Purpose

This task provisions the Open System Interconnection (OSI) routing mode.

 

Complete this task when the ONS 15454 is connected to networks with

 

third party network elements (NEs) that use the OSI protocol stack for data

 

communications network (DCN) communication.

Tools/Equipment

None

Prerequisite Procedures

Required/As Needed

As needed

Onsite/Remote

Security Level

Provisioning or higher

Do not complete this task until you confirm the role of the node within the network. It will be either an ES, IS Level 1, or IS Level 1/Level 2. This decision must be carefully considered. For additional information about OSI provisioning, refer to the “Management Network Connectivity” chapter of the Cisco ONS 15454 Reference Manual.

Link State Protocol (LSP) buffers must be the same at all NEs within the network, or loss of visibility might occur. Do not modify the LSP buffers unless you confirm that all NEs within the OSI have the same buffer size.

LSP buffer sizes cannot be greater than the LAP-D maximum transmission unit (MTU) size within the OSI area.

For ONS 15454 nodes, three virtual routers can be provisioned. The node primary NSAP address is also the Router 1 primary manual area address. To edit the primary NSAP, you must edit the Router 1 primary manual area address. After you enable Router 1 on the Routers subtab, the Change Primary Area Address button is available to edit the address.

Step 1 Complete the DLP-A60 Log into CTC, page 17-69at the node where you want to provision the OSI routing mode. If you are already logged in, continue with Step 2.

Step 2 In node view, click the Provisioning > OSI > Main Setup tabs.

Step 3 Choose a routing mode:

•End System—The ONS 15454 performs OSI end system (ES) functions and relies upon an intermediate system (IS) for communication with nodes that reside within its OSI area.

Note The End System routing mode is not available if more than one virtual router is enabled.

•Intermediate System Level 1—The ONS 15454 performs OSI IS functions. It communicates with IS and ES nodes that reside within its OSI area. It depends upon an IS L1/L2 node to communicate with IS and ES nodes that reside outside its OSI area.

ONS 15454 specifications

Cisco Systems ONS 15454 is a versatile optical networking platform designed to enable service providers and enterprises to deploy and manage robust optical networks efficiently. The ONS 15454 serves as a cornerstone in the evolution of transport networks, featuring various technologies that meet the increasing demand for bandwidth and service quality.

One of the standout features of the ONS 15454 is its support for multiple service types, including TDM, Ethernet, and Wavelength Division Multiplexing (WDM). This capability allows service providers to maximize network resources while delivering a wide range of services, from traditional voice to high-speed data and video.

The ONS 15454 leverages Dense Wavelength Division Multiplexing (DWDM) technology, enabling the transmission of multiple data streams over a single optical fiber. This effectively expands the network's capacity without the need for additional infrastructure, a crucial benefit in today's ever-growing data landscape. The system supports a variety of transponder modules, allowing for flexible scaling and seamless upgrades as bandwidth requirements increase.

Scalability is another key characteristic of the ONS 15454. With its modular architecture, it accommodates a range of interfaces and line cards, making it easier to tailor deployments to specific customer needs. This modularity not only facilitates upgrades but also simplifies maintenance, minimizing downtime and operational costs.

The platform also features advanced management capabilities through Cisco's Optical Network Management system. This allows for real-time monitoring, provisioning, and troubleshooting, ensuring network reliability and performance. The intuitive interface and comprehensive reporting tools enable operators to gain insights into network operations, improving decision-making processes.

Furthermore, the ONS 15454 is built to support optical layer protection features, enhancing network resilience. Technologies such as Automatic Protection Switching (APS) and Optical Supervisory Channel (OSC) ensure that connectivity is maintained even in the event of a failure, crucial for mission-critical applications.

In conclusion, the Cisco ONS 15454 is a powerful optical networking solution that combines flexibility, scalability, and advanced management features. Its support for various services and technologies positions it as an essential asset for organizations looking to build a future-proof network capable of handling increasing data traffic while maintaining high service standards.
