Circuit Source
Use the Circuit Source page to provision the circuit origination parameters. Provisionable parameters include Node, Slot, Port, specific STS, VT, DS1, and Member. The Node field appears for all circuit types. Slot, Port, STS, VT, DS1, and Member might appear, depending on the ONS node, circuit type, circuit size, the protection scheme, and the node and slot that are chosen. If a card, port, STS, or VT capacity is fully utilized, it does not appear in the menu.
For STS, STS-V, VT, and VT-V circuits, a secondary source check box appears, which you can use to create a secondary circuit source. For example, a path protected bridge/selector circuit entry point in a multi vendor path protected.
The following table describes the Circuit Source page fields and buttons.
 
Item
Description
Node
Sets the circuit source node.
Shelf
(Multishelf mode only) Filters circuits based on shelf.
Slot
Sets the slot used by the circuit. The card installed in the slot determines the availability of the Port, STS, VT, DS1, Member, and Edit Members fields.
Port
Sets the port used by the circuit. The Port field is available only when the slot contains a multiport card. If IEEE 802.17 RPR mode is enabled, the port drop-down list has RPR East or RPR West.
QinQ Settings
(SVLAN circuit only) Displays the QinQ settings page.
STS
Sets the STS used by the circuit.
VT
Sets the VT used by VT circuits.
DS1
Sets the DS-1 used by VT circuits.
Member
Displays the STS/VT used by the VCAT circuit members. This field is displayed only for CE-MR-10 card and if you have chosen Manual option in the Card tab.
Edit Members
Click to select a specific STS/VT for the VCAT circuit members.
Use Secondary Source
(STS, STS-V, VT, and VT-V circuits only) If checked, displays Node, Slot, Port, STS, and VT fields so you can define a secondary circuit source.
OCHNC Lines
Displays the aggregation ports (In and Out) facing the line through which the circuit will be routed.
Back
Displays the Circuit Attributes page.
Next
Displays the Circuit Destination page or the OpenVcat Destinations page (if you have chosen the Open VCAT option in the Circuit Attributes: STS VCAT Circuit/Circuit Attributes: VT VCAT Circuit page).
Cancel
Cancels circuit creation.
Help
Displays context-sensitive help.
