Descriptions of the ports of the HG8240

OPTICAL HG8240 GPON

Indicates the optical port. The optical port is equipped with a

rubber plug and is connected to an optical fiber for upstream

transmission.

The type of the optical connector connected to the OPTICAL

port is SC/APC.

LAN1-LAN4 Indicate auto-sensing 10/100/1000M Base-T Ethernet ports

(RJ-45), used for connecting to PCs or IP STBs.

TEL1-TEL2 Indicate VoIP telephone ports (RJ-11), used for connecting to

the ports on telephone sets.

ON/OFF Indicates the power-on/power-off button, used for powering on

or powering off the device.

POWER Indicates the power port, used for connecting to the power

adapter or backup battery.

BBU Indicates the external backup battery monitoring port, used for

connecting to the backup battery for monitoring the battery.

RESET

Indicates the reset button. Press the button for a short time to

reset the device; press the button for a long time (longer than

10s) to restore the device to the default settings and reset the

device.

In the upstream direction, the HG8240 is connected to the optical splitter and the networkside

OLT through the passive optical network (PON) port, namely the OPTICAL port, to

provide integrated access services.

l In the downstream direction, the HG8240 is connected to various terminals through the

following LAN-side ports to implement the triple play service:

– Two 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.

– Two 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.
