The Alcatel-Lucent 4ESS Switch addresses long-distance call completion time. The 4ESS effortlessly handles 500,000 calls per hour which is 10 times the capacity of the electro-mechanical switch it replaced. It contributes to a noticeable boost in service speed. The switch, shared with related technology of common channel signaling, markedly improved long-distance completion time from 10-20 seconds to only 1-2 seconds. The 4ESS delivers the cleverness, adjustability, and quickness for improving the long-distance network.
