Creating standard STS and VT1.5 circuits
Creating VT tunnels
Creating multiple drop circuits
Creating monitor circuits
Editing UPSR circuits
Creating path traces to monitor traffic
Reviewing ONS 15454 cross-connect card capacities
Creating DCC tunnels to tunnel third-party equipment through ONS 15454 networks
Create one-way, two-way, or broadcast circuits.
Assign user-defined names to circuits.
Assign different circuit sizes. STS circuits can be STS-1, STS-3c, STS-12c, STS-48c, or STS-192c.
Ethernet circuits can be STS-1, STS-3c, STS-6c, or STS-12c. (To create Ethernet circuits see the
"Provision a Shared Packet Ring" procedure on page
Route circuits automatically or manually.
Automatically create multiple circuits.
Require the circuit path to be fully protected.
Require protected source and destination cards and ports.
Define a secondary circuit source or destination that allows you to interoperate an ONS 15454
unidirectional path switched ring (UPSR) with third-party equipment UPSRs.
