The Vigor2820 is an ADSL2+ router with 2nd Ethernet WAN. This 2nd WAN can connect
to DSL/Cable modem or fiber media converter for policy-based load-balance, fail-over
and BoD (Bandwidth on Demand); it also features advanced bandwidth control
mechanism such as IP-layer QoS, NAT Session Limitation, Bandwidth Borrowed, etc., to
allow easy, flexible, reliable access control and bandwidth management.
The SPI (Stateful Packet Inspection) firewall uses object-based design to make settings of
firewall policies easy. The CSM (Content Security Management) feature allows more
precise and efficient access control for URL/Web Content Filtering, IM (Instant
Messenger) and P2P (Peer to Peer) applications.
With hardware-based implementation of the VPN protocols, the Vigor2820 supports up to
32 VPN tunnels using advanced protocols such as IPSec/PPTP/L2TP/L2TP over IPSec
with AES/DES/3DES for encryption and MD5/SHA-1 for authentication.
Vigor2820 ‘n’ models comply with 802.11n Draft-n standards. They support
WEP/WPA/WPA2 encryption and MAC Address Control, Wireless LAN Isolation, and
802.1X authentication. The Wireless Rate Control function can adjust the data rate of
each wireless station (client).
Vigor2820 ‘V’ models provide twin analogue phone and one line port. ‘S’ models also
support twin ISDN ports that one is fixed as ISDN S0 port for ISDN phone and the other
is configurable for ISDN line and phone. It supports multiple SIP registrars with high
flexible configuration and call handing options.

Below shows the names that displayed on front panel of the device and the WEB UI of
this device.
ISDN TE (Terminal Equipment) means an interface for transmitting analog signal
through Internet between Switching and router. Such interface is also named with ISDN
S0 extern in Germany.
ISDN NT (Network Terminator) is a port that used to connect general phone. Such
interface is also named with ISDN S0 intern in Germany.
The Phone S0 port on Vigor2820 series is fixed to connect phone forever and the LED on
the connecter will light orange always. However ISDN/Phone S0 port on this device is
configurable for connecting phone or accessing Internet according to the settings that you
adjust on WEB UI (please refer to VoIP>>Phone Setting for detailed information).
Warning: When the orange LED lights (means ISDN NT mode), the ISDN
port can be used to connect phone only. Wrong ISDN connection might cause
severe damage on your device.

Before starting to configure the router, you have to connect your devices correctly.
1. Connect the ADSL interface to the external ADSL splitter with an ADSL line cable
for all models. For Vigor2820Vn/VS/VSn, also connect Line interface to external
ADSL splitter.
For second WAN, connect the cable Modem/DSL Modem/Media Converter to
WAN2 port of router with Ethernet cable (RJ-45).
2. Connect one end of an Ethernet cable (RJ-45) to one of the LAN ports of the router
and the other end of the cable (RJ-45) into the Ethernet port on your computer.
3. Connect the telephone sets with phone lines (for using VoIP function). For the model
without phone ports, skip this step.
4. Connect one end of the power adapter to the router’s power port on the rear panel,
and the other side into a wall outlet.
5. Power on the device by pressing down the power switch on the rear panel.
6. The system starts to initiate. After completing the system test, the ACT LED will
light up and start blinking.
(For the detailed information of LED status, please refer to section 1.1.)

Caution: Each of the Phone ports can be connected to an analog phone only. Do not
connect the phone ports to the telephone wall jack. Such connection might damage your
router.

Such information is provided for Vigor2820 S models (e.g., Vigor2820VS/VSn).
Phone S0 is always fixed to connect ISDN phone. However, ISDN /Phone S0 is
configurable as NT or TE mode. When the user configures ISDN /Phone S0 as NT mode
in VoIP>> Phone Settings, the orange LED will light on to indicate ISDN-NT is
selected. And by using ISDN phone adapters (coming from the router package), the user
can connect several phones to Vigor2820VS for communication. Refer to the following
figure for reference.

15
Yet, if the user configures ISDN / Phone S0 as TE Mode in VoIP>> Phone Settings, the
green LED will light on to indicate ISDN-TE is selected. Then, the port is specified for
ISDN line only. Refer to the following figure for reference.

Windows XP/2000. For Windows 98/SE, please visit www.draytek.com.
Before using it, please follow the steps below to configure settings for connected
computers (or wireless clients).
1. Connect the printer with the router through USB/parallel port.
2. Open Start->Settings-> Printer and Faxes.
