USB Fast Ethernet


The USB LAN ISDN Adapter provides outside-the-box plug- and-play local area network connections for USB-enabled PCs, notebooks and laptops. This adapter uses a B type USB port to connect with the USB host, and an RJ-45 port to connect with a 10/100 Fast Ethernet LAN link. Installation is easy and no external power is required! The network sharing is easier than ever.

ISDN (Integrated Service Digital Network) is the most convenient and economical way to use the existing copper wire for both voice and data communication. Data transmission rate can reach up to 128K. It can not only provides 128K transmission but also allows voice conversation and fast Internet Access simultaneously.
