CONSTITUTION:In registrating an abbreviated dial of a subscriber A, a marker 5 connects the call to an outgoing register 2 via a switch frame 1. The subscriber A recognizes the connection to the register 2 and dials the number of registration. When the reception is finished, the register 2 selects an abbreviated dial information storage means 3 and stores the abbreviated number. The device 3 is provided with a secret number registrating means for each subscriber. In using the registration number from the subscriber A, an incoming subscriber B connects with the marker 5 via the switch frame 1 and an intra-office trunk 4. The register 2 is provided with a secret number collating function to use the abbreviated number of itself from the other telephone sets. |
