Definition

 

 

 

SES-PFE

 

Far-End STS Path Severely Errored Seconds (SES-PFE) is a count of the seconds

 

 

when K (2400) or more STS path BIP errors were detected. An AIS-P defect (or a

 

 

lower-layer, traffic-related, far-end defect) or an LOP-P defect can also cause an

 

 

SES-PFE.

 

 

 

SES-S

 

Section Severely Errored Seconds (SES-S) is a count of the seconds when K (see

 

 

Telcordia GR-253-CORE for value) or more section-layer BIP errors were detected

 

 

or an SEF or LOS defect was present.

 

 

 

UAS-L

 

Line Unavailable Seconds (UAS-L) is a count of the seconds when the line is

 

 

unavailable. A line becomes unavailable when ten consecutive seconds occur that

 

 

qualify as SES-Ls, and it continues to be unavailable until ten consecutive seconds

 

 

occur that do not qualify as SES-Ls.

 

 

 

UAS-LFE

 

Far-End Line Unavailable Seconds (UAS-LFE) is a count of the seconds when the

 

 

line is unavailable at the far end. A line becomes unavailable at the onset of ten

 

 

consecutive seconds that qualify as SES-LFEs, and continues to be unavailable until

 

 

the onset of ten consecutive seconds occurs that do not qualify as SES-LFEs.

 

 

 

UAS-P

 

Near-End STS Path Unavailable Seconds (UAS-P) is a count of the seconds when the

 

 

STS path was unavailable. An STS path becomes unavailable when ten consecutive

 

 

seconds occur that qualify as SES-Ps, and continues to be unavailable until ten

 

 

consecutive seconds occur that do not qualify as SES-Ps.

 

 

 

UAS-PFE

 

Far-End STS Path Unavailable Seconds (UAS-PFE) is a count of the seconds when

 

 

the STS path was unavailable. An STS path becomes unavailable when ten

 

 

consecutive seconds occur that qualify as SES-PFEs, and continues to be unavailable

 

 

until ten consecutive seconds occur that do not qualify as SES-PFEs.

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.
