The Clip Summary screen displays the configuration of the selected CLIP module (Figure 3-2). The Clip Summary screen is divided into three areas. The General area displays the operating state of the CLIP module and the data rate. The DWDM Side area describes the alarm status of the DWDM side, the optical paths, the optical coupling ratio, and the switch mode.
The information available on the Summary screen varies, depending on whether the Summary screen is associated with a CLIP module configured as protected or unprotected. Figure 3-2 shows the Summary screen for a protected CLIP. The Summary screen for unprotected clip modules does not show the Switch Mode or Standby Path fields.
The following fields on the Summary screen can be edited by the operator:
The General area of the Clip Summary screen describes general parameters that apply to the CLIP module. The values for the Data Rate field can be changed by the operator. Table 3-5 describes the parameters found in the General area of the CLIP Module Summary screen.
| Parameter | Value |
|---|---|
Network Element Status |
|
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. |
Follow these steps to change the data rate for the selected CLIP module:
Step 2 Select the desired data rate from the list. Table 3-5 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.
The procedure for changing the data rate is complete.
| Parameter | Value |
|---|---|
OC-3/STM-1 | The selected CLIP module will transmit at the bit rate of 155 Mbps. |
OC-12/STM-4 | The selected CLIP module will transmit at the bit rate of 622 Mbps. |
OC-48/STM-16 | The selected CLIP module will transmit at the bit rate of 2.5 Gbps. |
Gigabit Ethernet | The selected CLIP module will transmit data at the rate of approximately 1.25 Gbps. |
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.
| Parameter | Value |
|---|---|
DWDM Status |
|
Switch Mode | 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. Section 3.2.4 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:
In an unprotected system the following values are available:
|
Follow these steps to change the switch mode for the selected CLIP module:
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.
| 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. |
forced_b | Forces traffic to the B side. |
automatic | Automatically switches traffic to the standby path when the active path input signal is lost. The switch is non-revertive. |
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. Table 3-9 describes the Client Side parameters.
