The power LED on the
VideoJet X.21
is the only display that
supplies information about the connection status. But it can be
monitored with the terminal program included in the scope of sup-
ply. More detailed information is given in Chapter 5. Most of the
DCEs (data circuit-terminating equipment) of an X.21 leased line
are also equipped with a display that indicates whether data are
being transmitted through the X.21 port.
