4B72I cuu xx/ww tttt and additional information
Cause: This message, in one of four formats, provides the results of a scan of the error file of
an IBM 2715 Transmission Control Unit. The scan occurs when:
· eight errors (the threshold value) occur for one area station attached to the 2715, or
· a manual request is made at the 2715, the 2740 attached to the 2715, or the console
keyboard.
cuu the address of the communications line;
tttt the time (decimal 0001 to 2400 in the 24-hour clock system) of the error scan;
ww the address of a particular adapter within the 2715 (in hex);
xx the address of the area station for which the error scan is reported (in hexadeci-
mal);
yy the address of the device where the errors occurred (in hexadecimal).
zzzz the time (decimal 0001 to 2400 in the 24-hour system) that one group of error data
was recorded on the 2715 disk.
Each message text follows with an individual explanation.
Programmer Action: none.
Operator Action: none.
format 1:
cuu xx tttt yy ERS=n
Cause: Five or more of the eight errors at an area station occur on one device. n is the
number of errors (from 5 to 8) that occurred on device yy.
System Action: Processing continues.
Programmer Action: none.
Operator Action: none.
format 2:
cuu xx tttt THRESH'D
Cause: Eight errors (the threshold value) occur at area station xx, but not one device attached

Programmer Action: none.
Operator Action: none.
format 3:
cuu xx tttt yy eeee zzzz yy eeee zzzz yy eeee zzzz yy eeee zzzz
Cause: An error scan is manually requested for an area station. This message appears twice
in succession and the two messages provide error information for the eight most recent errors
at area station xx. eeee is the error data (in hexadecimal) for device yy.
System Action: Processing continues.
Programmer Action: none. 4
Operator Action: none.
format 4:
cuu ww tttt eeeeee zzzz eeeeee zzzz eeeeee zzzz eeeeee zzzz

at adapter ww. eeeeee is the error data (in hexadecimal) for adapter ww.
System Action: The message is printed on the master console, the teleprocessing console, or
the system maintenance console, depending on the routing code included in the error scan
message sent by the 2715 adapter. Normal processing then resumes.
