Alcatel-Lucent1671 Service Connect 5

Flexible Matrix

In addition to a full range of interfaces, the Alcatel-Lucent1671 SC promotes network versatility by supporting a variety of network topologies. As a multiservice crossconnect, theAlcatel-Lucent1671 SC offers a valuable solution for multiprotocol networks. As versatile as

it is efficient, the Alcatel-Lucent1671 SC provides VT1.5, DS0 andSTS-ngrooming, enabling carriers to maximize the productivity of their infrastructure.

Figure 4 illustrates how various protocols at differing bandwidths are switched by the non-blockingand versatile MSM. For example, the green line, which enters the I/O card as a DS3 wideband signal, is provisioned 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-12csignal which is then software provisioned as a broadbandSTS-12cclear channel. After switching, it is presented at another output as anOC-12c.For narrowband switching, the red line illustrates the entry of anOC-nsignal 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 connections are internal and implemented via software commands.

Enhanced Data Shelf

The multiservice capabilities of the Alcatel-Lucent1671 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-Lucent1671 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 concatenated payloads, DS1, DS3, andOC-3toOC-192SONET; and this includesany-to-anyconnectivity.
