criteria to continuously monitor the incoming signal’s

amplitude and timing characteristics to determine

when and if to assert the internal carrier sense.

For these reasons, it is crucial that the values and

tolerances of the external components be as specified.

Several manufacturers produce a module that com-

bines the functions of the transmit and receive filters

and the pulse transformers into one package.
