Abstract
The invention relates to a method and equipment for network independent clocking in a telecommunication system, particularly in data transmission where the maximum data rate on a traffic channel is equal to the user data rate. In the invention a transmitter compares the network independent clock and the network clock to detect a slip and, upon detecting a slip, performs compensation of the network independent clock by changing the number of the redundant bits in user data. The user data is transmitted through a traffic channel to a receiver. The receiver, upon detecting the network independent clock compensation in the received user data, restores the original redundancy and temporarily adjusts the network independent clock so as to compensate for the change caused by the restoration of the redundancy in the outbound user data stream.
