7.1 Overview

7.1 Overview
You can create circuits across and within ONS 15454 nodes and assign different attributes to circuits.
For example, you can:
•
•
•
•
•
•
•
•
•
You can provision circuits at either of the following points:
•

7-2
Create one-way, two-way (bidirectional), or broadcast circuits.
Assign user-defined names to circuits.
Assign different circuit sizes.
Automatically or manually route circuits.
Automatically create multiple circuits with autoranging.
Provide full protection to the circuit path.
Provide only protected sources and destinations for circuits.
Define a secondary circuit source or destination that allows you to interoperate an ONS 15600 path
protection with third-party equipment path protection configurations.
Set path protection circuits as revertive or nonrevertive.
Before cards are installed. The ONS 15600 allows you to provision slot and circuits before installing
the traffic cards.
After you preprovision the small-form factor pluggables (SFPs) (also called provisionable port
modules [PPMs]).
Cards and SFPs are installed and ports are in service. Circuits do not actually carry traffic until the
cards and SFPs are installed and the ports are In-Service and Normal (IS-NR); Out-of-Service and
Autonomous, Automatic In-Service (OO-AU,AINS); or Out-of-Service and
Management, Maintenance (OOS-MA,MT). Circuits will carry traffic as soon as the signal is
received.
Name—The name of the circuit (user-assigned or automatically generated).
Type—For the ONS 15600, the circuit type is STS (STS circuit).
Size—The STS circuit size can be 1, 3c, 12c, 24c, 48c, or 192c. The STS circuit size for ASAP PPM
ports also includes 6c and 9c. For time slot availability on concatenated STSs, see the
"7.2.1 Concatenated STS Time Slot Assignments" section on page
Protection—The protection type; see the
Direction—The circuit direction, either two-way or one-way.
Status—The circuit status; for details, see the
Source—The circuit source in the format: node/slot/port/STS. If an ASAP PPM port is the circuit
source, the port format is PIM-PPM-port, where pluggable interface module (PIM) and PPM values
are 1 through 4 (for example, p1-1-1). PPMs have only one port.
