Running a C7BERT
To run link fault sectionalization (LFS) the SOC option TEL0007 must
have the RTU set to "Y" and the state set to "on".
If link fault sectionalization (LFS) is activated, an anomaly in the
NT9X78BA and NT9X78CA cards can cause latch past to occur. When
the last DS0DP is a BA or CA paddle board, LFS may latch past the last
DS0DP link.For example, if the fifth and last device in a link is a BA or
CA card, LFS may latch the sixth or seventh DS0DP.Before running this
procedure, check the number and type of devices on a link. This
information helps reduce the link diagnosis time.

If you perform a remote loopback, inform a person at the far-end office that
• you will busy and deactivate the link, and
• the person must busy and deactivate the link at their end
