Circuit Source
Use the Circuit Source page to provision the circuit origination parameters. Provisionable parameters include Node, Slot, Port, specific STS, VT, and DS1. The Node field appears for all circuit types. Slot, Port, STS, VT, and DS1 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 so you can create a secondary circuit source, for example, a UPSR bridge/selector circuit entry point in a multivendor UPSR.
The following table describes the Circuit Source page fields and buttons.

Description
|
Node
|
Sets the circuit source node.
|
Slot
|
Sets the slot used by the circuit. The card installed in the slot determines the availability of the Port, STS, VT, and DS1 fields.
|
Port
|
Sets the port used by the circuit. The Port field is available only when the slot contains a multiport card. If 802.17 RPR mode is enabled, the port drop-down list has RPR East or RPR West.
|
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.
|
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.
|
Cancel
|
Cancels circuit creation.
|
Help
|
Displays context-sensitive help.
