Digital Control Problems
No GLI Control via LMF (all GLIs)
Follow the procedure in Table 6-15 to troubleshoot a GLI control via
LMF failure.
Table 6-15: No GLI Control via LMF (all GLIs)
Step Action
1 Check the 10Base-2 ethernet connector for proper connection, damage, shorts, or opens.
2 Verify the C-CCP backplane Shelf ID DIP switch is set correctly.
3 Visually check the master GLI connector (both board and backplane) for damage.
4 Replace the master GLI with a known good GLI.
No GLI Control through Span Line Connection (All GLIs)
Follow the procedures in Table 6-16 and Table 6-17 to troubleshoot GLI
control failures.
Table 6-16: No GLI Control through Span Line Connection (Both GLIs)
Step Action
1 Verify the C-CCP backplane Shelf ID DIP switch is set correctly.
2 Verify that the BTS and GLIs are correctly configured in the OMCR/CBSC data base.
3 Visually check the master GLI connector (both board and backplane) for damage.
4 Replace the master GLI with a known good GLI.
5 Check the span line inputs from the top of the frame to the master GLI for proper connection and
damage.
6 Check the span line configuration on the MGLI (see Table 5-4 on page 5-5).
Table 6-17: MGLI Control Good - No Control over Co-located GLI
Step Action
1 Verify that the BTS and GLIs are correctly configured in the OMCR CBSC data base.
2 Check the ethernet for proper connection, damage, shorts, or opens.
3 Visually check all GLI connectors (both board and backplane) for damage.
4 Replace the remaining GLI with a known good GLI.
