Dittberner research shows that during 2004 an increasing number of network operators started the evolution of their fixed network towards the next-generation network architecture at both the tandem/transit and local/class five levels.
"The migration of PSTN to packet telephony is inevitable," said Lilian Tau, VP market research at Dittberner Associates. "There is no universal NGN solution architecture and it is up to each carrier to evolve its network at different rates depending on the state of its infrastructure, on the specific market situation, and on regulatory framework conditions."
Dittberner`s Worldwide NGN Research Programme tracks quarterly shipments of over 29 major equipment suppliers.
