Manage Circuits
This chapter explains how to manage Cisco ONS 15327 electrical, optical, and Ethernet 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.
Before You Begin
To create circuits, see "Create Circuits and VT Tunnels."
To clear any alarm or trouble conditions, refer to the Cisco ONS 15327 Troubleshooting Guide.
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).

Step 1 Complete the "DLP-B60 Log into CTC" task at the node where you want to view the cross-connect card resource usage. If you are already logged in, continue with Step 2.
Step 2 Click the Maintenance > Cross-Connect > Resource Usage tabs.
Step 3 In the Summary section of the Resources Usage tab, view the following information:
•STS-1 Matrix—Provides the percent of the XTC cross-connect STS-1 path resources that are used. There are 288 STS-1 paths available.
•VT Matrix Ports—Provides the percent of the XTC cross-connect Virtual Tributary (VT) matrix ports that are used. Each port is one STS in size, and each can transport 28 VT1.5s. 24 VT matrix ports are available.
•VT Matrix—Provides the percent of the VT matrix resources that are used. There are 672 available, which is the number of VT matrix ports (24) multiplied by the number of VT1.5s in an STS (28).
Step 4 In the VT Matrix Port Detail section, you can view details of the VT Matrix Port usage:
•Drop—Identifies the source slot, port, and STS.
•Tunnel Name—If the VT port is on a VT tunnel origination or termination port, the name of the VT tunnel appears in Tunnel Name.
•% Used—Shows the percent of the matrix port that is used. Each matrix port can carry 28 VT1.5s, so for example, if one STS carries seven VT1.5 circuits, the matrix port will be 25 percent used.
•Usage—Shows the port usage. For example, if one STS carries seven VT1.5 circuits, the matrix port will show 7 of 28 are used.

Step 3 Click the Circuits tab.
Step 4 Choose the bidirectional (2-way) circuit that you want to monitor and click Edit.
Step 5 Verify that the circuit name is no longer than 44 characters. Monitor circuits append a "_MON" to the circuit name. If the name is longer than 44 characters, edit the name in the Name field, then click Apply.
Step 6 In the Edit Circuit window, click the Monitors tab.
The Monitors tab provides ports that you can use to monitor the circuit.
Note The Monitors tab is only available when the circuit has a DISCOVERED status.
Step 7 In the Monitors tab, choose the monitor source port. The monitor circuit displays traffic coming into the node at the port you choose.
Step 8 Click Create Monitor Circuit.
Step 9 In the Destination panel of the Circuit Creation wizard, choose the destination node, slot, port, STS, VT, or DS1 for the monitored circuit.
Step 10 Click Next.
Step 11 In the Circuit Routing Preferences area, review the monitor circuit information. If you want the monitor circuit routed on a BLSR protection channel, click Protection Channel Access. If a confirmation dialog box appears, click OK to continue.
Step 12 Click Finish.
Step 13 In the Edit Circuit window, click Close. The new monitor circuit appears on the Circuits tab.
Stop. You have completed this procedure.
NTP-B79 Create a J1 Path Trace
Purpose

Prerequisite Procedures
|
•Circuits must exist on the network. See "Create Circuits and VT Tunnels" for circuit creation procedures.
•To route circuits on protected ports, you must create a protection group using the "B170 Create 1+1 Protection Groups" procedure or the "B126 Create a BLSR" procedure.
•When a roll involves two circuits, a data communications channel (DCC) connection must exist. See the "DLP-B253 Provision Section DCC Terminations" task.
•Use the "B199 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.
