Telephone switchboards to be managed electronically

Conventional telephone exchanges are electrochemical and require maintenance by skilled technicians. Tomorrow´s device, conforming to the age of automation, will be fully transistorized and will have no moving parts, gears, or contact points that normally require frequent adjustment and repair. Demonstrated recently was such a device, the Kelex 2000, a 100-line model that is designed for private telephone systems in factories, schools, hospitals, offices, aboard ships, or wherever internal systems are needed. The Kelex 2000 was shown by ITT Kellogg, a division of International Telephone and Telegraph Corp.
