摘要

A personal telecommunication connection number having e.g. three digits is allocated (1) for input via the personal computer (2) into a programmable selection system (5) while the toll is calculated. The computer (2) allows a call of limited duration while requesting the input of the undisclosed number. A numbering system (3) detects a connection remaining free, and this is opened (4) by the input of the time limit. The exchange (6) makes external connections (7) to the public network. USE/ADVANTAGE - In a system with e.g. 1000 connections. The telephone can be used without disclosure of identity through the directory number.
