摘要

PROBLEM TO BE SOLVED: To send data without impairing synchronization between frame and bit of data in an inter-station connection channel used for various radio systems. ;SOLUTION: This device is constituted of synchronization MODEMs 3, 4 that are connected between analog or digital lines and send/receive voice or non-voice data, a control station 1 that is connected to the synchronization MODEM 3 to send data, and a base station 2 that is connected to the other MODEM 4 consisting of at least two channels, receives data, adopts at least one of frame synchronization, bit synchronization, slave synchronization and system clock synchronization to obtain a data conversion timing for voice coding decoding components. Thus, the inter-station synchronization device for the radio system is obtained, where the frame synchronization, bit synchronization, slave synchronization or system clock synchronization can be warranted.;COPYRIGHT: (C)1999,JPO
