Circuit Source


Use the Circuit Source page to provision the circuit origination parameters. Provisionable parameters include Node, Slot, Port, specific synchronous transport signal (STS), virtual tributary (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 unidirectional path switched ring (UPSR) bridge/selector circuit entry point in a multivendor UPSR.

The following table describes the Circuit Source page fields and buttons.

Item

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.

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.
