Chapter 2 Alarm Troubleshooting

2.7.245 UNEQ-P

Step 5 If the Type column does not contain VTT, there are no VT tunnels connected with the alarm. Go to Step 7.

Step 6 If the Type column does contain VTT, attempt to delete these rows by completing the following steps:

Note The node does not allow you to delete a valid VT tunnel or one with a valid VT circuit inside.

a.Click the VT tunnel circuit row to highlight it. Complete the “Delete a Circuit” procedure on page 2-155.

b.If an error message dialog box appears, the VT tunnel is valid and not the cause of the alarm.

c.If any other columns contain VTT, repeat Step 6.

Step 7 If all ONS 15310-CL or ONS 15310-MA nodes in the ring appear in the CTC network view, determine whether the circuits are complete by completing the following steps:

a.Click the Circuits tab.

b.Verify that PARTIAL is not listed in the Status column of any circuits.

Step 8 If you find circuits listed as incomplete, use an optical test set to verify that these circuits are not working circuits that continue to pass traffic. For specific procedures to use the test set equipment, consult the manufacturer.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15310-CL or ONS 15310-MA.

Step 9 If the incomplete circuits are not needed or are not passing traffic, delete the incomplete circuits.

Complete the “Delete a Circuit” procedure on page 2-155.

Step 10 Recreate the circuit with the correct circuit size. Refer to the “Create Circuits” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Step 11 Log back in and verify that all circuits terminating in the reporting port are active by completing the following steps:

a.Click the Circuits tab.

b.Verify that the Status column lists all circuits as active.

Step 12 If the alarm does not clear, clean the far-end optical fiber according to site practice. If no site practice exists, complete the procedure in the “Maintain the Node” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified could result in hazardous radiation exposure. Statement 1057

ONS 15310-CL, ONS 15310-MA specifications

Cisco Systems has long been a leader in networking and telecommunications technology, and among its impressive lineup of products, the Cisco ONS 15310 series stands out as an essential solution for optical networking. This series includes models such as the ONS 15310-MA, ONS 15310-CL, and ONS 15310-CA, each designed to meet the diverse needs of service providers and enterprises seeking to enhance their optical transport networks.

The Cisco ONS 15310-MA is an advanced multi-service platform designed for metropolitan area networks. It facilitates the seamless transport of data, voice, and video over optical networks. One of its main features is its ability to support a variety of interfaces, including Ethernet, SONET/SDH, and Wavelength Division Multiplexing (WDM), allowing users to integrate multiple services into a single platform. Additionally, the ONS 15310-MA supports advanced traffic management and Quality of Service (QoS) features to prioritize critical applications and ensure consistent performance.

The ONS 15310-CL variant is tailored for more specific applications, providing enhanced capabilities aimed at delivering carrier-grade services. It features a robust architecture that accommodates high-capacity traffic without compromising reliability. This model emphasizes low power consumption and a compact design, making it suitable for deployment in space-constrained environments. The ONS 15310-CL also supports a wide range of optical interfaces, making it highly flexible for various network configurations.

In terms of technologies, the Cisco ONS 15310 series leverages Optical Transport Network (OTN) capabilities, providing high efficiency and greater bandwidth utilization. OTN technology enables efficient error correction and adds resilience to the network through its built-in protection mechanisms. Furthermore, the series supports seamless integration with existing IP/MPLS networks, creating a cohesive infrastructure as organizations evolve their networking requirements.

One of the defining characteristics of the ONS 15310 series is its focus on scalability. Network operators can start with a modest deployment and gradually expand capacity as demand grows. This adaptability is complemented by Cisco's comprehensive management and monitoring tools, providing operators with real-time insights into network performance and facilitating proactive management.

In conclusion, the Cisco ONS 15310-MA and ONS 15310-CL models represent sophisticated solutions for modern optical networks. With their versatile features, advanced technologies, and robust design, they empower service providers and enterprises to build resilient, high-capacity networks that meet the demands of today’s data-driven world.
