Abstract

Disclosed is a Private Branch eXchange (PBX) improved method using an Integrated Circuit (IC) card system with the idea that the IC card owner can freely use any one of many interphones without any registrations by separating the phone number from the phone. An IC card reader is mounted in a phone terminal, including interphone and mobile Personal Computer (PC), etc.. The IC card has a registered phone number and the terminal operates as a phone when the card is installed. This is useful for the IC card owner because the terminal can be used anywhere as his own phone.

Private Branch Exchange with Integrated Card Reader

      Disclosed is a Private Branch eXchange (PBX) improved method
using an Integrated Circuit (IC) card system with the idea that the
IC card owner can freely use any one of many interphones without any
registrations by separating the phone number from the phone.  An IC
card reader is mounted in a phone terminal, including interphone and
mobile Personal Computer (PC), etc..  The IC card has a registered
phone number and the terminal operates as a phone when the card is
installed.  This is useful for the IC card owner because the terminal
can be used anywhere as his own phone.

      As the traditional phone has only one number, the registration
or changing work of the number on the Telephone Exchanger is
mandatory in the event the user wants to utilize the other phone as
his own.

      Fig. 1 shows an application sample for a wire-carried phone,
and Fig. 2 is for a wireless one.  The phone system has an IC card
reader, and a phone number and an Identification Code (ID) are
registered in the IC card.  To use the terminal as a phone, the user
inserts his IC card in the IC card reader and inputs his ID code from
the keyboard.  When his code is certified in the phone and the
Telephone Exchanger accepts the connection request from the phone, it
becomes possible to use it as a phone with his phone number.
Therefore, the certification can prevent a theft.
