3.3.3 EC1-12 Hosted by XCVT, XC10G, or XC-VXC-10G

All 12 STS-1 payloads from an EC1-12 card are carried to the XCVT, XC10G, or XC-VXC-10G card

where the payload is further aggregated for efficient transport. XCVT cards can host a maximum of

288 bidirectional STS-1s. The XC10G and XC-VXC-10G cards can host up to 1152 bidirectional

STS-1s.
