Change Card Settings
This chapter explains how to change transmission settings on cards in a CiscoONS15600SDH.
Before You Begin
As necessary, complete the "NTP-F49 Document Existing Provisioning" procedure.
Before performing the following procedures, investigate all alarms and clear any trouble conditions. Refer to the CiscoONS15600SDH Troubleshooting Guide as necessary.
This section lists the chapter procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).
•
F76 Modify Line and Status Thresholds for Optical Ports—As needed, complete this procedure to change line (drop) and threshold settings for all STM-N cards.
NTP-F76 Modify Line and Status Thresholds for Optical Ports
|
Purpose
|
This procedure changes line settings (line type, coding, and length), line status (in service or out of service), and performance monitoring (PM) thresholds for STM-16 and STM-64 cards.

Step1 Complete the "DLP-F36 Log into CTC" task at the node where you want to change the settings. If you are already logged in, continue with Step 2.
Step2 Complete the "NTP-F88 Back Up the Database" procedure on page14-3.
Step3 On the shelf graphic, double-click the STM-N card that you want to provision. The card view appears.
Step4 Click the Provisioning > MS tabs.
Step5 As needed, provision the options in Table11-1 for each STM-N port.

Provides Sync
|
Indicates that the port has been provisioned as a network element timing reference on another node (ONS15600SDH, ONS15454, ONS15327, ONS 15600, or ONS 15454 SDH).

Enables synchronization status messages (S1 byte), which allow the node to choose the best timing source.
|
•Yes (checked, default)

|
|
Send Do Not Use
|
When checked, sends a DUS (do not use) message on the S1 byte
|
•Yes (checked)
•No (unchecked; default)
|
|
MS-SPRing Ext. Byte
|
Chosen extended byte carries information that governs MS-SPRing protection switches.
|
•K3

|
State
|
Places port in or out of service.
|

Type
|
Defines the port as SDH.
|
•SDH (default)
|
Step6 Click Apply .
Step7 Click the Qos Thresholds subtab. The default selection is Near End, 15 Min, and MS ( Figure11-1).

Step8 As needed, complete the following:
a. Click MS , RS , Path, or Physical to provision the line, section, path, and physical options in Table 11-2 for each STM-N port.
b. Change the selection to Near End/Far End, 15 Min/1Day as necessary.
c. Click Refresh to view or modify the thresholds for each selection.

Set OPR
|
Setting the optical power received (OPR) establishes the received power level as 100percent. If the receiver power decreases, then the OPR percentage decreases to reflect the loss in receiver power. For example, if the receiver power decreases 3 dB, the OPR decreases 50 percent.
