The General area of the Clip Summary screen describes general parameters that apply to the CLIP module. The values for the Protection Data Rate field can be changed by the operator. Table 3-5 describes the parameters found in the General area of the Clip Summary screen.


Table 3-5:
Clip Summary Screen—General
Parameter Value

Network Element Status

Uninit—The Maintenance Manager did not recieve any information from the selected CLIP module.

Normal—The selected CLIP module has not reported any alarms.

Warning—The selected CLIP module has reported a condition that exceeds a high warning or lower warning threshold value.

Minor—The selected CLIP module generated a minor alarm based on a condition that exceeds a high alarm or lower alarm threshold value.

Major—The selected CLIP module generated a major alarm based on a condition that exceeds a high alarm or lower alarm threshold value.

Critical—The selected CLIP module generated a critical alarm based on a condition that exceeds a high alarm or lower alarm threshold value.

Installed—The NE detects the physical presence of the CLIP module, but data from the CLIP module has not been uploaded yet. Possible causes include a faulty connection or lack of management of the CLIP.

Not_installed—The NE has lost contact with the CLIP module.

Undefined—An alarm was received but its content cannot be interpreted.

Protection

Yes—The selected CLIP module's traffic is protected on another circuit.

No—The selected CLIP module's traffic is not protected on another circuit.

Uploaded

Yes—When the CLIP was detected, all required data about the CLIP was successfully retrieved from the CLIP.

No—When the CLIP was detected, all required data about the CLIP was not successfully retrieved from the CLIP. To move the Uploaded state from No to Yes, you can manually select Upload from the Tools/Clip menu or right-click the specified CLIP and select Upload.

Note   If this parameter is set to No, the Network Element Status value will be Installed. Thereby the Status will not be recognized and there will be no status information in the Explorer View (tree control).

Data Rate

Describes the rate at which data is being transmitted in and by the ONS 15200 system. The operator can change this value. The "Changing the Data Rate" section describes the procedure for changing the data rate.

3.2.2 Changing the Data Rate

Follow these steps to change the data rate for the selected CLIP module:


Step 1   Open the Clip Summary screen and double-click the Data Rate value. The Set Value screen opens (Figure 3-4).

Step 2   Select the desired data rate from the list. Table 3-6 describes the data rate selections available.

Step 3   Click OK. The selected data rate appears on the Clip Summary screen. The change is effective immediately.


Figure 3-4: Set Value (datarate) window



Table 3-6: Data Rate Values
Parameter Value

OC-3

The selected CLIP module will transmit at a bit rate of 155 Mbps.

3.2.3 DWDM Side

The DWDM Side area of the Clip Summary screen describes parameters that apply to the ONS 15200 transmissions between CLIP modules. The values for the Switch Mode field can be changed by the operator. Table 3-7 describes the DWDM Side parameters.


Table 3-7:
Clip Summary Screen - DWDM SIde
Parameter Value

DWDM Status

  • Normal—The selected CLIP module has not reported any alarms.

  • Warning—The selected CLIP module has reported a condition that exceeds a high warning or lower warning threshold value.

  • Minor—The selected CLIP module generated a minor alarm based on a condition that exceeds a high alarm or lower alarm threshold value.

  • Major—The selected CLIP module generated a major alarm based on a condition that exceeds a high alarm or lower alarm threshold value.

  • Critical—The selected CLIP module generated a critical alarm based on a condition that exceeds a high alarm or lower alarm threshold value.

FDI Switch

Enable—If a protected CLIP module receives a Forward Defect Indication (FDI) alarm, it will automatically switch to the standby path.

Disable—If a protected CLIP module receives a FDI alarm, it will not switch to the standby path.


Caution   Setting this parameter to Disable could be traffic affecting if an FDI alarm is received.

Switch Mode

(Displayed only if the CLIP supports fiber protection.)

Displays the switching scheme assigned to the selected CLIP module. The operator can change this value.

The switching scheme selected determines how the ONS 15200 system will behave if the input signal is lost on the active path. The "Procedure: Change the Switch Mode" section describes the procedure for changing the switching scheme.

Active Path

Displays the primary path on which the CLIP module is receiving. In protected configurations, the active path can be either path_a or path_b.

Standby Path

(protected channel only)

Displays the secondary path on which the CLIP module is receiving. In the event of a disruption on the primary path, the system uses the signal received on the standby path. The standby path is always the opposite of the active path, if it exists.

Note   When switch mode is set to either forced_a or forced_b, there is no alternative standby signal. The system is forced to use either the a or b path.

Optical Coupling Ratio

Describes how the optical power is split between the A side and the B side of the system.

In a protected system the following values are available:

  • a90b10—90% of the optical power is allocated to the A side and 10% of the optical power is allocated to the B side.

  • a50b50—50% of the optical power is allocated to the A side and 50% of the optical power is allocated to the B side.

  • a10b90—10% of the optical power is allocated to the A-side and 90% of the optical power is allocated to the B side.

In an unprotected system the following values are available:

  • a100b0—100% of the optical power is allocated to the A side and 0% of the optical power is allocated to the B side.

  • a0b100—0% of the optical power is allocated to the A side and 100% of the optical power is allocated to the B side.

Procedure: Change the Switch Mode


Note   Switch mode is only available on protected channels.

Follow these steps to change the switch mode for the selected CLIP module:


Step 1   On the Clip Summary screen double-click the Switch Mode value (Figure 3-2). The Set Value window opens (Figure 3-5).


Figure 3-5: Set Value (dwdm.switchmode) window


Step 2   Select the desired switch mode from the list. Table 3-8 describes the selections available.

Step 3   Click OK. The value appears on the Clip Summary screen. The changes are effective immediately.


Table 3-8:
Switch Mode Values
Parameter Value

cond_a

Automatically selects path A as the primary path if the signal on the A side is present. If the signal is lost and power is present on the B side, the path switches. However, as soon as the A-side signal returns, the signal reverts to the A side.

cond_b

Automatically selects path B as the primary path if the signal on the B side is present. If the signal is lost and power is present on the A side, the path switches. However, as soon as the B side signal returns, the signal reverts to the B side.

forced_a

Forces traffic to the A side.

Note   If the switch mode is set to forced_a, traffic cannot revert to the B side if the A side fails.

forced_b

Forces traffic to the B side.

Note   If the switch mode is set to forced_b, traffic cannot revert to the A side if the B side fails.

automatic

Automatically switches traffic to the standby path when the active path input signal is lost. The switch is non-revertive.


3.2.4 Client Side

The Client Side area of the Clip Summary screen describes parameters that apply to the ONS 15200 transmissions between the selected CLIP module and the client equipment. Values in this section cannot be modified by the operator. The Client Alarm Status can be set to the follow values:

Figure 3-7: Clip Status screen (unprotected)


The Clip Status screen is divided into four areas: DWDM Side, Client Side, Environment, and DCN. The DWDM Side area lists the settings and current values of the signal from the DWDM side of the ONS 15200 system. Parameters listed in the Client Side area describes the quality of the signal received from the client equipment. The Environment area provides the board temperature and power of the CLIP module. The DCN area indicates any Control Area Network (CAN) or QPP alarms.
