Alcatel-Lucent 1353 Litespan Management System (LMS)8
Support of multiple topologies
Star, ring, tree, point-to-point and
mixed topologies are all supported
by the Alcatel-Lucent Litespan
family. All topologies can be super-
vised from the Alcatel-Lucent 1353
LMS Map Manager. In all of these
topologies, network management
information can reach the access
nodes from the Alcatel-Lucent 1353
LMS through either in-band or
out-band mechanisms.
Support of multiple
transport options
The Alcatel-Lucent 1540 Litespan
and Alcatel-Lucent 1353 LMS inte-
grate plesiochronous digital hierarchy
(PDH) or SDH and Ethernet over
SDH transport mechanisms toward
the switching and data networks.
PDH, asynchronous transfer mode
(ATM) and Ethernet transport
capabilities are also in the system.
Transport is supported between
Alcatel-Lucent Litespan exchange
units (EUs) and remote units (RUs)
using HDSL or G.SHDSL transport
protocols, fiber connections or exter-
nal leased-line networks.
Equally important, broadband
(xDSL) and narrowband (voice and
leased-line data) traffic can share the
same fiber (SDH STM-1 or STM-4).
Broadband (xDSL) traffic can be
routed through STM-1 optical or E3/
DS3 electrical interfaces toward the
ATM backbone. For its part, xDSL
traffic can be redirected toward
the backbone (typically IP) over
Ethernet (1000Base-SX, 1000Base-
LX, 1000Base-EX, 1000Base-ZX
and 1000Base-TX). This increases
flexibility when connecting to the
IP data backbone through metro
Ethernet networks. You can manage
all of these transport options with
the Alcatel-Lucent 1353 LMS.
