4.6 CTC Card Reset

You can reset the ONS 15600 cards by using the hard-reset or soft-reset commands in CTC, or by physically reseating a card (card pull). From the node view, select a card and right-click to open a menu with the hard-reset and soft-reset commands. Soft resets do not impact traffic, however hard resets are service-affecting. A card must be in the Out-of-Service and Management, Maintenance (OOS-MA,MT) service state before you can perform a hard reset.

A soft reset on the TSC reboots the TSC and reloads the operating system and the application software. You can apply a CTC soft reset to either an active or standby TSC without affecting traffic. A CTC hard reset temporarily removes power from the TSC and clears all buffer memory.You should only perform a hard reset (or a card pull) on a standby TSC. If you need to perform a CTC hard reset or card pull on an active TSC, put the TSC into standby mode first by performing a soft reset.

A soft reset on an optical card with an active port in a 1+1 protection group will result in a loss of all DCC traffic terminated or tunneled on the active port for the duration of the reset time. A soft reset of an optical card with a standby port in a 1+1 protection group will not affect DCC traffic. A CTC hard reset of an optical card causes a switch to the protect card.

4.7 TSC Card Database

Each TSC card hosts a separate database; therefore, the protect card’s database is available if the database on the working TSC fails. After a database change, there might be a 30-second interval before the TSC starts writing the data to the Flash drive. If you reset the active TSC immediately after a database change, the change could be lost.

You can also store a backup version of the database on the workstation running CTC. This operation should be part of a regular ONS 15600 maintenance program at approximately weekly intervals and should also be completed when preparing an ONS 15600 for a software upgrade or a pending natural disaster, such as a flood.

Note The Internet Inter-ORB Protocol (IIOP) port is not backed up and restored.

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.
