  The communications activity is done in "system jobs" [SYS jobs] which 
remain active irrespective of the /restricted state/ status.  The ENDSYS 
& ENDSBS *ALL requests will end all "subsystem [monitor] jobs" [SBS 
jobs] and all jobs within each subsystem, except the console job in the 
controlling subsystem.

  To prevent communications activity from taking memory and CPU during 
a system backup [or reclaim, or other /dedicated/ activity, vary off all 
communication resources\lines [an exception would be what resource the 
console requires to communicate].  Increasing the history log size and 
holding all access path rebuilds would be other activity to precede such 
activities to ensure the best of /dedicated/ operations.
