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.
Taking advantage of the Alcatel-
Lucent 1540 Litespan family
Support of multiple transport options for
easy integration with existing networks
The Alcatel-Lucent 1540 Litespan integrates plesiochro-
nous digital hierarchy (PDH) or SDH transport mecha-
nisms 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 be-
tween Litespan exchange units (EUs) and remote sub-
tending units (RUs) through copper lines (using HDSL
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 Giga-
Ethernet port (10/100/1000Base-T or optical 100/1000 FX)
to the (typically) IP backbone. This increases your flex-
ibility when connecting to the IP data backbone through
Metro Ethernet networks.
