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.
