8.13 Y-Cable and Splitter Protection
Y-cable and splitter protection are two main forms of card protection that are available for TXP and MXP 
cards, and for the GE_XP and 10GE_XP cards when they provisioned in TXP or MXP mode. Y-cable 
protection is provided at the client port level. Splitter protection is provided at the trunk port level. 
Note GE_XP and 10GE_XP use VLAN protection when they are provisioned in Layer 2 over DWDM mode. 
For information, see the “8.11.8  Layer 2 Over DWDM Protection” section on page 8-65. The ADM-10G 
card uses path protection and 1+1 protection. For more information, see the “8.12.10  Protection” 
section on page 8-73.
