Abstract
A muldem (100) includes a transmit multiplexer section (103, 104) combining a variety of low speed and intermediate speed digital data inputs into a single high speed data output. A monitor (101) is provided for testing data path failures through the muldem (100) by comparing the latter's input and output. The monitor (101) includes comparing means (806, FIGS. 13a and b) which accepts both low and intermediate speed data from the inputs for comparison against the high speed data from the output.
