Abstract

1,043,072. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Jan. 8, 1965 [Jan. 9, 1964], No. 961/65. Heading H4K. In a system employing register-senders, checking signals are sent back to the calling subscriber concurrently with the emission of routing signals. Either DC or VF impulsing may be used, and in the latter case a separate generator may be provided for the checking signals.
