Japanese Patent JP3133723
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the processing time required for band assignment and to simplify the circuit for the transmitter to reduce the cost. SOLUTION: A demand terminal at a transmitter side stores a demand signal 104 produced on the occurrence of a line connection request to a register 13. The signal is read at a prescribed period by an assignment synchronizing signal 112 and given to a transmission assignment control section 14. The transmission assignment control section 14 generates and outputs a transmission timing signal 103 to an FR terminal corresponding to a transmission selection control signal 110 for referencing band assignment information denoting a current band assignment state held in itself and to designate an assigned position of a line which received a demand. A transmission selector 11 assigns in batch transmission data signals 102, 103 of a channel receiving the demand. A reception selector 17 of a receiver side extracts the data signal assigned at the transmitter side, synchronously with the transmitter side and outputs a reception timing signal 201 at the same time.
