Simultaneous transfer of voice and data information using multi-rate vocoder and byte control protocol

摘要: A technique and method that efficiently simultaneously transfers both voice data information over a single communications link (11). The utilizes multi-rate vocoder (12) for providing at plurality of different rates. Accordingly, the may be dynamically adjusted during transfer to meet channel bandwidth requirements. also byte-control protocol inserting within stream by use escape (DLE) byte command (34). is inserted into an existing such transferred only upon demand when needed. This prevents useless information, as speaker silent and, thus, allows very efficient utilization system bandwidth.
