If you configure the primary clock source as the Port 2 loop and the secondary
clock source as the Port 1 loop, both clocks fail, and the following messages
appear in the log:
# 62: mm/dd/yy 10:44:50.734 WARNING SLOT 3 DS1E1 Code: 14
Connector COM2 Loss of signal failure.
# 63: mm/dd/yy 10:44:50.734 INFO SLOT 3 DS1E1 Code: 23
Primary and Sec clocks unoperational - Switching to Internal Clock
Source.
The following message appears if you mismatch the line coding. In this example,
the line coding of one side is AMI and the other is B8ZS (binary eight zeros
substitution).
# 234: mm/dd/yy 09:01:43.121 INFO SLOT 2 DS1E1 Code: 24
Connector COM1 B8ZS code received on port configured for AMI.
If you set the Line Type to ESF, many messages indicate bipolar violations on the
side configured for AMI.
