• ADSL2+ and VDSL, connect the DSL1 and/or DSL2 port using a phone cable to a DSL or MODEM
on a splitter or your telephone jack. For single DSL connection, use only DSL1 port. For DSL
bonding connection, use both DSL1 and DSL2 port at the same time. Refer to Section 6.2 on
page 104 for the Network Setting > Broadband screen. When using the DSL1/DSL2 ports
and VDSL connection is not available, then the ADSL2+ will automatically be the network
interface. You need to enable bonding feature if you want to use the bonding state. See (Section
6.5 on page 119) for details.
• DSL and GbE, connect the DSL port to the DSL or MODEM as described above and connect the
GbE port to a broadband router (if available) using an Ethernet cable. The 3G USB dongle is the
failover or a backup connection in case both the DSL and GbE fails. You can set the load balance
and failover in SBG3500-N Series to prioritize and redirect all traffic to the backup connection in
case the Internet access is down by clicking Network Settings > Broadband > Multi-WAN
• DSL and Fiber (SFP), connect the the DSL port to the DSL or MODEM and connect the SFP port
using a Fiber Optical module, also known as a mini-GBIC transceiver, to a Switch or Router. The
3G USB dongle is the failover or backup connection. Set load balance as described above and see
the SBG3500-N Series’s Quick Start Guide for details on how to install and remove a mini-GBIC
transceiver.
• DSL and 3G, connect the DSL port to the DSL or MODEM and connect the USB port using a USB
3G dongle. The Fiber/Ethernet is the failover. You can set the load balance/failover as described
above.
• Fiber and 3G, connect the SFP port using a mini-GBIC transceiver and the USB port using a USB
3G dongle as described above. The DSL is the failover in case both Fiber and 3G is unavailable.
• GbE and 3G, connect the GbE port to a broadband router and the USB port using a USB 3G
dongle. The DSL is the failover in case both Fiber and 3G is unavailable.
• WLAN or Wireless Internet access, Refer to Section 1.2.2 on page 20 for more information.
