Tellabs Targets Ethernet-Over-Sonet

NAPERVILLE, Ill. -- Tellabs (Nasdaq: TLAB - News) today introduced a suite of next-generation SDH (synchronous digital hierarchy) transport solutions featuring new high-speed data interfaces for its Tellabs 6300 managed transport systems that enable service providers to maximize their network capacity and generate new revenues. The Tellabs 6300 series will grow with service providers' needs, support the Ethernet capabilities they need to better utilize their SDH networks today, and provide additional switching and bandwidth allocation features as needed in the future. To support carriers' migration to high-speed data services, Tellabs is introducing its SDH-based data solutions in three phases.In the first phase, Tellabs will add Gigabit Ethernet capabilities to the Tellabs® 6340 switch node and Fast Ethernet capabilities to the Tellabs® 6310 edge node, the Tellabs® 6320 edge node and the Tellabs 6340 switch node. With these built-in Ethernet interfaces, service providers can efficiently map Ethernet traffic into VC-12 or VC-4 containers in the SDH network using virtual concatenation. This enables carriers to offer virtual private leased lines scaling from 2 Mbps (Megabits per second) to 1 Gbps (Gigabit per second).Beginning in late 2002 as part of the second phase of the solution, Tellabs will add state-of-the-art Layer 2 switching and quality of service capabilities to the Tellabs 6300 series that will support advanced Ethernet virtual local area network (VLAN). The solution will enable carriers to support unlimited numbers of VLANs on the transport network and efficiently groom and control Ethernet traffic without investing in external Ethernet switches. Carriers also can cost-efficiently provision and control VLAN and virtual private network services to reduce network complexity and increase flexibility and cost savings.The third phase will incorporate the functionality of GMPLS to engage the SDH transport network resources in the intelligent traffic engineering. This will enable carriers to dynamically allocate and control of bandwidth, provide bandwidth-on-demand for just-in-time service creation and enable sharing of network capacity reserved for protection. Introduction of GMPLS-based automated provisioning is expected to enable carriers to save up to 80% in operating time and costs.Tellabs Inc.
