When Waxahacie, Texas, was first cutover to dial with a 5XB and ANI, no translator was provided and all the translation were done in the Dallas toll machine. We were especially told not to mention to Waxahachie customers that they could dial Italy, Texas, a CDO down the road from Waxahachie that homed on Waxahachie, because this would tie up a trunk from Italy to Waxahachie to the Dallas 4A, which would then send the call back through Waxahachie to Italy. Trunks were a substantial cost then, and using two trunks to and from Dallas and back was really considered a waste of limited resources. Waxahachie got 6-digit translation later, well before trunks became so readily available at much lesser cost. Wes Leatherock snipped-for-privacy@aol.com snipped-for-privacy@yahoo.com
