• 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
page 106
and VDSL connection is not available, then the ADSL2+ will automatically be the network
interface.
• 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 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

the SBG3500-N'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.
