7Alcatel-Lucent 1671 Service Connect
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.
