Chapter 2 Alarm Troubleshooting

2.7.35 BLSROSYNC

Step 3 If the 15310-CL-CTX or CTX2500 card does not reboot successfully, or the alarm has not cleared, call Cisco TAC (1-800-553-2447).

2.7.35 BLSROSYNC

The BLSROSYNC alarm is not used in the ONS 15310 platforms in this release. It is reserved for development.

2.7.36 CARLOSS (CE100T)

Default Severity: Major (MJ), Service-Affecting (SA)

SONET Logical Object: CE100T

The Carrier Loss alarm is raised on CE-Series cards in Mapper mode when the port is In-Service (IS) state and if there is no carrier signal. Circuit need not be present to raise the alarm. In releases prior to 6.01 the Carrier Loss alarm is raised on CE-100T-8 cards in Mapper mode when there is a circuit failure due to link integrity. It does not get raised when a user simply puts the port in the In-Service and Normal (IS-NR) service state.

Step 1 Verify that the fiber cable is properly connected and attached to the correct port. For more information about fiber connections and terminations, refer to the “Install Hardware” chapter in the

Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

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

Step 2 If the fiber cable is correctly connected and attached, verify that the cable connects the card to another Ethernet device.

Step 3 Verify that the attached transmitting Ethernet device is operational. If not, troubleshoot the device.

Step 4 Verify that optical receive levels are within the normal range. The correct specifications are listed in the “Install Hardware” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide.

Step 5 If the alarm does not clear, use an Ethernet test set to determine whether a valid signal is coming into the Ethernet port. For specific procedures to use the test set equipment, consult the manufacturer.

Step 6 If a valid Ethernet signal is not present and the transmitting device is operational, replace the fiber cable connecting the transmitting device to the Ethernet port. To do this, refer to the “Install Hardware” chapter in the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide for procedures.

Step 7 If the alarm does not clear, and link autonegotiation is enabled on the port but the autonegotiation process fails, the card turns off its transmitter laser and reports a CARLOSS alarm. If link autonegotiation has been enabled for the port, determine whether there are conditions that could cause autonegotiation to fail by completing the following steps:

a.Confirm that the attached Ethernet device has autonegotiation enabled and is configured for compatibility with the asymmetric flow control on the card.

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.
