Tellabs introduced its NGX family of next-generation transport switches designed to integrate bandwidth management and transport functions while scaling up to 5,376 STS-1 equivalent capacity (2,688 STS-1s for fully-protected TDM applications). The new Tellabs 5500 NGX-MX transport switch reduces central office floor space requirements by 90% compared to first-generation digital cross-connects and stacked add/drop multiplexers (ADMs). Integrating digital cross-connect and transport systems into one switch also reduces inter-machine tie-trunks that would otherwise be needed between separate network elements. The new switch is part of the re-branded Tellabs NGX transport switching portfolio. This line-up includes:
- the Tellabs 5500 NGX transport switch (formerly the Tellabs 5500 NGX next-generation cross-connect), which provides OC-48 transport, dense optical connectivity, efficient ring and broadband traffic support and data capabilities;
the Tellabs 5500 NGX-S transport switch (formerly the Tellabs 6400 transport switch) -- a compact, single-shelf multi-bandwidth management solution that features STS/VT and M13 bandwidth management flexibility and converges it with SONET and data transport;
the new Tellabs 5500 NGX-MX transport switch -- a scalable, multi-bandwidth management solution that builds on the Tellabs NGX-S transport switch to add non-blocking growth for up to 5,376 STS-1 equivalents (2,688 STS-1 capacity for fully-protected TDM applications). The Tellabs 5500 NGX-MX transport switch will be available in Q3.;
the Tellabs 7120 NGX advanced transport node -- a compact OC-48/192 SONET transport system for distributed transport nodes with advanced bandwidth grooming and multi-service transport capabilities.
