The Lucent 5ESS switch design is proven every day on approximately 6,000 host switches in more than 66 countries. According to recent U.S. FCC quality reports, the 5ESS switch is the only switch that has achieved nearly 100 percent availability for six consecutive years.

The unique architecture of the 5ESS switch enables modular upgrades and implementation of multiple services on one switch, providing strong economies of scale in training, management, and spares. As a result, you can pursue business and network strategies without locking your company into a specific technology and without interrupting current services.
