When a pretrip occurs on a line that connects to an LCM, a LINE138 log is
output. A LINE138 log identifies the call that was routed to a treatment. An
example of a LINE138 log follows.

After two pretrips occur, the line is scheduled for a diagnostic. If the
diagnostic fails, a LINE101 log is generated. An example of a LINE101 log
follows.

Pretrip on 4FR lines
The command string PRETRIP 4FR ENABLE is used to reduce ring pretrip
occurrences on long loop length 4FR lines served from the posted LCM or
all LCMs in the posted set. The effect of this command is not immediate
and will not be realized until the next RTS of the LCM. You must enter one
of the following actions with the command string PRETRIP 4FR.
ENABLE – This extends 4FR line ring filter timing.
DISABLE – This returns to non-extended 4FR line ring filter timing.
The following optional parameters can be entered with either of the previous
actions.
ALL – This results in the selected action being applied to all LCMs in
the posted set.
NOWAIT – This option prevents waiting for confirmation that a
command has been completed.
