Installing the 32WSS-L Card in the Cisco ONS 15454 SONET/SDH
Product Name: 15454-WSS-L
This document provides a card description, specifications, and installation procedure for the dense wavelength division multiplexer (DWDM) 32WSS-L card. The 32WSS-L card is compatible with Cisco ONS 15454 SONET (ANSI) and Cisco ONS 15454 SDH (ETSI) shelf assemblies. Use this document in conjunction with the Cisco ONS 15454 DWDM Procedure Guide when working with 32WSS-L cards.

32WSS-L Card Description
The 32-Channel Wavelength Selective Switch L-Band (32WSS-L) card performs channel add/drop processing within the ONS 15454 DWDM node. The 32WSS-L works in conjunction with the 32DMX-L to implement ROADM functionality within the L band (1570 to 1620 nm). The 32WSS-L card is well suited for use in networks that employ DS fiber or SMF-28 single-mode fiber. Equipped with ROADM functionality, a DWDM node can be configured to add or drop individual optical channels using Cisco Transport Controller (CTC), Cisco MetroPlanner, and Cisco Transport Manager (CTM).
An ROADM node utilizes two 32WSS-L cards (two slots each) and two 32DMX-L cards (one slot each), for a total of six slots in the chassis. For a diagram of a typical ROADM configuration, see the Cisco ONS 15454 DWDM Reference Manual. The two-slot 32WSS-L card can be installed in Slots 1 and 2, 3 and 4, 5 and 6, 12 and 13, 14 and 15, or 16 and 17.
The 32WSS-L has six types of ports:
•
•
•
•
•
•
A terminal node can be configured using only a 32WSS-L card and a 32DMX-L card plugged into the east or west side of the shelf.

Block Diagrams
Figure 2 provides a high-level functional block diagram of the 32WSS-L card.
Figure 2 32WSS-L Block Diagram
Aggregate optical signals that enter the EXP RX and COM RX ports are processed in two ways. The optical processing stages are shown in Figure 3, which provides a detailed optical functional diagram of the 32WSS-L card.
Figure 3 32WSS-L Optical Functional Diagram
The EX PORT and COM PORT operate as follows:
•
The incoming optical signal is received at the EXP RX port from the other 32WSS-L module within the NE. The incoming aggregate optical signal is demultiplexed into 32 individual wavelength components, or channels. Then each channel is individually processed by the optical switch, which does add/pass-through processing. Under software control, the switch either selects the optical channel coming in from the demultiplexer (the pass-through channel) or it selects the external ADD channel. If the ADD port channel is selected, the optical signal coming from the demultiplexer is blocked, and the ADD channel is transmitted in its place.
After the optical switch stage, all of the channels are multiplexed together into an aggregate optical signal, which is sent out on the COM TX port. The output is typically connected to an OPT-AMP-L (in the event a booster amplifier is needed) or to an OSC-CSM (if no amplification is needed).
•
The incoming optical signal received at the COM RX port is applied to the optical splitter within the 32WSS-L card. Channels that are designated to be dropped are diverted optically to the DROP TX port by the splitter. The DROP TX port on the 32WSS-L is typically connected to the COM RX port of the 32DMX-L where the drop channels are dropped. Channels that are not dropped pass through the optical splitter and flow out of the EXP TX port of the 32WSS-L card. This optical signal is typically connected to the other 32WSS-L module within the NE.
Power Monitoring
Physical photodiodes P1 through P69 monitor the power for the 32WSS-L card. The returned power level values are calibrated to the ports as shown in Table 1.
Channel Plan
The 32WSS-L card uses 32 channels on the ITU 100-GHz grid in a banded configuration (see Table 2).
32WSS-L Card Level Indicators
Table 3 describes the three card-level LED indicators on the 32WSS-L card.
32WSS-L Port-Level Indicators
You can find the status of the 32WSS-L card's ports using the LCD screen on the ONS 15454 ANSI fan-tray assembly. Use the LCD to view the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot.
The 32WSS-L card has five sets of ports located on the faceplate. COM RX is the line input, COM TX is the line output, EXP RX is the port where a channel can be added or passed through, EXP TX is the port that passes through the channels that are not dropped, and DROP TX is the port for the dropped channels. The xx.x to yy.y TX ports represent the four groups of eight channels ranging from the xx.x wavelength to the yy.y wavelenth according to the channel plan.
32WSS-L Card Specifications
The 32WSS-L card optical specifications are listed in Table 4.

Reporting Security Problems in Cisco Products
Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you might have identified a vulnerability in a Cisco product, contact PSIRT:
•
An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.
•
In an emergency, you can also reach PSIRT by telephone:

In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.
Cisco Technical Support & Documentation Website
The Cisco Technical Support & Documentation website provides online documents and tools for troubleshooting and resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, at this URL:
http://www.cisco.com/techsupport
Access to all tools on the Cisco Technical Support & Documentation website requires a Cisco.com user ID and password. If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
