Manage Circuits

Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

This chapter explains how to manage Cisco ONS 15600 optical and overhead circuits.

Before You Begin

To create circuits, see Chapter 6, "Create Circuits."

To clear any alarm or trouble conditions, refer to the Cisco ONS 15600 Troubleshooting Guide.

This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).

1. E51 Locate and View Circuits—Complete as needed.

2. E52 Modify and Delete Circuits—Complete as needed to edit a circuit name, change the active and standby colors of spans, or change signal fail (SF) and signal degrade (SD) thresholds, reversion time, and payload defect indication-path (PDI-P) settings for path protection circuits.

3. E134 Modify and Delete Overhead Circuits—Complete as needed to change a tunnel type, repair an IP circuit, or delete overhead circuits.

4. E1 Create a J1 Path Trace—Complete as needed to monitor interruptions or changes to circuit traffic.

5. E55 Bridge and Roll Traffic—Complete as needed to reroute circuits without interrupting service.

6. E126 Reconfigure Circuits—Complete as needed to reconfigure circuits.

7. E127 Merge Circuits—Complete as needed to merge circuits.

Note To provision ONS 15600 circuits from an ONS 15454 and/or ONS 15327 node, the Cisco Transport Controller (CTC) version launched from the ONS 15454 or ONS 15327 must be Software R4.1 or later. Cisco recommends launching CTC from the ONS 15600 node before provisioning circuits.

Note During circuit provisioning in a network that includes ONS 15600s, ONS 15454s, and ONS 15327s, the ONS 15600 raises a temporary UNEQ-P alarm. The alarm clears when the circuit is complete.

Prerequisite Procedures

•Circuits must exist on the network. See Chapter 6, "Create Circuits" for circuit creation procedures.

•To route circuits on protected ports, you must create a protection group using the "NTP-E25 Create a 1+1 Protection Group" procedure on page 4-7 or the "NTP-E164 Create a BLSR" procedure on page 5-9.

•When a roll involves two circuits, a data communications channel (DCC) connection must exist. See the "DLP-E114 Provision Section DCC Terminations" task on page 17-14.

•Use the "E51 Locate and View Circuits" procedure to verify that the planned Roll To paths are in service. Verify that the planned Roll To and Roll From paths are not in the Roll Pending status, used in test access, or used in a loopback.
