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