Document Type and Number:
Japanese Patent JP3296534
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a line switchable multiplex communication equipment especially capable of saving a line using charge in a public line network by line changeover.
SOLUTION: The multiplex communication equipment 1 with line changeover control for selectively connecting an active line 5 provided with a large transmission capacity and a standby line 6 provided with a limited transmission capacity is provided with a data terminal I/F(interface) 18 connected to a data terminal 2, a voice terminal I/F 17 connected to a voice terminal 3, an active line I/F 13 connected to the line 5, a standby line I/F 14 connected to the line 6, a multiplex control part 16 for multiplexing data and voice information, a line changeover part 15 for switching the lines, a control part 11 for generally controlling them and a memory 12 for storing multiplex information in the active line and the standby line and line changeover information. Then, in the standby line 6, only the irreducibly minimum information is multiplexed, a using line speed is suppressed low and the line using charge is saved.
