Push-Button

 

Function

 

 

 

ACO

 

Extinguishes external audible (environmental) alarms. When this button

 

 

is activated, the amber-colored ACO LED turns on.

 

 

 

LAMP TEST

 

Verifies that all the LEDs in the shelf are functioning properly. When

 

 

this button is activated, all of the front-panel LEDs in the shelf turn on

 

 

temporarily to verify operation.

 

 

 

RESET

 

Activates a soft reset of all of the main processor memory on the card.

 

 

Note The RESET button is recessed to prevent accidental activation.

 

 

 

2.3 SSXC Card

Note For hardware specifications, see the “A.2.2 SSXC Specifications” section on page A-6.

The SSXC is the central element for ONS 15600 switching. The SSXC card establishes connections and performs time division switching (TDS) at STS-1 and STS-Nc levels between ONS 15600 traffic cards.

The SSXC card works with the TSC card to maintain connections and set up cross-connects within the ONS 15600. You establish cross-connect and provisioning information using CTC or TL1. The TSC card stores the proper internal cross-connect information and relays the setup information to the SSXC card.

2.3.1 SSXC Switch Matrix

The switch matrix on each SSXC card consists of 6,144 bidirectional STS-1 ports, with a maximum of 6,144 bidirectional STS-1 cross-connections. When creating bidirectional STS-1 cross-connects, each bidirectional cross-connect uses two STS-1 ports, with the result that the SSXC card supports 3,072 bidirectional STS-1 cross-connects. Any STS-1 on any port can be connected to any other port, meaning that the STS cross-connections are nonblocking. Nonblocking connections allow network operators to connect any STS-1, STS-3, STS-12, STS-24, STS-48, or STS-192 payload that is received on an OC-48 or OC-192 interface (or additionally any STS-6 and/or STS-9 payload that is received on an ASAP interface) to any other interface capable of supporting the bandwidth.

The SSXC card has 128 input ports and 128 output ports capable of STS-48. An STS-1 on any of the input ports can be mapped to an STS-1 output port, thus providing full STS-1 time slot assignments (TSAs).

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.
