About the Vanguard 340 and 340 Enhanced
Target Applications
Vanguard 340 and 340 Enhanced DSL and G.SHDSL
DSL/Cable Modem
The Vanguard 340, and 340 Enhanced support connectivity to high-speed broadband
services such as DSL and Cable by connecting the 10/100BaseT port on the
Vanguard 340 Enhanced to the Ethernet port on the DSL or Cable modem.
Cable modem speeds vary in the downstream direction. Network speeds can reach
27 Mbps., but this is an aggregate amount of bandwidth that is shared by users. Few
computers will be capable of connecting at such high speeds, so a more realistic
number is 1 to 3 Mbps. In the upstream direction speeds can be up to 10 Mbps. Most
modem producers have selected a more optimum speed between 500 Kbps and 2.5
Mbps.
