In normal operation, over good quality communication channels, the error rate
(ratio of total line errors sent or received to total frames sent or received)
should be low, but is unlikely to be zero, except for a recently initialized
DECmux II unit.
On poor quality communications lines, the error rates will be high and will have
significant impact on the total link throughput, due to the error correction pro-
tocol. However, even on very poor quality lines, the DECmux II unit and
MUXserver 100 will present error free transmission to the asynchronous links.
