim interface
between the OMCI and RG parts of the device.
The veip 0.n blocks are WAN interfaces of the device’s router; each of the interfaces is used to provide a
certain type of services. In this example:
– veip0.1 is for the Internet;
– veip0.2 controls the multicast traffic;
– Veip0.3 provides VoIP services;
– veip0.4 provides VPN service on a separated port;
– veip0.5 provides other services (alarm system);
– veip0.6 provides VoD and IPTV on STB.
These WAN interfaces have the following operation modes:
– PPPoE—starts PPP client;
– IPoE DHCP—starts DHCP client;
– IPoE Static—uses a static address;
– Bridging—operates in the bridge mode.
The bri blocks are the objects of the 2nd level and operate as bridges between the LAN and WAN
interfaces to include the interface into one group. The br1 block is connected to the veip0.1 interface, which
operates in the PPPoE mode, and to the eth0 port. The br4 block operates in bridge + DHCP mode in order to
use the address of this interface for SIP client (Voice block). The br2, br5,br6 blocks operate as a bridge, which
allows transparent traffic transmission to the LAN ports of the router.
The eth0...3 blocks represent LAN interfaces for connection of subscriber’s equipment.
