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.
Malicious spammers' aim to spread viruses through electronic communication channels. We have identified three sub-categories related to the nature of the spammer. Also, as wireless devices become more complicated and multifunctional (combined phone...
The Ethernet uplink from the DSLAM can be run on a spare fibre or, using a separate wave division multiplexing box, on one already in use by the ATM network. Instead of adding more expensive ATM channels for new subscribers, they can be put onto...
Understanding the detail is not easy and is probably easiest to conceive of as thousands of micro-radio channels broadcast in parallel all at the same time. Such 'spread spectrum' systems were originally developed towards the end of WWII for secret...
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.
In the not too distant future, you will be able to add 3G Long Term Evolution (LTE), mobile WiMax, multiple in multiple out (MiMo) and orthogonal frequency division multiplexing (OFDM) to the mix. Software that makes mobile broadband easy to use...
