DIGITAL CORDLESS TELEPHONE SET
Document Type and Number:
Japanese Patent JP3172350
Kind Code:
B2
Abstract:
PURPOSE: To reduce the load of a control data processing part by prolonging time for processing control data when performing inter-slave set speaking via a master set and to prevent noise from being reproduced as voice data on the side of a slave set when similarly performing inter-slave set speaking via the master set.
CONSTITUTION: A control data processing means 28 communicates plural digital cordless telephone sets. Buffer selecting means 1 and 2 store the transmitted/ received data in the proper positions of the transmitted/received data buffers installed for each slot in a TDMA/TDD system. An error detecting means 6 detects the error of the received data and turns transmitting data to '0' at the time of error detection. Two systems of transmitted data buffers 3 and 4 are provided, these two transmitted data buffers are switched by SW1-SW4, and the processing time of the control data processing means 7 at the time of inter-slave set speaking via the master set is defined as four slots or above.
