Please be aware that the current capacity of the telephone system in the United States (and for that matter, most of the developed world) is only capable of supporting between 15 and 20 percent simultaneous telephone conversations. If the FBI wishes to set up a system that is capable of monitoring 1% of the total number of lines, that equates to a ability to tap 5%, not 1% of all calls in progress.
According to an article that was out on the AP newswire (check under <URL:http://http://www1.trib.com/WIRE/CURRENT/>), the "1%" figure applies to actual capacity. In other words, if there's a switch with 50K subscribers but actual capacity for 5K simultaneous calls, the FBI wants to be able to make 50 simultaneous taps. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Nobody's going to listen to you if you just | Mike McNally (m5@tivoli.com) | | stand there and flap your arms like a fish. | Tivoli Systems, Austin TX | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
