Abstract
Transmission quality assessment arrangement for a communication switching system wherein a stream of cells of information is transmitted from an input (I) to an output (O) over a same communication path. It is adapted, at the input, to insert in the cell stream test cells each having a tag indicative of its position in the resultant cell stream and to count, at the output, the position of each test cell in the latter cell stream. From the difference of the position counted and that stored in the leg of a test cell an indication of the number of added or lost cells--indicative of the transmission quality--is derived.
