<p>PURPOSE:To eliminate the need for an exclusive remote access installation by allowing remote access only when a destination address and an address of a registered communication equipment are coincident so as to inhibit illegal remote access and implementing access through the utilization of a service offer use communication control section. CONSTITUTION:A PAD control section 42 discriminates the presence or absence of an identifier from an incoming call and its address is collated with its own equipment address by a storage section 46 in which addresses are registered. When the addresses are coincident, addresses in a remote access enable user address table 48 and a caller address are collated and remote access is accepted only when they are coincident, and communication is interrupted when dissident. On the other hand, an identifier of the PAD is judged to be absent, the address is converted according to an address table 47 to implement usual communication. Thus, the installation for exclusive remote access is not required and illegal remote access is inhibited.</p> |
