Краткое описание:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The GTD-5 EAX is the Class 5 telephone switch developed by GTE Automatic Electric Laboratories. This digital central office telephone circuit switching system is used in the former GTE service areas and by many smaller telecommunications service providers. The GTD-5 EAX first appeared in Banning, California on June 26, 1982, slowly replacing the electromechanical systems still in use in the independent switch market at that time. The GTD-5 EAX was also used as a Class 4 telephone switch or as a mixed Class 4/5 in markets too small for a GTD-3 EAX or 4ESS switch.
