l In the upstream direction, the HG8245 is connected to the optical splitter and the network-
side OLT through the PON port, namely the OPTICAL port, to provide integrated access
services.
l In the downstream direction, the HG8245 is connected to various terminals through the
following LAN-side ports to implement the triple play service:
– Four 10/100/1000M Base-T Ethernet ports, which can be connected to terminals such
as PCs, STBs, and video phones to provide the high-speed data and video services.
– Two TEL ports, which can be connected to telephone sets or fax machines to provide
superior and cost-effective VoIP, FoIP, and MoIP services.
– Two Wi-Fi antennas, which can connect to Wi-Fi terminals wirelessly to provide a
secure and reliable high-speed wireless network.
– One USB port, which can be connected to a USB storage device to provide convenient
storage and file sharing services within a home network.
