|1. ADSL Compatibility
|Vigor2820 ISDN S0 Series is not only a security ADSL2/2+ router for SOHO but also makes telephoning over the Internet as convenient as you can.
|Dual WAN Load Balancing / Fail Over|
|VPN Firewall Application|
|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. Object-based firewall is flexible and allows your network be safe. DoS/DDoS prevention and URL/Web content filter strengthen the security outside and control inside.
|Vigor2820VSn is Wi-Fi certified and supports WMM (Wi-Fi multimedia). It can keep the priority of voice, video and audio applications in a Wi-Fi network. The bandwidth allocated for video, and when traffic conditions fluctuate or change, the video traffic will maintain its allocated bandwidth, whereas the remaining bandwidth is shared by non-priority traffic. While watching the video, you are less likely to see slow action. WMM lowers the priority of other network traffic which is not time-critical-such as large file downloading.
|VoIP Application / ISDN (S0) Application|
|Phone S0 port is dedicated for ISDN phone while the ISDN/Phone S0 port is configurable for ISDN line, or ISDN phone if required. It can support multiple SIP registrars with high flexible configuration and call handling options. The analogue fax machine or conventional analogue phone can be attached to phone port (FXS port). You can connect your regular analogue line to the Line port of Vigor2820VSn. While you enable VoIP facility, you still can access fixed line (analogue line) to make calls just by dialing #0. Furthermore, you can set rules through "Digit Map" function about particular call destinations using either your SIP/VoIP service or the PSTN line or the ISDN line. e.g. you can route local calls via your PSTN/ISDN line (if you have a free calls package) whereas international calls can go via your preferred VoIP provider; there is flexibility to have several digitmap rules. You can make economical phone calls over the Internet with VoIP, or over analog phone line or the ISDN line.
|CSM / 3.5G Fail-over Backup|
|Vigor2820 series' CSM (Content Security Management) function can block selected P2P and instant message applications. This would not only help employees stay focused on their job but also prevent possible treats from those applications damaging corporate essential data severs.
3.5G fail-over backup can keep business continuous during a downtime of the leased line from ISP.
