Flexible Protection Mechanisms
The 2.5G transponder card provides flexible protection capabilities for both client and DWDM line interfaces, outlined in Table 1, enabling
support for a wide variety of network configurations required to deliver the various service-level agreements (SLAs) required by the customer
application.

Unprotected client and DWDM
line interfaces
line interfaces
These interfaces provide no client terminal interface or transponder card protection.
The client signal is transported over a single, unprotected transponder card. This
configuration would be suitable for transporting client payloads over the DWDM
network that are being protected via unidirectional-path switched ring/Subnetwork
Connection Protection (UPSR/SNCP) or Bidirectional Line Switch Ring/multiplex
switching protection-shared protection ring(BLSR/MSP-SPR) protocols.

1+1 protected client interfaces
These interfaces provide protection for both the client terminal interfaces as well as
the transponder cards. Two client interfaces operating 1+1 automatic protection
switching (APS) are passed through two transponder cards, with switching handled
between client terminal equipment interfaces.

Y-cable client interface
This interface provides transponder equipment and DWDM transport protection
without client terminal equipment interface protection. A single client interface is split
to two transponder cards. This feature is not supported on the protected version of the
transponder card.

Protected DWDM line interface
This interface provides network protection for a single client signal using the protected
version of the 2.5G transponder card. This card splits the outbound signal into two
wavelength paths. At the receiver end, the card selects the better of two input signals,
forwarding it to the client transmitter.
