Note: BTL stands for Bell Telephone Laboratories. In the "old days" Bell Labs researched and designed equipment, Western Electric built the equipment, and AT&T and its local phone companies operated and maintained the systems. Bell Labs was responsible for the development of such things as radio astrometry, transistors, lasers, and negative feedback amplifiers.
