Linksys One technology is automatic and self configuring simply plug in a Linksys One voice gateway to a Linksys One Services Ethernet switch port and your business is ready to communicate. The VGA2200 provides two FXS ports to connect analog stations to the Linksys One solution. When more than two-station support is required, additional VGA2200 analog voice gateways can be added to the solution. The 10/100 Ethernet port connects the VGA2200 to the site and enables Voice overInternet Protocol (VoIP) calls. This port also accepts IEEE power over Ethernet (802.3af) and fully powers the voice gateway and additionally provides quality of service for each call (DSCP).
