<p>The invention relates to a method for changing the data transfer rate in a certain part of a communications connection. The method is such that information is processed (410) using a processing method at a first point of the communications connection, the processed information, which has been transferred, is processed (440) using a restoration method at a second point of the communications connection, and the said processing and restoration methods are selected (411) from a certain set of methods. At the borders of consecutive parts, between the said first point and second point of the communications connection the data transfer rates used in adjacent parts are adapted (430) to one another. At first, information is transferred (401, 402) at certain first data transfer rates used in the individual parts. In at least one of the said parts the data transfer rate used is changed and, thereafter, information is transferred (403, 404) at certain second data transfer rates. The method according to the invention is characterized in that prior to changing the data transfer rate, the processing method is selected (450) so that it produces processed information at a rate which is not higher than the highest of the first and second data transfer rates.</p> |
