The WaveStar™ 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 Gb/s) to 9216 STS‐1/3072
STM‐1 (480 Gb/s) 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
