It's a co-operative, territory-wide Australian federal government (dark fibre) network called ICON. See: http://www.finance.gov.au/icon/ It was just easier to call it a 'dark fibre' service, since that terminology will be familiar to most of you. It is neither cheaper or more expensive, it's just the way it is. It _is_ 'dark', but in parts of the network, particularly in and around the city centre, there is a lot of contention for fibres. A few years ago, ICON started delivering "circulators" at each end and using a single strand between endpoints to conserve fibres. If a customer wants both 1310nm and 1550nm wavelengths available, a WDM will be installed as well. In practice, of course, I could plug whatever I wanted into it, within the single-strand limitation -- I don't have to use the "circulator" provided. So, now that you all have the background, any tips re: my original query? :-) cheers, Dale _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
