B.2 Administrative States

Table B-2

ONS 15600 Secondary States

 

Secondary State

Definition

 

 

 

AINS

 

(Automatic In-Service) The entity is delayed before transitioning to the IS-NR

 

 

service state. The transition to IS-NR depends on correction of conditions, or on a

 

 

soak timer. Alarm reporting is suppressed, but traffic is carried. Raised fault

 

 

conditions, whether or not their alarms are reported, can be retrieved on the CTC

 

 

Conditions tab or by using the TL1 RTRV-COND command.

 

 

 

DSBLD

 

(Disabled) The entity was manually removed from service and does not provide its

 

 

provisioned functions. All services are disrupted; the entity is unable to carry

 

 

traffic.

 

 

 

FLT

 

(Fault) The entity has a raised alarm or condition.

 

 

 

LPBK

 

(Loopback) The entity is in loopback mode.

 

 

 

MEA

 

(Mismatched Equipment) An improper card is installed. For example, an installed

 

 

card is not compatible with the card preprovisioning or the slot. This SST applies

 

 

only to cards.

 

 

 

MT

 

(Maintenance) The entity has been manually removed from service for a

 

 

maintenance activity but still performs its provisioned functions. Alarm reporting

 

 

is suppressed, but traffic is carried. Raised fault conditions, whether or not their

 

 

alarms are reported, can be retrieved on the CTC Conditions tab or by using the

 

 

TL1 RTRV-COND command.

 

 

 

SWDL

 

(Software Download) The card is involved in a software and database download.

 

 

This SST applies only to cards.

 

 

 

UAS

 

(Unassigned) The card is not provisioned in the database. This SST applies only to

 

 

cards.

 

 

 

UEQ

 

(Unequipped) The card is not physically present (that is, an empty slot). This SST

 

 

applies only to cards.

 

 

 

B.2 Administrative States

Administrative states are used to manage service states. Administrative states consist of a PST and an SST. Table B-3lists the administrative states supported by the ONS 15600. See Table B-2for SST definitions.

Note A change in the administrative state of an entity does not change the service state of supporting or supported entities.

Administrative State (PST,SST)

Definition

 

 

 

IS

 

Puts the entity in-service.

 

 

 

IS,AINS

 

Puts the entity in automatic in-service.

 

 

 

OOS,DSBLD

 

Removes the entity from service and disables it.

 

 

 

OOS,MT

 

Removes the entity from service for maintenance.

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.
