The WaveStar™ BandWidth Manager:: The key building block in the next-generation transport network

The WaveStar(TM) BandWidth Manager (BWM) is Lucent Technologies' flagship product platform for providing bandwidth management within network nodes. It provides broadband (OC-3/12/48/192 and STM-1/4/16/64), asynchronous transfer mode (ATM), and Internet protocol (IP) bandwidth management within a highly-integrated, scalable, single network element The WaveStar BWM's broadband synchronous transfer mode (STM) fabric scales from 1152 STS-1/384 STM-1 (60 Gbls) to 9216 STS-1/3072 STM-1 (480 Gbls) port capacity. With such a high range in capacity scalability across the broadband STM fabric, the BWM can be sized to meet most carriers' growth projections while protecting them from unforeseen growth within network nodes. The WaveStar BWM also addresses the growing need for enhanced bandwidth management capabilities within central offices. It integrates all access and transport facilities within a network node and efficiently manages bandwidth among these facilities via a cost-effective, scalable, multiservice switching architecture. The BWM facility interfaces, which feature integrated self-healing rings, eliminate the need for stand-alone add/drop multiplexer (ADM) ring terminals in the central office. Furthermore, the switching architecture, which includes an STM fabric as well as ATM and IP functionality replaces the need for stand-alone broadband digital cross-connect systems (BDCSs) and ATM and IP core switches/routers. The WaveStar BWM also supports direct integration of Lucent's dense wavelength division multiplexing (DWDM) systems-the WaveStar optical line system (OLS) 400G and the WaveStar OLS 40G.
