Network planners believe that maximizing revenue and
minimizing cost is best achieved through the consolidation
of network elements, which in turn leads to increased
overall network efficiency. The Alcatel-Lucent 1671 SC
provides a path for central office and network optimiza-
tion by offering the features and densities needed to achieve
these goals. The MSM is available on all new Alcatel-
Lucent 1671 SC systems or can be added, in service, to
all existing Alcatel-Lucent 1671 SC systems via a simple
plug-in unit replacement, as illustrated in Figure 3.
The 80G center stage can be
easily swapped out for the new
240G center stage, while the
new 20G end stage cards, shown
in blue, replace the functionality
of the previously discrete 5G link
end stage cards and switching
cards, shown in yellow and
green respectively. This allows
the Alcatel-Lucent 1671 SC to
offer 4,608 STS-1 equivalents in
only two seven-foot racks, with
Copy 0/Copy 1 redundancy, far
outclassing the density of
competitors’ devices.

Flexible Matrix
In addition to a full range of inter-
faces, the Alcatel-Lucent 1671 SC
promotes network versatility by
supporting a variety of network
topologies. As a multiservice cross-
connect, the Alcatel-Lucent 1671 SC
offers a valuable solution for multi-
protocol networks. As versatile as
it is efficient, the Alcatel-Lucent
1671 SC provides VT1.5, DS0 and
STS-n grooming, enabling carriers
to maximize the productivity of
their infrastructure.
Figure 4 illustrates how various pro-
tocols at differing bandwidths are
switched by the non-blocking and
versatile MSM. For example, the
green line, which enters the I/O card
as a DS3 wideband signal, is provi-
sioned as a VT1.5 channel to pass
through the MSM. After switching
and multiplexing, it is represented as
a DS3 at the output. Correspondingly,
the blue line enters an I/O card as an
OC-12c signal which is then software
provisioned as a broadband STS-12c
clear channel. After switching, it is
presented at another output as an
OC-12c. For narrowband switching,
the red line illustrates the entry of
an OC-n signal that is software
provisioned as VT 1.5 with DS0
grooming. The MSM hands off the
VT signals to a dedicated DS0 switch
matrix that completes the switching
and then hands the signals back to
the MSM. In this example, the
narrowband signals are multiplexed
to a DS1 output. All of these connec-
tions are internal and implemented
via software commands.

Enhanced Data Shelf
The multiservice capabilities of the Alcatel-Lucent 1671 SC make it possible
to extend the data network closer to the customer and to support adaptation
to a unified multiprotocol label switching (MPLS) core. This allows the service
provider to make more efficient use of expensive router ports provisioned for
the delivery of data services, which leads to increased cost efficiencies. In fact,
with a reduced delivery cost, it may be possible to extend services to areas
where, in the past, it was not economically feasible to do so.
The Enhanced Data Shelf (EDS), illustrated in Figure 5, supports data
applications such as data aggregation, Layer 2 switching and circuit emulation.
By providing full SONET and data interworking, the Alcatel-Lucent 1671 SC
can support legacy functionality now, and incrementally switch capacity over
to data functionality as new services come on line; or it can be immediately
commissioned as a data transport solution. The EDS accepts signals that
include, but are not limited to, Gigabit Ethernet, clear channel and concate-
nated payloads, DS1, DS3, and OC-3 to OC-192 SONET; and this includes
any-to-any connectivity.
