Title:
COMMUNICATION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2749279
Kind Code:
B2
Abstract:
PURPOSE: To realize real-time communication owing to a virtual line and to automatically establish the virtual line at the time of turning on a power source even when the virtual line is disconnected.
CONSTITUTION: First of all, master equipment designates the addresses of communication control equipment 168-16n and transmits a session establishing command to multisession type communication control equipment 11. Thus, the multisession type communication control equipment 11 performs communication with the address designated communication control equipment 16a-16n through high frequency MODEM 13 and 15a-15n and high frequency transmission line 14, establishes the virtual line, registers the addresses of the opposite side communication control equipment 16a-16n and the port numbers of communication ports 17a-17n on a virtual line managing table and stores virtual line information in a non-volatile memory. When the virtual line is disconnected, the virtual line is automatically established based on the virtual line information stored in the non-volatile memory at the time of turning on the power source of the multisession type communication control equipment 11.
