Method and apparatus of providing bit count integrity and synchronous data transfer over a channel which does not preserve synchronization

) And the synchronous data stream by it maintaining synchronous attribute media transmission of synchronous data stream flowing and maintain the end-to-end the synchronous and position of counting integrity synchronous data stream. The terminal device unit (100) for generating a rate voltage current, providing a communication unit (110). The communication unit (110) is generated the first data frame, comprising a constant rate voltage current first group of position and length value field. Producing the second data frame, comprising a constant rate voltage current second set of positions and length fields. Generating a data frame, comprising a constant rate voltage current a group of position and a field length value. A first, second and third data frame to the base station (118), a base station (118) is arranged between the first first group of positions to the moulded (150). Which is equal to the includes any maximum digital group of a base and a to the moulded (150). , And the base station (118) automatically according to the first field length value and a field length value determines the third data frame a certain the second set of position. The base station (118) rewrites forming (150) of the third group of positions the unnecessary method of. The unnecessary method of there is equal to the may include a to the maximum digital and second set of position difference of certain.
