Normally,  physical lines are attached to Channels.  An RSCS connection
or a VM PassThru line might connect to another machine at 9.6 Kb.
If the two machines are located close enough (usually <= 100 ft) a
CTCA can be used to connect the two machines,  allowing for a
much higher transfer rate.  There's also a Virtual CTCA.  A VCTCA,
which is software,  allows you to connect two "machines" residing
in the same physical box  (i.e. VM yo MVS).
