If this test aborts or fails, it is impossible to determine from this test alone whether
the defective DATA-CHL is the target DATA-CHL or the arbitrarily chosen
DATA-CHL, or if the problem lies with the DATA-CON, TDM Bus, or Tone-Clock
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.
