Superior voice quality
With Quality of Service (QoS), the DVG-5121SP ensures that voice transmissions over the Internet are at least as good as, if not better than, the voice quality of a conventional telephone connection. The adapter supports useful functions such as caller ID display, 3-way conference, phone book and speed dial. Calling and receiving calls becomes easy.
Internet Sharing
The DVG-5121SP includes a router so you can also surf the Internet. Simply connect the adapter's LAN port to your PC or an Ethernet switch if several computers are to be connected to the Internet. With priority queues, the DVG-5121SP ensures that videos or computer games are transmitted with priority.
Security
The DVG-5121SP supports VLAN for voice transmissions, which are separated from the rest of the data traffic and are tap-proof. The NAT firewall protects your LAN against intruders from the Internet. For access control, the data packets are filtered by the user based on MAC or IP addresses or based on port. The "Child Protection" allows you to block unwanted websites and limit the time of Internet access.
