6 Alcatel-Lucent 1671 Service Connect
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.
