XC10G Cross-Connect Card
4.9 XC10G Cross-Connect Card
New to Software R3.1 is the XC10G card (Figure 4-9), which cross-connects STS-12, STS-48, and
STS-192 signal rates. The XC10G allows up to four times the bandwidth of current XC and XCVT cards.
The XC10G provides a maximum of 1152 STS-1 cross-connections. Any STS-1 on any port can be
connected to any other port, meaning that the STS cross-connections are non blocking.
Figure 4-9 shows the XC10G faceplate and block diagram. Figure 4-10 on page 4-28 shows the
cross-connect matrix.
Figure 4-9 XC10G faceplate and block diagram
The XC10G card manages up to 336 bidirectional VT1.5 ports and 576 bidirectional STS-1 ports. The
TCC+ assigns bandwidth to each slot on a per STS-1 or per VT1.5 basis.
Either the XC10G, XCVT, or XC is required to operate the ONS 15454. You can establish cross-connect
(circuit) information through the Cisco Transport Controller (CTC). The TCC+ establishes the proper
internal cross-connect information and sends the setup information to the cross-connect card.
Caution Do not operate the ONS 15454 with a single TCC+ card or a single XC10G/XCVT/XC card installed.
Always operate the shelf with one working and one protect card. Duplex cards must be the same type.
