Thank you for choosing the D-Link DG-102S, the value leader for VoIP products.
The D-Link DG-102S VoIP Station Gateway links traditional telephony networks to IP
networks with conventional telephony devices such as analog phones or fax machines. The
DG-102S includes two loop start Foreign Exchange Subscriber (FXS) interfaces with normal
RJ-11 telephone connectors that provide voice/fax communication over the IP network, and it
also provide two 10/100 Mbps dual speed Ethernet ports. One Ethernet port is for a
DSL/Cable Modem or other WAN devices, and the other is for connection to create a home or
small office LAN networks. The built-in DHCP server/client and Network Address
Translation (NAT) function automatically assign IP address for LAN users, allowing
multiple users to share a single Internet connection. It can be configured/monitored via the
Console, Web browser or Telnet and SNMP management is also supported.
By routing calls over the Internet or any IP network, this gateway can reduce or eliminate
long distance or inter-office phone charges. Corporations can also enjoy the benefits of
network consolidation and reduction of leased lines by relying on the Internet service
providers to deliver toll-quality voice communications over the IP networks.
