Result Description/Recommendation
4 ABORT For this test, an Error Code of 4 can have 1 of 2 different meanings:
a. The target DATA-CHL is busy and, therefore, not available for use.
b. Internal system error
Note the results of Tests #110 and #111 in the Short Test Sequence for the 
target DATA-CHL. If the results of Tests #110 and #111 are both PASS, then 
there is a high probability that the target DATA-CHL is not defective. 
Proceed with the remaining steps only if it is necessary to completely test 
the target DATA-CHL:
1. Determine if the target DATA-CHL is in use for some other function (that 
is, CDR Link, System Printer Link, Journal Printer Link, PMS Link, or 
secondary administration terminal connection) as described previously 
in the "Status of network Control Data Channels" section. If so, check for 
errors on the function that is using the DATA-CHL. If there are no errors, 
there is a high probability that the DATA-CHL is not defective. Proceed 
with the remaining steps only if it is necessary to completely test the 
target DATA-CHL.
2. If the target DATA-CHL is in use for some other function, busyout the 
function (CDR Link, System Printer Link, Journal Printer Link, PMS Link) 
or the DATA-CHL (secondary administration terminal connection only).
3. Retry the command at 1-minute intervals a maximum of 5 times.Restore 
any busied out CDR, System Printer, Journal Printer, or PMS Link to 
service before moving on to another activity.
