2-Port VoIP Station Gateway with Built-in 4-Port Switch
Save Long-Distance Phone Charge
The Gateway receives voice and data services over a single network connection. Expensive long-distance and international phone calls over the ordinary telephone service can be avoided altogether. You make and receive voice calls over the same line that you use to connect to the Internet, and pay the same Internet connection charge, plus a service charge to your Service Provider.
2 FXS Ports
Through a 10/100BASE-TX Ethernet port, the DVG-1402 connects directly to your company network or the broadband line (DSL or cable modem), without going through any PBX. It provides 2 FXS (Foreign Exchange Station) ports (2 RJ-11 phone sockets) for connection to 2 telephone sets or fax machines
You simply plug in any ordinary telephone sets to the phone sockets on the Gateway, then operate your telephone as you normally do. All destination numbers must be registered with your Internet Telephony Service Provider or Proxy Server. You dial your server's code, then your destination number; the Internet Telephony Service Provider or Proxy Server will map your number with the destination.
Guaranteed Voice Quality
The Gateway incorporates Quality of Service (QoS) functions to ensure that voice received is almost the same as that received on the ordinary phone. To allow for a smooth voice reception, voice packets get a higher priority over data packets on the network packet stream. Other capabilities include echo cancellation, silence suppression/comfort noise generation (when there is a prolonged silence), adaptive jitter buffer and lost voice packet recovery.
Built-in Router for Shared Broadband Internet Connection
The Gateway provides built-in router function to permit sharing of the broadband line for Internet access in your office. Built-in NAT and DHCP server functions automatically create an IP address and assigns it for each user, simplifying everyone's logon operation. NAT also provide firewall protection for your network, blocking and redirecting certain ports to limit the services that outside users can access your network.
Built-in 4-Port Ethernet Switch
For LAN connection, the Gateway incorporates 4 10/100Mbps Ethernet ports, providing ready connection for workstations and servers. This saves you the cost and trouble of installing a separate Ethernet switch.
