2.5.1 XC10G Functionality
The XC10G card manages up to 672 bidirectional VT1.5 ports and 1 152 bidirectional STS-1 ports. The
TCC2/TCC2P cards assign bandwidth to each slot on a per STS-1 or per VT1.5 basis.
Two cross-connect cards, installed in Slots 8 and 10, are required to operate the ONS 15454. You can
establish cross-connect (circuit) information through the CTC. The cross-connect card establishes the
proper internal cross-connect information and sends the setup information to the cross-co nnect card.
The XC10G card provides:
• 1152 STS bidirectional ports
• 576 STS bidirectional cross-connects
• 672 VT1.5 ports via 24 logical STS ports
• 336 VT1.5 bidirectional cross-connects
• Nonblocking at STS level
• STS-1/3c/6c/12c/48c/192c cross-connects
