This brings up an interesting question. I have several BPX ATM switches that I am not using for anything, and I had the bright idea that I would start up some AADS-like exchanges around the country if I could get enough interest. I pinged some of the Dallas area ISP's about the possibility of connecting (I still know some of the guys around here that haven't been gobbled up) and while some expressed interest in connecting, it didn't seem like enough of them were interested to warrant the effort. With the expansion of PAIX and Equinix (and others) into some of the other major markets, will metro exchanges become a thing of the past? Are there simply not enough medium-sized ISP's left in middle-tier markets to justify these types of exchanges? And are the bigger ISP's simply not interested in connecting to any of these metro exchanges? An even better question to this community is this: If I built it would you come? What markets would I need to locate these switches in to make it interesting? If I were to offer connection at cost +10-15% (for O+M) would that make it more interesting? By the way -- the ATM switches seem ideal for this to keep costs down (no collocation necessary), even though the marketplace seems to be moving to Ethernet exchanges. Does anyone have issues with ATM (other than the cell-tax) for this application? Thanks! -- William R. Charnock Director Core IP Tecnology Allegiance Telecom, Inc. 469-259-2260 (O) 972-523-2750 (C)
