Circuits and Tunnels
This chapter explains how to create and administer Cisco ONS 15454 circuits and tunnels, which
includes:
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
6.1 Circuits Overview
You can create STS and VT1.5 circuits across and within ONS 15454 nodes and assign different
attributes to circuits, for example:
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 “E
Series Circuit Configurations” section on page 9-14 or the “G1000-4 Circuit Configurations
section on page 9-30.)
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.
