Title:
FALSE CALL CONNECTING DEVICE
Document Type and Number:
Japanese Patent JP3444714
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To simulate many terminals with small-scale constitution without causing congestion as to the false call connection device which is connected between a frame relay relay exchange that communicates data at a high speed through multiple interfaces having a specific transmission rate and false call generating device that generates a false call frame, and then tests the frame relay exchange.
SOLUTION: Frame-multiplexed false call frames from the false call generating device 2 are multiplexed on a time-division basis by a frame processing part 6 or 7 to obtain a signal having a specific transmission rate. This signal is demultiplexed on a time-division basis by a demultiplexing part 5 according to a correspondence pattern between the externally instructed frame processing part 6 or 7 and a channel group on the multiple interfaces and sent out as another signal having the specific transmission rate to the frame relay exchange, which sends the false call frame back to the false call generating device 2 by the reverse processing through the reverse course.
