Hi
I would like to know which switch is good for 500 port digital land lines. it should be upgradeable to 5000 lines with crds.
secondly how to carry 1000 ports from copper to 3km away by means of fibre optical cable of analog land line telephones to save on cost of copper.
i shall be grateful if any one can tell me
