FiberGateway
the PON network. FiberGateway equipments have the ability to deliver the Voice service over two types
of interface:
2.4.1.4.2 Logical interface (VLAN encapsulation)
If the FiberGateway has no FXS ports and the VoIP service is transparently forwarded from the OLT up
to the Home Gateway (and vice versa) within a previously defined voice VLAN. FiberGateway respects
the defined priority and implements the traffic encapsulation from its own Ethernet interface into a
specific T-CONT/GEM-Port over the PON interface and up to the OLT equipment.
2.4.1.4.3 Physical interface (FXS ports)
The FiberGateway has physical RJ11 FXS interface. In this version of the FiberGateway equipment,
voice interface is terminated in the equipment by means of FXS (RJ11) connections. The RJ11 analog
terminals adapter function is auto/self-configured, integrated (analog/VoIP) and associated with a
defined SIP or Megaco (H.248) user.
The FiberGateway will allow VoIP or NGN (Next Generation Network) traffic from devices connected to
the RJ11 or RJ45 interfaces, towards the same internal VLAN.
Apart of the SIP and Megaco (H.248) self-configuration, it is also possible to make modifications in the
voice service configurations by updating the FiberGateway SW through download from the OLT via
OMCI.
The FiberGateway equipment has a DHCP client to get an IP address, alternatively the FiberGateway
could be configured with a static IP. The configuration of the static IP or DHCP client is related to the
WAN side and is enabled by the OLT.
2.4.1.5 WI-FI
FiberGateway circuit block diagram is presented in the figure bellow showing all oscillators in the device
and its frequencies, Figure 8. Intentional radiators in the circuit and radio signal path between circuit
blocks are also shown.
