I'm still unimpressed. As most who participate in this forum know, a prerequisite to CLASS is SS#7 between participating offices. Without that, the data required for the handshake necessary for CLASS services cannot be sent. For well over a year now, all Bay Area COs have been speaking SS#7 between switches that are capable of it. Presumably, they want to be ready when the PUC stops picking its teeth. Actually, what I meant to say was, "All Bay Area COs except the three in Los Gatos and the one in Morgan Hill." This is, of course, our token GTE punishment area. (Doesn't everyone have to suffer with GTE somewhere nearby?) These COs (all GTD-5) speak MF to each other and to the outside world. No CLASS available here! What this means to a telephone user, CLASS aside, is that a call from a point in Los Gatos to a telephone a few blocks away takes NOTICABLY longer to complete than a call from San Jose to San Francisco, a distance of about 45 miles. Once again--the wonders of GTD-5. I have received many kilobytes of material from GTE folks trying to sell the virtues of GTD-5. But after my little experimentation, I'm going to invoke my Jackson County, MO heritage: Show me! John Higdon | P. O. Box 7648 | +1 408 723 1395 john@zygot.ati.com | San Jose, CA 95150 | M o o !
