1.1.1  Internet Access
Your Zyxel Device provides shared Internet access by connecting the DSL port to the DSL or MODEM jack 
on a splitter or your telephone jack. You can have multiple WAN services over one ADSL or VDSL. The 
Zyxel Device cannot work in ADSL and VDSL mode at the same time.
Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you configure in 
the Zyxel Device. Refer to Section 6.2 on page 123 for the Network Setting > Broadband 
screen.
Computers can connect to the Zyxel Device’s LAN ports (or wirelessly).
