(Network view only) The Overhead Circuits tab allows you to view information about overhead circuits
on the network. Overhead circuits include DCC and IP tunnels, user data channels, and local and express orderwire (orderwire circuits require Alarm Interface Controller–International [AIC-I] cards). You can also create, delete, edit, and merge overhead circuits.

Displays the name of the circuit. You can edit the name by double-clicking the name, which opens the Edit Circuit window.

Displays the circuit source in the format: node/slot/port “port name”/STS/VT. (Port name appears in quotes.) Node and slot always display; port “port name”/STS/VT might display, depending on the source card, circuit type, and whether a name is assigned to the port. If the circuit size is a concatenated size (3c, 6c, 12c, etc.), STSs used in the circuit are indicated by an ellipsis, for example, “S7..9,” (STSs 7, 8, and 9) or S10..12 (STS 10, 11, and 12). Note the following:
• |
If the port is on an ONS 15600 Any Service, Any Port (ASAP) card, the port format is pluggable interface module ( PIM)-pluggable port module (PPM)-port number. |
• |
If the port is on an ONS 15454 MRC-12 card, the port format is PPM-port number. |
• |
If the port is on an ONS 15310-CL or ONS 15310-MA card and is not an optical port, the port format is port type-port number, for example, pEC1-1. If the port is a DS-1 port, the port number is not shown, for example, pDS1. |
|
|
Displays the circuit destination in same format as the circuit source.
|
|
Displays the number of internode links that constitute the circuit. Right-clicking the column displays a shortcut menu from which you can choose to show or hide circuit span detail.

|
|
|
|
Deletes the overhead circuit that is highlighted.
|
|
Merges multiple orderwire cross-connects created in older CTC releases into one network-level CTC circuit.
|
|
Displays the Circuit Name Search dialog box, to search for circuits based on circuit name.
|
|
Displays context-sensitive help.
