Users can now make voice calls over the internet without difficulties. Its high performance voice DSP provides exceptional voice quality with adaptive jitter buffer and long G.168 echo tail. A WAN Ethernet port connects the DVG-5102SP to the Internet via a broadband modem (cable, DSL), and a LAN Ethernet port is available to provide connectivity and router/firewall functionality for sharing the Internet connection with your computers. The DVG-5102SP supports prioritized voice traffic for optimum Quality of Service (QoS) Specification: Key Components / Performance CPU MPS4200/170MHz/MIPS-32 DSP LSI ZSP400/110MHz SDRAM/ Flash 166MHz/ 8MB Port Functions WAN 1. 1*10/100 BaseT ports 2.
