Chapter 10 Circuits and Tunnels
10.3 Cross-Connect Card Bandwidth
Figure 10-2 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.
10.3 Cross-Connect Card Bandwidth
XC10G cards support high-order cross-connections (VC4 and above at STM-1, STM-4, STM-16, and
STM-64 signal rates). The XC10G does not support any low-order circuits such as VC-11, VC-12, and
VC3. The XC10G card cross connects standard VC4, VC4-4c, VC4-16c, and VC4-64c signal rates and
nonstandard VC4-2c, VC4-3c, and VC4-8c signal rates, providing a maximum of 384 x 384 VC4
cross-connections. Any VC4 on any port can be connected to any other port, meaning that the VC
cross-connection capacity is nonblocking. The XC10G card manages up to 192 bidirectional VC4
cross-connects.
VC4 tunnels must be used with the E3-12 and DS3i-N-12 cards to transport VC3 signal rates. Three ports
form a port group. For example, in one E3-12 or one DS3i-N-12 card, there are four port groups: Ports
1 to 3 = PG1, Ports 4 to 6 = PG2, Ports 7 to 9 = PG3, and Ports 10 to 12 = PG4.
Note In SDH Software R3.4 and earlier, the XC10G does not support VC3 circuits for the E3-12 and
DS3i-N-12 cards. You must create a VC tunnel. Refer to the Cisco ONS 15454 SDH Procedure Guide
for more information.
