Multiservice capabilities for increased
revenue generation
With the multiservice capabilities of the Alcatel-Lucent
1540 Litespan Family, you will be able to expand your
revenue-generating opportunities. In addition to providing
basic narrowband voice and data services (using POTS,
ISDN, basic access/primary rate access, digital leased
lines), the system delivers broadband Internet access,
data transmission and video applications (such as VoD
or IPTV) capabilities over digital subscriber lines (ADSL,
ADSL2 or ADSL2plus) and global standard high bit rate
DSL (G.SHDSL) to enable quicker business data services
for business end users. Alcatel-Lucent’s 1540 Litespan
represents the perfect triple-play solution for many types
of access network scenarios.
Support of multiple topologies for more
flexible applications
Star, ring, tree, point-to-point and mixed topologies are
all supported.
Support of multiple transport options for
easy integration with existing networks
The Alcatel-Lucent 1540 Litespan integrates plesiochronous digital hierarchy (PDH) or SDH transport mechanisms for switching and data networks. An SDH add-drop
multiplexer (ADM) with integrated Ethernet over SDH,
occupies just one board. Asynchronous transfer mode
(ATM) and GigaEthernet transport capabilities are also
in the system. Moreover, traffic can be transported between Litespan exchange units (EUs) and remote sub-
tendingunits(RUs)throughcopperlines(usingHDSL
or g.SHDSL transport protocols), fiber connections or
external leased-line networks.
Broadband (xDSL) traffic is routed through synchronous
transport module 1 (STM-1) optical or E3/DS3 electrical
interfaces to the ATM backbone, and through a GigaEthernet port (10/100/1000Base-T or optical 100/1000 FX)
to the (typically) IP backbone. This increases your flexibility when connecting to the IP data backbone through
Metro Ethernet networks.

investment protection
The Alcatel-Lucent 1540 Litespan
family is designed with standard interfaces (V5 for TDM voice services,
SIP Megaco/H.248 for VoIP, and
ATM or Ethernet for xDSL traffic)
to ensure that it functions effectively
in open environments. This open
design lets you build competitive,
customized solutions compatible
with your existing investments and
customers’ needs.
Rapid deployment for faster
revenue generation
With the Alcatel-Lucent 1540
Litespan family, your deployment is
simplified because the indoor racks
and outdoor cabinet configurations
are delivered from the factory completely built and tested. You can
also provision the system from a
centralized management center or
a local craft terminal. Moreover,
the management system is consistent
with established systems, minimizing
the learning curve. In short, all of
these features significantly shorten
your time-to-revenue.
Lower CAPEX and OPEX and
increased revenues
Because the Alcatel-Lucent 1540
Litespan family provides so many
services on a single platform, it can
significantly affect your overall revenues. Plus, its flexible design ensures
you can easily add new services as
user demand requires them.
Just as important, the Alcatel-Lucent

Future-ready and safe investment evolution to NGN
The Alcatel-Lucent 1540 Litespan
is designed to be NGN ready, letting
you smoothly convert from a multiservice access platform supporting
today’s TDM services to a full access
media gateway in NGNs. Through
the simple insertion of a VoIP gate
way card, you can transform the
node into an NGN access gateway
that supports VoIP services with
minimal future investment. You can
also choose which customers remain
connected to the legacy TDM backbone and which migrate to the new
NGN backbone.
