Considerations for Using Y-Cable Based Line Card Protection

The following considerations apply when considering the use of line card protection:

•Y-cable line card protection does not protect against failures of the client equipment. To protect

against client failures, ensure that protection is implemented on the client equipment itself.

•A fully provisioned single shelf configuration can support up to 4 channels with line card protection

using transponder line cards. A fully provisioned multiple shelf configuration can support up to

32 channels in line card protection mode.

For more information about multiple shelf nodes, see Chapter8, “Configuring M ultipl e Shelf

Nodes.”

•Y-cable line card protection supports revertive behavior. With revertive behavior, the signal

automatically switches back to the working path after the signal failure has been corrected. The

default behavior is nonrevertive.

•To simplify system management, terminate the client signal on line cards that support the same

channel. In this way the client signal maps to the same WDM wavelength on both the working and

protection paths.

Caution Do not configure y-cable protection with Sysplex CLO, Sysplex ETR, or ISC compatibility protocol

encapsulation, or with the OFC safety protocol.
