The Draytek Vigor 2820VSn is the Wireless-N Voice over IP (VoIP) and ISDN version of the from the Draytek Vigor 2820 series routers, DrayTek's latest premium ADSL and broadband router/firewall family, featuring an entirely new stylish case design and new DrayOS 3 operating system. Packed with features, it offers truly comprehensive ADSL connetivity and security. Compatible with all variants of ADSL (include ADSLMax and ADSL2+) can also be used for cable-modem and leased line applications thanks to its additional WAN port (Ethernet). A Gigabit Ethernet port on the WAN side provides high speed connectivity for your server (or uplink to a larger Ethernet Switch). The 2820VSn model supports the IEEE 802.11n (Draft 2.0) specification.
The Vigor 2820VSn is similar to the Vigor 2820Vn, except the addition of two ISDN ports. The ISDN interface connects to any compatible ISDN2e service andcan provide either primary internet connection or Dial-up backup for your primary ADSL connection. The Vigor 2820VSn also features an analogue telephone port for VoIP services. (All other features of the Vigor 2820Vn, are supported). For WAN-Failover, you can select either ISDN, 3G modem or Ethernet WAN port.
ISDNThe Vigor 2820VSn features two ISDN interfaces which provide connectivity to ISDN BRI lines (ISDN2e, BT Highway) for Internet access (either primary or backup) and also an internal S0-Bus for connection of ISDN digital telephone sets. Even without an external ISDN line, this gives you additional VoIP telephone capacity as both ISDN ports can be configured as internal buses with two phones connected to each port (each ISDN S0 bus is full 2B+D).
Voice-over-IP Features The Vigor 2820VSn has an analogue phone port and an analogue line port to provide full PSTN and VoIP integration on the same phones, via both the Internet and your regular analogue line. If you have an ISDN phone, you can also use that on the unit's 'Internal S0-Bus' to make additional VoIP phone calls.
The analogue 'Line' port connects into your regular analogue line (PSTN/POTS). This then gives any connected telephones (Analogue or IP) access to your analogue line and allow you to make calls over PSTN or VoIP (you can select the PSTN line instead of VoIP by dialling #0). Incoming calls are automatically switched through to your telephone(s) (either one or both) so that each phone can be used for both VoIP and POTS calls. Both telephones plugged into your router have access to VoIP and your analogue line. In addition, using the 'Digit-Map' facility you can set rules about particular call destinations using either the POTS line or your SIP/VoIP service. For example, local calls can be routed via your PSTN line (if you have a free calls package for example) whereas international calls can go via your preferred VoIP provider; there is flexibility to have several digit-map rules.
3G Data FunctionThe USB port can be used for a compatible 3G modem or a shared compatible printer connection. The secondary WAN Port ('WAN2') can be used for connection to any Ethernet feed for load balancing or Internet backup. You cannot use both WAN2(Ethernet) and USB for 3G at the same time.
