Data Channel Crosstalk Test (#110)
This test verifies the integrity of the entire DATA-CHL, that is, the software, dual
port RAM, and hardware that composes it. However, unlike the Remote
Maintenance Loop Around Test (#109), this test only involves the single
DATA-CHL that is the target of the test. A loop around connection is established
over the TDM Bus from the DATA-CHL back to itself. Data is looped over the
connection in each direction, that is, the DATA-CHL is tested as both a sender of
data and a receiver of data. The test checks that the data received by the
DATA-CHL is the same as the data that was sent by the DATA-CHL.
Because it establishes a loop around connection from the Network Control
DATA-CHL back to itself across the TDM Bus, this test does more than just verify
the integrity of the target DATA-CHL. It also verifies the integrity of the TDM Bus
and Tone-Clock circuit pack (by sending and receiving data).
If this test aborts or fails, it is impossible to determine from this test alone whether
the target DATA-CHL is defective or if the problem lies with the TDM Bus, or
Tone-Clock circuit pack. The results of running Tests #107, #108, and #111 on the
DATA-CHL can be used to determine whether the target DATA-CHL is defective.
NOTE:
If an Error Code is encountered that recommends that an CDR Link, System
Printer Link, PMS Log Printer, Wakeup-Log Printer Link, and/or PMS Link be
busied out, restore each busied-out link to service according to the
PRI-CDR/SEC-CDR (PRI-CDR Link), SYS-PRNT, or PMS-LINK
Maintenance documentation, respectively, before concluding work on the
problem.

Description/Recommendation
If the result of Test #107 is PASS and the result of Test #108 is PASS, then
the target DATA-CHL is defective.
Issue the remove data-module <ext> for the target DATA-CHL to
remove it from operation.
Replace the Processor circuit pack at your earliest convenience. After
the Processor circuit pack has been replaced, its Time-of-Day clock
must be set using the set time command.
8. Restore any busied out CDR, Journal Printer, System Printer, or PMS
Link to service before moving on to another activity.
The target DATA-CHL, Processor circuit pack, TDM Bus (TDM-BUS), and
Tone-Clock circuit pack (TONE-BD, TONE-PT, TDM-CLK) are functioning.
Connections can be established over the DATA-CHLs.
