Title:
SYNCHRONIZING LINE CONTROLLER AND COMMUNICATION CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP3206037
Kind Code:
B2
Abstract:
PURPOSE: To relieve the load of the communication controller by using a synchronizing line controller so as to eliminate automatically a training pattern in reception data from a synchronizing MODEM.
CONSTITUTION: Upon the receipt of an end code, a communication controller 12 requests the stop of a reception signal element timing to a reception clock stop circuit 33, the stop circuit 33 commands the stop of a reception signal element timing to a reception clock control circuit 35 and the reception clock control circuit 35 stops the application of a reception signal element timing 103 from a synchronizing MODEM 13 to a communication transmitter-receiver 31. When a reception carrier interrupt detection circuit 34 detects it that a data channel reception carrier detection signal 104 changes from ON to OFF, the circuit 34 commands the release of the stop of the reception signal element timing to the reception clock control circuit 35, which releases the supply stop of the reception signal element timing 103.
