Figure 8 – 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 an electric one;
Processor (PON chip) which converts Ethernet and GPON interfaces;
A device with factory (initial) settings have the following logical blocks (see Fig.8):
Br0;
Voice (VoIP block);
eth0…1;
FXS0;
IPInterface1.
Br0 blockhere is used to combine LAN ports into a single group.
The eth0..1 blocks physically represent Ethernet ports with RJ-45 connector for connection of PC, STB, or
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.).
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.
IPInterface1 blockis a logical entity on which IP address providing the access in LAN and DHCP server
distributing addresses to clients are located.
