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.
