摘要： The present invention discloses a parity detection device and method in a CDMA mobile communications system, which detects parity error in data output from a cell site modem (Q51601-2S1), and controls the data output when the parity error occurs, to improve the reliability in data communication. The invention converts serial data to be transmitted through a CSM into parallel data, checks if there is a parity error in the parallel data, and generates an interrupt when a parity error is detected. When the interrupt is generated, an output controller restrains the transmission of the serial data to be transmitted, which is outputted from the CSM, thereby preventing data having error from being transmitted.

摘要： A circuit for converting frame data is disclosed, in which data communications can be carried out by matching the T1 repeater line of the North American method and the E1 repeater line of the CEPT. The four 32-channel frame data of the E1 line of the CEPT method are converted into parallel data of 8-bit one channel, and are stored into four 64-byte buffers. The stored 32-channel frame data are read out by 24 channels at a time, while the remaining data of the 6 channels are added to the data which have been stored in the buffers. Thus five 24-channel frame data are converted into serial data before being outputted. Of the five 24-channel frame data of the T1 repeater line of the North American method, four 24-channel frame data are stored into four 64-byte buffers, while the remaining one 24-channel frame data are separated by 6 so as to store them into the four 64-byte buffers, so that the four 64-byte buffers can store the 32-channel data respectively. The 32-channel data which have been stored in the four 64-byte buffers are sequentially read out, and then, are converted into serial data before outputting them.
