Tellabs enhances transport switch

Tellabs Inc. this week unveiled enhancements to its 6500 transport switch designed to reduce capital and operational costs.

The enhancements include support for two-fiber or four-fiber bidirectional line switched ring topology that reduces the need for additional add/drop multiplexers; and an asymmetrical ring configuration that reduces the need for additional transponders.

Other enhancements are a new ring manager feature for the Tellabs 6592 integrated system manager that enables service providers to manage end-to-end circuits all at once instead of individually. Another is a remote shelf capability that enables 6500 port shelves to be located in any central office within 25 miles from the switch core, eliminating the need for multiplexers at the hub and end-office locations.

The Tellabs 6500 is a broadband transport platform that performs bandwidth grooming, add/drop multiplexing and cross-connections. The enhancements are included in feature package 2.1, which will be available in the fourth quarter.
