Facts on Multiservice Access Router Performance - ADTRAN Outperforms Nortel in Tolly Group Tests

It is critical that a router deliver high throughput in converged network environments, and equally important to maintain superior voice toll quality. This independent test by Tolly Group provides a competitive performance evaluation of how ADTRAN outperformed Nortel.

Test scenarios in the report include:

• Double the performance of zero-loss throughput over an Ethernet-to-Ethernet link with firewall and VPN services active
• Achieves exceptional voice quality well beyond PESQ-LQ toll-quality thresholds when subjected to severe congestion
• Layer 3 zero-loss throughput across a back-to-back WAN connection
