The Sagem WA3050 compares to Nokia's latest Communicator in some respects - it's a dual-band GSM phone which promises large screen, high-speed data communication (although it will employ packet-based GPRS rather than the circuit-switched and not...
Some think the year 2000 problem was nothing compared to the switch to IPv6. The reasons are the new mobile technologies: GPRS (General Packet Radio Service) and subsequently UMTS (Universal Mobile Telecommunications System).
The cost to the carrier of installing a Gigabit Ethernet network is 20 per cent of a Sonet/SDH network, according to Keene. Namely, Resilient Packet Ring (RPR), which should solve the first problem and ITU x.86, which addresses the second.
But the joining together of purpose-engineered intranets could edge us slowly towards a world where no one produces a circuit switch machine ever again. The move from circuit- to packet-switched IP networks leaves communications companies in a...
SDH provides the reliability of circuit-switched pathways and resiliency should there be a fault but it is overly complex and not nearly as flexible as a native IP architecture when it comes to supporting Ethernet services, for example.
Migrating to a converged network brings a number of complexities - complexities that often can be better handled by a managed service provider. This perceived cost saving came via a reduction in capital and operating expenditure, as a result of the...
