Key Stinger FS+ features and benefits
Stinger FS+ sets a new standard for today’s networks. It
gives you all the functionality, versatility, provisioning,
troubleshooting and management capabilities of its
predecessor, the Stinger FS. But it goes even further.
Leveraging Lucent’s Service Intelligent™ Architecture, the
Stinger FS+ provides a complete, innovative solution that
combines advanced ATM and intelligent IP services all
within the chassis, or distributed as needed, to deliver a
number of exclusive capabilities today:
Cost-saving port density—While many companies claim
to offer the world’s highest density DSLAMs, only the
Stinger FS+ can honestly lay claim to that title. The new
platform increases the capacity of the Lucent DSL offer by
50%. By relying on 72-port modules, it supports 1,008
subscribers per chassis, up to 3,024 per rack, in both ANSI
and ETSI installations. This is over 500 more ports than its
nearest competitor, and 50% greater density than available
previously. The increased density also means you’ll have
lower capital and operating expenditures because it:
• Reduces power consumption per port by more than 30%

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.
• 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.

Multi-service capabilities from a single platform.
In addition, the Stinger FS+ chassis and components are
built on the same operating system, enabling inherent
switching awareness by all components of any Stinger
product. So, if you add or replace a card, it is easily
configured and automatically becomes part of the Service
Intelligent Architecture.
Performance from robust routing—Routing
functionality is distributed across every routing card. By
making each its own routing engine and lowering reliance
on costly, or unreliable, centralized routing devices, Stinger
FS+ improves the overall robustness of your networks. In
addition to greater flexibility in how your network is
deployed, you get added backup and redundancy.
Definitive Quality—Not only does the FS+ architecture
have exceptional quality, with no single point of failure
and integrated loop testing, it also features Automatic
Protection Switching (APS)/Multiplex Section Protection
(MSP). This compelling redundancy feature enables the
Stinger FS+ to work with Stinger’s sister architecture, the
AnyMedia
®
Access System, to transport both voice traffic
and DSL data in a fail-safe manner.
Multiple levels of redundancy—With Stinger FS+ you
also benefit from exceptional built-in redundancy for
mission-critical business xDSL, including:
• APS/MSP for 1:1 trunk port redundancy with hot standby
and sub-25 millisecond switchover
• 1:n subscriber port redundancy and independent 1:n
switching of failed ports
• 1:1 trunk port redundancy and network node failure
recovery via PNNI/Soft PVCs
• Multiple trunks to enable protection and to accommodate
diverse facilities
• Hot-swappable subscriber and trunk modules
• Distributed power system with redundant line filters
Support for advanced applications—You will find that
today’s and tomorrow’s most advanced applications work
easily, supported by:
• IP multicast for broadcast audio/video, interactive TV,
video on demand/pay-per-view
• Subtending of multiple systems in support for over 31,000
xDSL ports in a single switching group
• Gigabit Ethernet and OC-12 bandwidth to the backbone

Stinger portfolio meets every need
The Stinger FS+ chassis supports a choice of optional
modules that perform line testing functions:
Path Selector Module (PSM)—The PSM provides the
full functionality of a Line Protection Module (LPM) in
addition to loop test access. When the PSM is used in
conjunction with a redundant LPM, it provides access from
an external copper loop tester to any subscriber line
attached to a Stinger chassis.
Copper Loop Test (CLT) Module—In addition to
supporting access for an external test set, the Stinger
system also offers its own integrated test module. The CLT
module consists of a PSM with an integrated test head on
a daughterboard. The CLT performs a wide variety of
copper loop testing and qualification functions, simplifying
DSL deployment for carriers.
The Stinger FS+ and the entire Stinger family of DSL
access concentrators, CellPipe™ products, and Integrated
Access Devices (IADs) remain today’s products of choice
for Broadband Access solutions. Lucent DSLAMs fit any
size need. You can choose from architectures for central
