11.3 Cross-Connect Card Bandwidth
A notation within or by the squares or selector pentagons on each node indicates switches and loopbacks,
including:
• F = Force switch
• M = Manual switch
• L = Lockout switch
• Arrow = Facility (outward) or terminal (inward) loopback
Figure 11-2 shows an example of a 2F-PCA circuit with a card in terminal loopback in the Edit Circuits
window.

Move the mouse cursor over nodes, ports, and spans to see tooltips with information including the
number of alarms on a node (organized by severity), port service state, and the protection topology.
Right-click a node, port, or span on the detailed circuit map to initiate certain circuit actions:
• Right-click a unidirectional circuit destination node to add a drop to the circuit.
• Right-click a port containing a path trace capable card to initiate the path trace.
• Right-click an SNCP span to change the state of the path selectors in the SNCP circuit.
11.3 Cross-Connect Card Bandwidth
The XC-VXL-10G, XC-VXL-2.5G, and XC-VXC-10G cards support both low-order and high-order
circuits, although only the XC-VXC-10G card supports VC-11 (low-order) circuits. The XC-VXL-10G
and XC-VXL-2.5G cards manage up to 192 bidirectional STM-1 cross-connects, 192 bidirectional E-3
