Lucent Technologies DSL Access Concentrator Stinger FS+ - Manual (Page 3)

• Lowers your cost per port through increased hardware
integration
• Shrinks the equipment footprint by more than 33% over
previous Stinger solutions (50% versus other vendors’
solutions)
• Reduces the need to subtend multiple DSLAMs, translating
to fewer ports in the aggregation network
Lightning-fast switching capacity—Traffic speed is
critically important to the quality delivery of your business
and consumer-oriented multimedia services. By providing
the bandwidth needed to support increased subscriber
densities, the Stinger FS+ more than quadruples its
previous performance levels to real data forwarding
throughput up to 7.2 Gbps. With Gigabit Ethernet and OC-
12 bandwidth to the backbone and enhancements such as
IP multicast, the new Stinger solution enables you to offer
high-speed video and data delivery over DSL.
Some DSL vendors promote backplane capacity figures as
a measure of their DSLAM’s performance. In reality,
switching performance is a factor by which consumable
bandwidth should be measured, since this is the true
determinant of how fast the platform can forward traffic.
The Stinger FS+ utilizes multiple high performance,
minimum delay, redundant ATM and IP switching fabrics
for supporting the highest speed network application
requirements of today. Streaming media applications such
as video and audio require constant data flow, greatly
upping the performance ante for edge aggregation devices.
The FS+ high speed switching fabric is up to the task-built
to handle the requirements of next generation, high
performance services over DSL.
New, intelligent IP Services modules—Stinger now
offers intelligent IP services capabilities and a complement
of end-to-end subscriber solutions. By utilizing the latest in
Stinger’s advanced ATM capabilities and intelligent IP
services, you can cost-effectively and efficiently deploy
more business class and residential multimedia services.
You can offer your customers everything from broadband
voice and data to broadcast and on-demand video
capabilities today.
IP intelligence at the network edge also simplifies
subscriber VC management and reduces the number of
network elements. It enables you to:
• Better utilize your WAN links via edge routing
• Improve network robustness with distributed routing
• Increase your network security
• Add to your network design flexibility
QoS and reliability from blending IP and ATM—By
bringing together both IP and ATM switching on all ports,
the Stinger FS+ enhances the overall QoS by enabling the
fastest local switching between subscriber ports. Also,
high-performance trunk-to-trunk switching means you
can star and/or daisy-chain subtending multiple systems in
support for over 31,000 xDSL ports in a single switching
group. As a result, the Stinger FS+ enables not only
migration from traditional telephony, but the highest
performance, most redundant interconnections (whether
through gigabit or ATM interfaces) for local and long
distance data, voice and video services. This level of built-in
redundancy and reliability means that you can now offer
advanced IP services, including VPN and interactive multimedia
services, with complete confidence.
