Abstract

627,613. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. Aug. 3, 1946, No. 30510/48. Divided out of 627,577. Drawings to Specification. [Class 40 (iv)] In a system for identifying calling subscriber's lines, the operation of a non-locking key causes the association of identification equipment with the operator's position, release of said key initiating the transmission of the calling subscriber's identity to said equipment and each subsequent re-operation of the key causing the complete identification cycle to be repeated. The invention is described with reference to equipment identical with that described in Specification 627,577, which claims other features. Specifications 614,177 and 624,089 also are referred to.
