CHAPTER 2. OVERVIEW
General Information
The DPN-1021G device is a GPON ONT VoIP gateway with one GPON port, one
10/100/1000Base-T port, one 10/100Base-TX port, and one FXS port.
The gateway DPN-1021G provides an optical line connection to a GPON OLT device. The key
advantage of GPON technology is extraordinary bandwidth of the channel. This helps to deliver the
next generation of high-speed Internet services to home and office users. DPN-1021G helps to
provide a reliable, long-reaching last-mile connection by extending the high-bandwidth public
network to people living and working in remote multi-unit buildings.
High-speed broadband access with the rate up to 2.4Gbps allows to provide customers with all highdemand services (such as HD IPTV, VoIP, Internet connection) simultaneously.
Also the device is equipped with an FXS port which allows connection of an analog phone for calls
via Internet.
Any Ethernet port of the device can be configured to connect to a private Ethernet line.
The VoIP gateway DPN-1021G includes a built-in firewall. The advanced security functions
minimize threats of hacker attacks, prevent unwanted intrusions to your network, and block access
to unwanted websites for users of your LAN.
In addition, the gateway supports IPsec and allows to create secure VPN tunnels.
Built-in Yandex.DNS service protects against malicious and fraudulent web sites and helps to block
access to adult content on children's devices.
You can configure the settings of the gateway DPN-1021G via the user-friendly web-based
interface (the interface is available in two languages – in Russian and in English).
DPN-1021G itself checks the D-Link update server. If a new approved firmware is available, a
notification will appear in the web-based interface of the device.
The built-in TR-069 client allows to perform remote configuration and diagnostics of the device
independently from the customer.

Installation and Connection
Connecting to PC
!
I nvisible laser radiation may be emitted from the end of the fiber and/or from DPN-1021G .
Take all necessary precautions to avoid unnecessary exposure to this radiation.
1. Connect an Ethernet cable between the Ethernet port of your PC and the 10/100/1000Base-T
port (LAN1) or 10/100Base-TX port (LAN2).
2. To connect the device to a fiber optic line: connect the fiber optic cable to the PON port in
the bottom panel of the gateway. Make sure that center conductor of the cable is inserted
directly into the center of the PON connector. Secure the cable by carefully pushing the fiber
connector onto the PON connector until tight. Be careful not to over-tighten the connector or
you may damage either the cable or the device.
3. To connect the device to an Ethernet line: in the web-based interface of the gateway, select
the gateway's LAN port that will be used as the WAN port and create an Ethernet WAN
connection. Then connect an Ethernet cable between an available Ethernet port of the
gateway and the Ethernet line.
!
Please connect the gateway to the ISP's Ethernet line only after setting the WAN port and
creating the Internet connection.
4. Connect a phone cable between the FXS port of the gateway and the phone.
5. Connect the power cord to the power connector port on the back panel of the gateway, then
plug the power adapter into an electrical outlet or power strip.
6. Turn on the gateway by pressing the ON/OFF button on its back panel.
7. Wait for several minutes. When the device receives all needed settings, the GPON LED will
stop blinking and will light solid green. When the Internet connection is established, the
Internet LED will light solid green.

Statistics
The pages of this section display data on the current state of the gateway:
• network statistics
• statistics for the PON interface
• IP addresses leased by the DHCP server
• the routing table
• data on devices connected to the gateway's network and its web-based interface
• addresses of active multicast groups
• active sessions.
On the Statistics / Network Statistics page, you can view statistics for all connections existing
in the system (WAN connections, LAN). For each connection the following data are displayed:
name and state (when the connection is on, its name is highlighted in green, when the connection is
off, its name is highlighted in red), IP address and subnet mask, gateway (if the connection is
established), MAC address, and volume of data received and transmitted (with increase of the
volume the units of measurement are changed automatically: byte, Kbyte, Mbyte, Gbyte).
Figure 16. The Statistics / Network Statistics page.
To view detailed data on a connection, click the line corresponding to this connection.
