FAIL In the case of Error Code 40, the Crosstalk Test failed because the data
received over the connection did not match the d ata sent over the connection
(data was corrupted). In the case of Error Code 2000, 2003, and 2004, the
crosstalk test failed because the data looped over the connection was not
received (data was lost).
1. Determine which of the DATA-CHLs are 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 p reviously in
the ‘‘Status of Data Channels’’ section.
2. Note the test result for Test #111 in the Short Test Sequence for the target
DATA-CHL and refer to Steps 3 and/or 4 to determine the appropriate
actions to take based on those results.
3. If the result of Test #111 is PASS, then the most likely problem is that the
TDM Bus or Tone-Clock circuit pack is defec tive.
a. Check for the existence of TDM Bus (TDM-BUS) and/or Tone-Clock
circuit pack (TONE-BD, TONE-PT, and TDM-CLK) errors and alarms. If
they exist:
1. Refer to the corresponding Maintenance documentation to clear
the errors and alarms.
2. Repeat the test.
b. If TDM Bus (TDM-BUS) and/or Tone-Clock circuit pack (TONE-BD,
TONE-PT, and TDM-CLK) errors and alarms do not exist, investigate
the possibility that the target DATA-CHL, or the Pr o cessor circuit pack
is defective as described in Step 4.
