directly onto a SONET network (see
Figure 3). VCAT enables these operators
to offer low-cost Ethernet services, while
maintaining all the benefits of SONET
networking and without requiring drastic
changes to the network infrastructure
or operational systems.
GOING FROM STRENGTH TO STRENGTH
Alcatel-Lucent continues to invest heavily
in the development of the 1677 SL, winning
industry interest and customer satisfaction.
Recently added functionality includes
Gigabit Ethernet broadcast, dual-ring
interconnection, transmultiplexing without
the need for a vertical switch controller
(VSC), DS1 management integration, and
DS0 grooming. More is on the way for this
exceptionally flexible and upgradeable
solution.
