Tellabs Enhances 3G Wireless Transport

Tellabs has expanded the wireless transport capabilities of the Tellabs 5500 digital cross-connect with optimization of wireless backhaul, integration of voice-quality enhancement and DS-0 grooming.

This evolution of the Tellabs 5500 system creates more backhaul flexibility and capacity for service providers while shrinking the total footprint and simplifying their radio access networks, said Dan Kelly, executive vice president of transport products for Tellabs. “These new capabilities deliver an integrated, carrier-class wireless backhaul solution.”

The Tellabs 5500 system improvements for wireless service providers include:

* 40 percent to 50 percent savings in backhaul transmission bandwidth through elimination of idle transmissions and packetization of cell site traffic. As part of the Tellabs IntegratedMobile solution, the Tellabs 5500 system enables seamless migration from TDM and ATM to an all-IP-based backhaul, the company said.

* The addition of integrated voice-quality enhancement (iVQE) and DS-0 grooming (iDS-0) into the Tellabs 5500 system, eliminating the need for separate VQE and 1/0 grooming equipment. The Tellabs iVQE and iDS-0 solutions decrease power consumption, cabling and maintenance resources compared with standalone VQE and DS-0 grooming solutions.

* A 50 percent increase in switch core capacity while significantly reducing floor space, critical for mobile switching offices with limited space.

The iVQE and iDS-0 features are available now; optimization of wireless backhaul will be available in the third quarter of 2006.
