Figure 7 – Logical Architecture of a Device with Factory Settings
Main Components of the Device:
• Optical receiver/transmitter (SFF module) for conversion of an optical signal into electric one;
• Processor (PON chip) which converts Ethernet and GPON interfaces;
• Wi-Fi modules for wireless interfaces of the device.
A device with factory (initial) settings have the following logical blocks (see Figure 7):
• Br0;
• Voice (IP telephony);
• eth0…3;
• FXS0;
• wl0, wl0.1..wl0.3, wl1, wl1.1..wl1.3;
• IPInterface.
Br0 block here is used to combine LAN ports into a single group.
Eth0..3 blocks physically represent Ethernet ports with RJ-45 connector for connection of PC, STB, and other
network devices. They are logically included into br0 block.
FXS0 block is a port with RJ-11 connectors for connection of analogue phone. It is logically included into the
Voice block. The Voice block can be controlled through web interface or remotely with ACS server via TR-069
standard. The block specifies VoIP service parameters (SIP server address, phone number, VAS, etc.).
Wl0, wl0.1…wl1.3 blocksfor Wi-Fi modules connection. Wl0 blocks are interfaces for 2.4 GHz operation,
wl1ones – for 5 GHz operation.
Filter and Marking blocks enable inclusion of local interfaces into a single group (to br0 block). They deal with
the traffic transmission rules, Filter blocks are responsible for the incoming traffic on the interface, Marking
blocks – for the outgoing one.
IPInterface block is a logical entity on which IP address providing the access in LAN and DHCP server
distributing addresses to clients are located.
