Circuit Protection Types (continued)

 

 

 

Protection Type

 

Description

 

 

 

Protected

 

The circuit is protected by diverse SONET topologies, for example a BLSR and a

 

 

path protection, or a path protection and 1+1.

 

 

 

Unknown

 

A circuit has a source and destination on different nodes and communication is

 

 

down between the nodes. This protection type appears if not all circuit components

 

 

are known.

 

 

 

Unprot (black)

 

A circuit with a source and destination on different nodes is not protected.

 

 

 

Unprot (red)

 

A circuit created as a fully protected circuit is no longer protected due to a system

 

 

change, such as removal of a BLSR or 1+1 protection group.

 

 

 

Path Protection

 

The circuit is protected by a path protection.

 

 

 

7.2.5 Circuit Information in the Edit Circuit Window

You can edit a selected circuit using the Edit button on the Circuits window. The tabs that appear depend on the circuit chosen:

•General—Displays general circuit information and allows you to edit the circuit name.

•Drops—Allows you to add a drop to a unidirectional circuit. For more information, see the “7.5 Multiple Destinations for Unidirectional Circuits” section on page 7-13.

•UPSR Selectors—Allows you to change UPSR selectors. For more information, see the “7.6 Path Protection Circuits” section on page 7-13.

•UPSR Switch Counts—Allows you to change path protection switch paths. For more information, see the “7.6 Path Protection Circuits” section on page 7-13.

•State—Allows you to edit cross-connect service states.

•Merge—Allows you to merge aligned circuits. For more information, see the “7.14 Merged Circuits” section on page 7-26.

Using the Export command from the File menu, you can export data from the UPSR Selectors,

UPSR Switch Counts, State, and Merge tabs in HTML, comma-separated values (CSV), or tab-separated values (TSV) format.

The Show Detailed Map checkbox in the Edit Circuit window updates the graphical view of the circuit to show more detailed routing information, such as:

•Circuit direction (unidirectional or bidirectional)

•The nodes and STSs that the circuit traverses, including slots and port numbers

•The circuit source and destination points

•Open Shortest Path First (OSPF) area IDs

•Link protection (path protection, unprotected, BLSR, 1+1) and bandwidth (OC-N)

For BLSRs, the detailed map shows the number of BLSR fibers and the BLSR ring ID. For path protection configurations, the map shows the active and standby paths from circuit source to destination, and it also shows the working and protect paths. Selectors appear as pentagons on the detailed circuit map.

Alarms and states can also be viewed on the circuit map, including:

•Alarm states of nodes on the circuit route

ONS 15600 specifications

Cisco Systems ONS 15600 is a highly versatile optical networking platform designed to meet the demands of modern telecommunications and data services. This multiservice edge platform supports various transmission mediums and offers a wide array of features that enable efficient data transport. Ideal for service providers and large enterprises, the ONS 15600 is engineered to provide scalable and reliable optical transport solutions.

One of the notable features of the ONS 15600 is its capability to support multiple protocols, including SONET/SDH, Ethernet, OTN, and legacy TDM services. This flexibility allows users to tailor their networks according to specific service requirements while ensuring interoperability with existing infrastructure. The platform is designed to facilitate seamless service migration, accommodating both legacy and next-generation services.

The modular architecture of the ONS 15600 enhances its scalability. It allows for easy expansion by incorporating additional line cards or interface modules without requiring significant downtime. This modularity ensures that service providers can evolve their networks over time, responding to increasing bandwidth demands and new service offerings with ease.

Incorporating advanced technologies, the ONS 15600 employs Dense Wavelength Division Multiplexing (DWDM), significantly increasing the capacity of fiber networks by allowing multiple signals to be transmitted simultaneously over a single optical fiber. This capability helps to optimize fiber utilization and reduce operational costs. In addition, the platform supports Optical Transport Network (OTN) for improved error detection and correction, contributing to higher reliability and performance.

Another key characteristic of the ONS 15600 is its robust management capabilities. The platform can be managed through Cisco's Optical Networking Manager (ONM), providing a centralized interface for network configuration, monitoring, and troubleshooting. This enhances operational efficiency and minimizes downtime, allowing service providers to focus on delivering quality services to their customers.

The ONS 15600 also prioritizes security, offering various features like encryption and access control to safeguard sensitive data during transmission. With its combination of scalability, flexibility, and security, the Cisco ONS 15600 stands out as a reliable choice for organizations looking to enhance their optical networking capabilities while meeting the evolving demands of the digital landscape. Its commitment to quality and performance makes it a cornerstone of modern optical networks.
