P Pr re ef fa ac ce e
Vigor2820 series is an ADSL and broadband router with WAN interface. It provides
policy-based load-balance, fail-over and BOD (Bandwidth on Demand), also it integrates IP
layer QoS, NAT session/bandwidth management to help users control works well with large
bandwidth.
By adopting hardware-based VPN platform and hardware encryption of AES/DES/3DS, the
router increases the performance of VPN greatly, and offers several protocols (such as
IPSec/PPTP/L2TP) with up to 32 VPN tunnels.
The object-based design used in SPI (Stateful Packet Inspection) firewall allows users to set
firewall policy with ease. CSM (Content Security Management) provides users control and
management in IM (Instant Messenger) and P2P (Peer to Peer) more efficiency than before.
By the way, DoS/DDoS prevention and URL/Web content filter strengthen the security
outside and control inside.
Vigor2820 “S” series models support two ISDN ports. Phone S0 port is dedicated for ISDN
phone and ISDN/Phone S0 port is configurable for ISDN line and phone if required. It can
support multiple SIP registrars with high flexible configuration and call handling options.
Object-based firewall is flexible and allows your network be safe. In addition, through VoIP
function, the communication fee for you and remote people can be reduced.

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 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.
