摘要： A terminal adapter for a telecommunication network having a receiver for multiple HDLC communication channels. The receiver includes a BCC calculator for computing and checking the validity of a received HDLC CNM frame. The terminal adapter further includes a device for detecting the reception of a specific CNM header included in a CNM frame on any of the HDLC communication channels and responsive to the detection for setting the BCC calculator to a predefined state. The latter state corresponds to the state of the BCC calculator after a computation of BCC for the specific CNM header. Therefore the BCC calculator can proceed with computation of said BCC for the CNM frame.

摘要： A coding process, given a total number of available bits per unit time, allocates to each of a plurality of signal channels a number of bits proportional to information in the channel. The process is useful for transcoding BCPCM (Block Coded PCM) voice signals for lower bit rate and conserving transmission channel bandwidth.
摘要翻译： 给定每单位时间的总可用比特数的编码过程，向多个信道中的每一个分配与信道中的信息成比例的多个比特。 该过程对于代码转换BCPCM（块编码PCM）语音信号用于较低的比特率和节省传输信道带宽是有用的。
