Stub lines (branches from the main line) should be avoided for data transmis-
sion speeds of more than 500 kbit/s. Except at end stations with termination, it
is recommended to always use plug connectors that permit two data cables to
be connected directly to the plug. This method allows the bus connector to be
plugged and unplugged at all times without interrupting data communication
between other stations.
