] Sprint Corp., which sells local telephone services in 18 ] states, has started converting its local-phone network to ] a technology that increases capacity and allows the ] company to sell new services. Sprint will buy ] packet-switching equipment from Nortel Networks Corp. to ] upgrade the network. Under a $1.1 billion agreement with ] Nortel in 2001, Sprint planned to complete the conversion ] in eight years. Now the transition may take 13 years, ] said Michael Fuller, president of Sprint's local ] division. While traditional phone calls travel over ] dedicated circuits that remain open for the duration of a ] conversation, packet-based technology breaks voice and ] data traffic into digital pieces that are sent separately ] and reassembled upon arrival. I wonder if this is VoIP or something else... Sprint starts packet shift |
