Most of GTE Santa Monica is new EAX/ESS switching, and there is a major GTE long-haul toll switching center right there in Santa Monica as well. This makes the probability very high that the tests used nice, clear, digital trunks over most of the route. For real testing, you need to call (and be called from) areas that are more rural (where many Usenet sites are located, by the way) and farther from their local telco central offices and toll centers. Overall and specific path variability is usually much higher when one or both ends of the call are in "odd" locations. For example, I frequently call from my "well-located" (close to central office) Los Angeles location to Douglasville, Georgia (17 miles outside Atlanta). Only about 50% of the calls are usable for ordinary 1200bps 212-type data. --Lauren--
