Circuits Filter


Use the Circuits Filter dialog box to filter the circuits that appear on the Circuits tab based on circuit type, status, protection, size, and other parameters.

Item

Description

Name

Allows you to filter circuits based on the complete or partial circuit name. If blank, circuit name is not used to filter circuits.

Direction

Filters circuits based on circuit direction. Valid entries are:

  • Any: Direction is not used to filter circuits.

  • 1-way: Displays only one-way circuits.

  • 2-way: Displays only two-way circuits.

OCHNC Dir

(ONS 15454 only) Filters dense wavelength division multiplexing (DWDM) optical channel network connections (OCHNCs) by direction:

  • East to West: Displays only east-to-west optical OCHNCs.

  • West to East: Displays only west-to-east OCHNCs.

OCHNC Wlen

(ONS 15454 only) Filters DWDM OCHNCs by wavelength. For example, choosing 1530.33 displays OCHNCs provisioned on the 1530.33-nm wavelength.

Status

Filters circuits by their status. Valid entries are:

  • Any: Displays circuits in any status.

  • DISCOVERED: Displays only circuits that have a complete path from source to destination.

  • PARTIAL: Displays only circuits missing a connection or span to form a complete path.

  • DISCOVERED_TL1: Displays only TL1-created or TL1-like CTC-created circuits.

  • PARTIAL_TL1: Displays only TL1-created circuit or a TL1-like CTC-created circuits that are missing a cross-connect or span to form a complete path.

See Circuit Statuses for more information about circuit statuses. (While other statuses are described in that table, filtering is only supported for DISCOVERED, PARTIAL, DISCOVERED_TL1, and PARTIAL_TL1 circuits)

State

Filters circuits by circuit service state. Valid entries are:

  • OOS: Displays only Out-of-Service (OOS) circuits.

  • IS: Displays only In-Service (IS) circuits.

  • OOS[PARTIAL]: Displays only circuits with cross-connects that are not all in the In-Service and Normal (IS-NR) service state.

See Circuit States for more information about circuit states.

Protection

Filters circuits by their protection. See Circuit Protection Types for more information about protection types and ONS nodes that support them. Valid entries are:

  • Any: Protection is not used to filter circuits.

  • 1+1: Displays only circuits that are protected by a 1+1 protection group.

  • 2F-BLSR: Displays only circuits that protected by two-fiber bidirectional line switched rings (BLSR).

  • 2F-PCA: Displays only circuits that are routed on a protection channel access (PCA) path on a two-fiber BLSR. (PCA circuits are not protected.)

  • 4F-BLSR: Displays only circuits are protected by a four-fiber BLSR.

  • 4F-PCA: Displays only circuits that are routed on a PCA path on a four-fiber BLSR. (PCA circuits are not protected.)

  • BLSR: Displays only circuits that are protected by a both a two-fiber and a four-fiber BLSR.

  • Splitter: Displays only circuits that have their source and destination on MXPP_MR_2.5G and TXPP_MR_2.5G cards. These cards provides splitter (line-level) protection.

  • N/A: Displays only circuits with connections on the same node that are not protected.

  • PCA: Displays only circuits that are routed on a PCA path on both two-fiber and four-fiber BLSRs. (PCA circuits are unprotected.)

  • Protected: Displays only circuits that are protected by diverse SONET topologies, for example, BLSR and unidirectional path switched ring (UPSR), or UPSR and 1+1 protection.

  • UPSR: Displays only circuits that are protected by a UPSR.

  • DRI: Displays only circuits that are protected by a BLSR or UPSR dual-ring interconnect (DRI).

  • Unknown: Displays only circuits with sources and destinations on different nodes if communication is down between the nodes. This protection type appears if not all circuit components are known.

  • Unprot: Displays only circuits with sources and destinations on different nodes that were created as fully protected circuits but are no longer protected due to a system change, such as a traffic switch.

  • Y-Cable: Displays only circuits that are protected by a transponder or muxponder card Y-cable protection group.

Slot

Filters circuits based on the source or destination slot.

Port

Filters circuits based on the source or destination port.

Type

Filters circuits based on their type. Valid entries are:

  • Any: Type is not used to filter circuits.

  • STS: Displays only specific synchronous transport signal (STS) circuits.

  • VT: (ONS 15310-CL, ONS 15327, and ONS 15454 only) Displays only virtual tributary (VT) circuits.

  • VT Tunnel: Displays only VT tunnels.

  • VT Aggregation Point: Displays only VT aggregation points.

  • STS-V: (ONS 15310-CL and ONS 15454 only) Displays only STS virtual concatenated (VCAT) circuits.

  • VT-V: (ONS 15310-CL and ONS 15454 only) Displays only VT VCAT circuits.

  • OCHNC: Displays only OCHNCs.

Size

Filters circuits based on size. Circuit size depends on the source and destination card/port. The sizes you can use to filter circuits include:

  • VT1.5

  • STS-1, STS3c, STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-36c, STS-48c, STS-192c

  • 10 Gb/s FEC, 10 Gb/s No FEC

  • Multi-rate

  • 2.5 Gb/s FEC (forward error correction), 2.5 Gb/s No FEC

  • Equipment non-specific

The check boxes shown depend on the Type field entry. If you chose Any, all sizes are available. If you chose VT or VT-V, only VT1.5 is available. If you chose STS, only STS sizes are available, and if you chose VT Tunnel or VT Aggregation Point, only STS-1 is available. If you chose STS-V, then STS-1, STS-3c, and STS-12c are available. If you chose OCHNC as the circuit type, 2.5 Gb/s FEC, multi-rate, Equipped non-specific, 2.5 Gb/s No FEC, 10 Gb/s FEC, and 10 Gb/s No FEC are available.
