The network relies on Nortel's Dense Wave Division Multiplexing to offer speeds of up to 10Gbps. We have always sold our spare capacity, but growing demand now makes it worthwhile to set up a parallel business as a carrier's carrier.
Nortel is taking the dense wavelength division multiplexing approach - which combines different coloured streams of laser light onto one strand of fibre. Nortel Networks Carrier Packet Solutions has said this week that it has come up with a...
All that is set to change with the advent of carrier-class Ethernet services and transport. A new telco-friendly version is emerging that will support third-party services, and offer high reliability at a fraction of the cost of existing networks.
However IP traffic is transported - either over SDH or an IP overlay network - the aim is to provide a multiservice network capable of great things. But it may well provide the basis for the mythical multiservice network, where enterprises will be...
Carriers using the technology can reduce operating expenses by sharing bandwidth resources across the network. The carrier will be using Cisco 12000, 7300 and 7200 series routers and its Catalyst 4500 series switches.
While it is true to say the vast majority of call centres still use traditional switching (aka Time Division Multiplexing or TDM) and plan to do so for the foreseeable future, IP is progressing towards a point of dominance.
