Provide high call quality while reducing costs.
Use 39% less power and save space with integrated system.
The Tellabs® 5500 Integrated Voice Quality Enhancement (iVQE) integrates world-class voice quality improvements and network performance enhancements right into Tellabs® 5500 Digital Cross-Connect Systems (DCS).
Any facility termination on the Tellabs 5500 system can be cross-connected to the iVQE shelf. You can access an echo control solution to make your digital wireless and long-distance calls sound even better.
Economical, easy to install, easy to use
The Tellabs® 5500 iVQE solution reduces your footprint and eliminates tandem ties. It also decreases installation time and simplifies management. The Tellabs® 5500 iVQE system enables fast and stable convergence across a wide range of hybrid echo paths. It system includes all of the capabilities of the Tellabs 3600® VQE system.
Your phone calls will be high-quality from start to finish, including during call transfers, cell hand-offs and after abrupt changes in network routing.
Customer Benefits
- Improve your customers' experience with high-quality calls to increase subscriber revenue, reduce churn and improve customer retention.
- Reduce your footprint by eliminating the stand-alone VQE system.
- Reduce your operating costs. The Tellabs® 5500 iVQE system uses 39% less power than comparable systems and eliminates facility interconnections.
- Improve reliability. The Tellabs® 5500 iVQE system provides five-nines (99.999%) availability.
- Save time and resources. Manage provisioning and alarms remotely using Tellabs MetroWatch Integrated Network Manager (INM). The manager enables both circuit and echo cancellation provisioning and eliminates the need for engineers to travel to configure echo cancellers.
Product Features
- Supports T-1 through OC-48 terminations.
- Level control dynamically adjusts speech levels up or down.
- Noise reduction makes speech clearer and more intelligible by quickly and dynamically reducing background noise on mobile calls.
- Eliminates acoustic echo generated from digital mobile handsets and hands-free kits and hybrid echo generated from the PSTN network.
- Adaptive gain makes calls in high background noise environments clearer by automatically adjusting speech levels and spectral content.
- A performance probe monitors the effectiveness and operation of the voice quality enhancement features.
- One high-density port shelf on the Tellabs® 5500 DCS equipped with four working iVQE mapping modules supports up to 16,128 DS0s, or 24 DS-3 of echo cancellation.
- Each Tellabs® 5500 system iVQE shelf has twice the density of a Tellabs® 3600 VQE shelf while offering up to 192 ms Hybrid Echo Control.
