circuit pack. The results of running Tests #107, #108, #110, and #111 on the
DATA-CHL can be used to determine whether the target DATA-CHL is defective.
Finally, recall from the description of that DATA-CHLs 1 and 2 share a common
Dual Port RAM (DPR) and TDM Bus interface hardware and DATA-CHLs 3 and 4
share a common DPR and TDM Bus interface hardware. Thus, if this test finds
that DATA-CHL 1 is defective, then DATA-CHL 2 is likely to be defective and vice
versa. Similarly, if this test finds that DATA-CHL 3 is defective, then DATA-CHL 4
is likely to be defective and vice versa.
NOTE:
If an Error Code is encountered recommending that an CDR, System
Printer, Journal Printer, and/or PMS Link be busied out, restore each busied
out link to service according to PRI-CDR/SEC-CDR (PRI-CDR Link),
SYS-PRNT (System Printer Link), JNL-PRNT (Journal Printer Link), or
PMS-PRNT/JNL-PRNT (PMS Printer Link) Maintenance documentation,
respectively, before concluding work on the problem.

Test
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.
