Chapter 11 Alarm Monitoring and Management

11.2.1 Alarm Window

Software Releases 7.0 and later have TL1 port-based alarm numbering that identifies an alarmed synchronous transport signal (STS) by its STS on a port rather than the STS on the optical card. The numbering is present in the STS alarm TL1 AID. The numbering scheme is described in Table 11-3.

Table 11-3 TL1 Port-Based Alarm Numbering Scheme

MON Object

 

(Optical)

Syntax and Examples

 

 

OC3/12/48/192

Syntax: STS-<Slot>-<Pim>-<Ppm>-<Port>-<STS>

STS

Ranges: STS-{1-4,11-14}-{1-4}-{1-4}-{1-n1}-{1-n2}

 

Example: STS-1-1-1-1-6

 

 

1.Port number range varies by card type with a maximum of four.

2.Maximum STS number depends on the rate and size of the STS.

11.2.1Alarm Window

Table 11-4shows the actions you can perform in the Alarms window.

Button

 

Action

 

 

 

Filter

 

Allows you to change the display on the Alarms window to show only

 

 

alarms that meet a certain severity level, occur in a specified time frame,

 

 

and/or reflect specific conditions. For example, you can set the filter so that

 

 

only Critical alarms appear on the window.

 

 

If you enable the Filter feature by clicking the Filter icon button in one CTC

 

 

view, such as node view, it is enabled in the others as well (card view and

 

 

network view).

 

 

 

Synchronize

 

Updates the alarm display. Although CTC displays alarms in real time, the

 

 

Synchronize button verifies that CTC and the ONS 15600 agree on current

 

 

alarms. This is particularly useful during provisioning or troubleshooting.

 

 

Delete Cleared Alarms

Deletes alarms that have been cleared.

 

 

AutoDelete Cleared

If checked, CTC automatically deletes cleared alarms.

11.2.2 Alarm-Affected Circuits

You can determine which ONS 15600 circuits are affected by a specific alarm by positioning the cursor over the alarm in the Alarm window and right-clicking. A shortcut menu appears (Figure 11-2).

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.
