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.
