Circuits and Tunnels
This chapter explains how to create and administer Cisco ONS 15327 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 15327 cross-connect card capacities
•
Creating DCC tunnels to tunnel third-party equipment through ONS 15327 networks
6.1 Circuits Overview
You can create STS and VT1.5 circuits across and within ONS 15327 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, or STS-48c. Ethernet
circuits can be STS-1, STS-3c, STS-6c, or STS-12c. (To create Ethernet circuits see the
Circuit Configurations” section on page 9-6
•
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 15327
unidirectional path switched ring (UPSR) with third-party equipment UPSRs.
