Chapter 7 Manage Circuits
NTP- D79 Create a J1 or J2 Path Trace
NTP-D79 Create a J1 or J2 Path Trace
Note
There are two types of J1 bytes, high-order (HO-J1) and low-order (LO-J1). The electrical cards support
LO-J1 (VC3). The optical cards support HO-J1 (VC4) and cannot monitor the LO-J1 byte. In addition,
the E1-42 card supports HO-J1 when the card is provisioned as an HO circuit endpoint.
Note
J1 path trace is available for VC3 and VC4 circuits. In ONS 15454 SDH Software R3.4 and earlier, you
can set the VC3 J1 transmit string on E3 and DS3i-N-12 cards, but VC3 is not monitored by STM-N
cards. J2 path trace is available for VC12 circuits.
Step 1
Complete the
“DLP-D60 Log into CTC” task on page 17-49
at a node on the network where you will
create the path trace. If you are already logged in, continue with Step 2.
Step 2
Complete the following tasks as needed:
•
As needed, complete the
“DLP-D264 Provision a J1 Path Trace on Circuit Source and Destination
•
As needed, complete the
“DLP-D137 Provision a J1 Path Trace on STM-N Ports” task on
.
•
As needed, complete the
“DLP-D367 Provision a J2 Path Trace on Circuit Source and Destination
Stop. You have completed this procedure.
Purpose
This procedure creates a repeated, fixed-length string of characters used to
monitor changes to circuit traffic.
Tools/Equipment
ONS 15454 SDH cards capable of transmitting and/or receiving path trace
must be installed. See
for a list of J1 path trace
cards. See
for a list of J2 path trace cards.
Prerequisite Procedures
J1 path trace can be provisioned on VC3 and VC4 circuits. J2 path trace
can be provisioned on VC12 circuits. See
Chapter 6, “Create Circuits and
for circuit creation procedures.
Required/As Needed
As needed
Onsite/Remote
Onsite or remote
Security Level
Provisioning or higher
