CE-MR-6 Ethernet Card

CE-MR-6 Pool Allocation

Note CE-MR Pool allocation can be set for ONS 15310-MA only and can be provisioned only when the card is in automatic provisioning mode.

CE-MR-6 has the following characteristics:

One pool can support only one circuit (from any front port), and must be a STS-48c circuit only. Two pools of 24 STSs each can be independently allocated.

•Ports 1-4 assigned to pool 1; ports 5-6 to pool 2.

•Each pool can support only one circuit type at a time. The circuit types are:

–1 STS-24c

–Up to 2 STS-12cs

–Up to 2 STS-9cs

–Up to 4 STS-6cs

–Up to 4 CCATs/ VCATs made up of STS-1s

–Up to 4 CCATs/VCATs made up of STS-3cs

–Number of members available for VCAT is subject to the total limit of 24 STSs in pool 1 and 23 STSs (or 21 STSs in case of STS-3C/VC4) in pool 2 (per VCG limit 21 STSs)

•In addition, Pool1 can also support low order circuits (but not pool2)

•VT1.5 based VCATs are subject to a total limit of 144 VT1.5s

(For Release 9.0, per VCG limit is 64. For Release 9.1 and later, per VCG limit is 63.)

•The 1 pool versus 2 pool operation is decided dynamically by the first circuit provisioned.

•If two pool exists, then the mode of each pool is decided dynamically by the circuit types provisioned.

CE-MR-6 VCAT Characteristics

The CE-MR-6 card has hardware-based support for the ITU-T G.7042 standard LCAS. This allows the user to dynamically resize a high order or low order VCAT circuit through CTC or TL1 without affecting other members of the virtual concatenation group (VCG) (errorless).

The ONS 15310 ML100X-8 card has a software-based LCAS (SW-LCAS) scheme. Software LCAS is supported on CE-MR-6 cards for interoperation with these cards.

The SW-LCAS is not supported on CE-MR-6 cards for interoperation with the CE-100T-8 and ML-MR-10 cards.

Note The CE-MR-6 card does not support interoperation between the LCAS and non-LCAS circuits.

The CE-MR-6 card allows independent routing and protection preferences for each member of a VCAT circuit. Alarms are supported on a per-member as well as per-VCG basis.

Note A differential delay of 135 ms is supported for high order circuits and low order circuits.

ONS 15310-CL, ONS 15310-MA, Cisco 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.
