Caveats

Optical IO Cards

CSCse08282

When the Active XC is removed, the traffic from the line card might be lost. If the line card is an ASAP card, the lack of traffic will cause a low transition signal density to enter the ASAP line card ASIC on the backplane egress interface. The downstream FPGA on the ASAP 1PIO daughter card will begin detecting B1 errors. These B1 errors will cause unexpected path protection switches. These errors will also be reported as equipment failures.

To avoid this issue ensure that the Active XC is in OOS-MT state before removing it. If this issue does occur, reset the 1PIO ASAP daughter card to clear the errored state. Resetting the ASAP carrier card will also clear the errored state. This issue will be resolved in a future release.

In ASAP card view, the PIM graphic might not update with the correct color after an alarm is cleared. This can occur anytime there is an alarm raised against the PIM or any of its subcomponents (PPM or port). To recover from this state, you must either click the Synchronize button, or change to node view and then back to card view. This issue will be resolved in a future release.

CSCef20813

No graphical representations of LEDs for ASAP ports are displayed in the CTC card view. SD and SF LED representations are also absent from the CTC node view for some legacy OCn cards. There are no plans to resolve this issue.

BLSR Functionality

CSCsd62731

When you create a circuit in IS,AINS state while a BLSR is in the switch state the circuit will not transition from IS/AINS to IS. To avoid this ensure that the BLSR is in a stable state before creating a circuit. This issue will be resolved in a future release.

CSCeh49665

Connections might still exist after circuit deletions on BLSR DRI rings for which the primary node is isolated. For BLSR DRI rings with several types of DRI circuits, if you isolate the primary node by deleting the database, reseat the I/O cards, then delete all BLSR DRI circuits, the SSXCs still show connections. To avoid this issue, do not delete or create BLSR DRI circuits when a node on the BLSR DRI ring is isolated. This issue will not be resolved.

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.
