Note For hardware specifications, see the “A.4.4  XC10G Card Specifications” section on page A-12.
The 10 Gigabit Cross Connect (XC10G) card establishes connections at the STS-1 and VT levels. The 
XC10G provides STS-192 capacity to Slots 5, 6, 12, and 13, and STS-48 capacity to Slots 1 to 4 and 14 
to 17. The XC10G allows up to four times the bandwidth of the XCVT cards. The XC10G provides a 
maximum of 576 STS-1 cross-connections through 1152 STS-1 ports. Any STS-1 on any port can be 
connected to any other port, meaning that the STS cross-connections are nonblocking.
Figure 2-5 shows the XC10G faceplate and block diagram.
