A method of bypassing vocoders in a digital mobile communication system, comprising the step of appending bypass mode data to data transmitted from a plurality of mobile stations, the bypass mode data instructing the vocoders not to perform encodingdecoding operations, and the step of transmitting the resultant data. When the discharge control FET receives this signal, it is connected and passes a discharge current. In one example, the module accesses the cache to create one or more packets including link state data.
