2.2 Typical Network Applications
This topic describes the typical network applications of the HG8010/HG8110/HG8240/
HG8245/HG8247/HG8447.
As a network terminal, the HG8010/HG8110/HG8240/HG8245/HG8247/HG8447 is deployed
at the GPON access layer and connects home users and SOHO users to the Internet through
optical upstream ports. On the local area network (LAN) side, the HG8010/HG8110/HG8240/
HG8245/HG8247/HG8447 provides abundant hardware ports to meet various network
requirements of home users and SOHO users.

l
In the upstream direction, the HG8010 is connected to the optical splitter and the network-
side OLT through the passive optical network (PON) port, namely the OPTICAL port, to
provide integrated access services.
l
In the downstream direction, the HG8010 is provides a 10/100/1000M Base-T Ethernet
port for connecting to a home gateway. The home gateway then can be connected to a PC,
STB, or video phone to provide high-speed data and video services.

In the upstream direction, the HG8110 is connected to the optical splitter and the network-
side OLT through the passive optical network (PON) port, namely the OPTICAL port, to
provide integrated access services.
l
In the downstream direction, the HG8110 is connected to various terminals through the
following LAN-side ports to implement the triple play service:
–
One 10/100/1000M Base-T Ethernet ports, which can be connected to terminals such
as PCs, STBs, and video phoned to provide the high-speed data and video services.
–
One TEL ports, which can be connected to telephone sets or fax machines to provide
superior and cost-effective voice over IP (VoIP), fax over IP (FoIP), and modem over
IP (MoIP) services.
