NTP-A293 Create a J2 Path Trace
Provision the circuit source transmit string:
Step 7
On the detailed circuit map, right-click the circuit source port (the square on the left or right of the
a.
source node icon) and choose Edit J2 Path Trace (port) from the shortcut menu.
In the New Transmit String field, enter the circuit source transmit string. Enter a string that makes
b.
the source port easy to identify, such as the node IP address, node name, circuit name, or another
string. If the New Transmit String field is left blank, the J2 transmits a string of null characters.
Click Apply, then click Close.
c.
Provision the circuit destination transmit string:
Step 8
On the detailed circuit map, right-click the circuit destination port and choose Edit Path Trace from
a.
the shortcut menu.
In the New Transmit String field, enter the string that you want the circuit destination to transmit.
b.
Enter a string that makes the destination port easy to identify, such as the node IP address, node
name, circuit name, or another string. If the New Transmit String field is left blank, the J2 transmits
a string of null characters.
c. Click Apply.
Provision the circuit destination expected string:
Step 9
On the Circuit Path Trace window, enable the path trace expected string by choosing Auto or
a.
Manual from the Path Trace Mode drop-down list:
•
•
If you set the Path Trace Mode field to Manual, enter the string that the circuit destination should
b.
receive from the circuit source in the New Expected String field. If you set Path Trace Mode to Auto,
skip this step.
c. (Check box visibility depends on card selection.) Click the Disable AIS on C2 Mis-Match check
box if you want to suppress the alarm indication signal (AIS) when a C2 mismatch occurs.
d. Click Apply, then click Close.
Note
Provision the circuit source expected string:
Step 10
In the Edit Circuit window (with Show Detailed Map chosen), right-click the circuit source port and
a.
choose Edit Path Trace from the shortcut menu.
In the Circuit Path Trace window, enable the path trace expected string by choosing Auto or Manual
b.
from the Path Trace Mode drop-down list:
•
•
If you set the Path Trace Mode field to Manual, enter the string that the circuit source should receive
c.
from the circuit destination in the New Expected String field. If you set Path Trace Mode to Auto,
skip this step.

Auto—The first string received from the source port is automatically provisioned as the current
expected string. An alarm is raised when a string that differs from the baseline is received.
Manual—The string entered in the Current Expected String field is the baseline. An alarm is
raised when a string that differs from the Current Expected String is received.
It is not necessary to set the format (16 or 64 bytes) for the circuit destination expected string;
the path trace process automatically determines the format.
Auto—Uses the first string received from the port at the other path trace end as the baseline
string. An alarm is raised when a string that differs from the baseline is received.
Manual—Uses the Current Expected String field as the baseline string. An alarm is raised when
a string that differs from the Current Expected String is received.
