ABSTRACT:
A communication terminal apparatus connected to a communication network through a data channel for transfer of line transaction data or packet transaction data and through a signal channel for control of a call to a communication destination party.

These subscriber numbers and subaddresses are transmitted and received through the signal channel separately from transaction data transmitted and received through the data channel. The present apparatus performs predetermined control operations, depending on whether or not the then received subscriber number (subaddress, if necessary) coincides with one of the previously registered subscriber numbers (subaddresses); the operations include:
