11.11 Section and Path Trace
SDH J1 and J2 path trace are repeated, fixed-length strings composed of 64 consecutive bytes. You can
use the strings to monitor interruptions or changes to circuit traffic. The STM64-XFP and MRC-12 cards
support J0 section trace.
that are not listed in the table do not support the J1 byte.

If the string received at a circuit drop port does not match the string the port expects to receive, an alarm
is raised. Two path trace modes are available:

Automatic—The receiving port assumes that the first string it receives is the baseline string.
Manual—The receiving port uses a string that you manually enter as the baseline string.
