A few questions. I'm completing my paper on the effect of fiber cuts on the Internet, and I'm looking for a few data sources or SWAGs. How much Internet dialup is done via access banks connected to CLEC lines versus to Bell/ILEC lines? What percentage of the CLEC Internet dialup ports depend on a third-party (i.e. Illuminet) SS7 data channel to complete the call between the typical residential/business user on an ILEC line and the ISP on a CLEC line? My theory is because many of the ISP ports have migrated off the ILEC networks onto CLECs they are impacted by a SS7 failure more than the traditional call traffic. SS7 failures are very rare, but the two I know about disrupted dialup ISP access across huge geographic regions.
