Abstract
Digital cellular telephone with a variable rate vocoder is used with a number of different classes of service. A first class of service provides always constant bit rate to the telephone. A second class of service is the variable bit rate which changes the class of service depending on the traffic on the system. A third class of service is always-degraded service at a presumable lower price.
