DSR Series
Unified Services Routers
D-Link Unified Services Routers provide secure,
high-performance networking solutions to address
the growing needs of small and medium businesses.
The integrated high-speed IEEE 802.11n wireless
technology in the DSR-150N, DSR-250N, DSR-500N,
and the DSR-1000N routers offers comparable
performance to traditional wired networks, but
with fewer limitations. Each router provides optimal
network security via features such as Virtual Private
Network (VPN) tunnels, IP Security (IPSec), Point-to-
Point Tunneling Protocol (PPTP), Layer 2 Tunneling
Protocol (L2TP), and Secure Sockets Layer (SSL).
These routers also allow you to empower your road
warriors with clientless remote access anywhere
and anytime using SSL VPN tunnels.
Comprehensive Management Capabilities
The DSR-500/500N and DSR-1000/1000N include dual-
WAN Gigabit Ethernet that provides policy-based
service management to ensure maximum productivity
for your business operations. The failover feature
maintains data traffic without disconnecting when
a landline connection is lost. The Outbound Load
Balancing feature adjusts outgoing traffic across two
WAN interfaces and optimizes system performance,
resulting in high availability. The second WAN port
can be configured as a DMZ port, allowing you to
isolate servers from your LAN.
Superior Wireless Performance
The DSR-150N, DSR-250N, DSR-500N, and DSR-1000N
include 802.11a
2
/b/g/n, allowing for operation on
either the 2.4 GHz or 5 GHz
2
wireless LAN radio bands.
Multiple In Multiple Out (MIMO) technology allows the
DSR-150N, DSR-250N, DSR-500N, and DSR-1000N to
provide high data rates and a wide wireless coverage
area with minimized “dead spots.”
Flexible Deployment Options
The DSR Series supports Third Generation (3G)
networks via an extendable USB 3G dongle
4
. This
3G network capability offers an additional data
connection for critical or backup services. For the
DSR-1000/1000N, a 3G USB dongle can be configured
as a third WAN port, performing Traffic Load Balancing
and executing automatic failover whenever the
primary WAN link gets lost. For the DSR-500/500N,
5
the second WAN port could be a dedicated WAN2
or 3G dongle, performing Traffic Load Balancing and
executing automatic failover whenever the primary
WAN link gets lost. For the DSR-150/150N/250/250N,
5
the 3G dongle could be configured as a backup link
when the primary WAN link is down or configured as
the primary WAN port.
Robust VPN Features
A fully featured virtual private network (VPN) provides
your mobile workers and branch offices with a
secure link to your network. The DSR-150/150N, DSR-
250/250N, DSR-500/500N, and DSR-1000/1000N are
capable of simultaneously managing 1, 5, 10, or 20
Secure Sockets Layer (SSL) VPN tunnels respectively,
empowering your mobile users by providing remote
access to a central corporate database. Site-to-
site VPN tunnels use IP Security (IPSec) Protocol,
Point-to-Point Tunneling Protocol (PPTP), or Layer 2
Tunneling Protocol (L2TP) to facilitate branch office
connectivity through encrypted virtual links. The
DSR-150/150N simultaneously supports up to 10
IPSec VPN tunnels plus 10 additional PPTP/L2TP
tunnels. The DSR-250/250N, DSR-500/500N, and
DSR-1000/1000N simultaneously support up to 25,
35, and 70 IPSec VPN tunnels respectively, and 25
additional PPTP/L2TP tunnels.
Efficient Green Technology
D-Link Green Wi-Fi and D-Link Green Ethernet
features save power and help cut energy usage
costs. The D-Link Green WLAN Scheduler shuts
down your wireless network automatically according
to a schedule you define, allowing you to turn off
your wireless network during off-peak hours, saving
energy and keeping your network secure. The D-Link
Green Ethernet feature can detect if a link is down on
a port, and automatically puts that port into a sleep
mode that drastically reduces the amount of power
used. In addition, compliance with RoHS (Restriction
of Hazardous Substances) and WEEE (Waste
Electrical and Electronic Equipment) directives make
D-Link Green-certified devices an environmentally
responsible choice.
