Chapter 17 CE-Series Ethernet Cards

CE-MR-6 Ethernet Card

This circuit is supported only on CCAT circuit sizes of STS-48c, STS-24c, STS-12c, STS-9c, STS-6c, STS-3c, and STS-1 (ANSI) or VC3, VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, and VC4-16c (ETSI). The creation of Ethernet drop and continue (unidirectional) circuits is supported on protected (path protected/SNCP and 1+1 protection) schemes and unprotected circuits with multiple drop points.

Note The Ethernet drop and continue feature is supported on all cross-connect cards except XC and XCVT.

The ONS 15310 configuration determines the maximum drop points supported—multiple drops on ports of the same card or different cards in the chassis. Figure 17-10shows unidirectional drop from POS0 port on CE-MR-6 A to ports POS0, POS1, POS2, POS3 of the CE-MR-6 B.

The Ethernet drop and continue feature supports unidirectional link integrity and performance management.

Alarms are monitored in the forward direction for the Ethernet drop and continue circuits and suppressed in the reverse direction, that is, STS alarms will not be detected at the source port. These unidirectional circuits are configured through CTC and TL1. To create an Ethernet drop and continue circuit, see “Chapter 6, Create Circuits and VT Tunnels” of the Cisco ONS 15310-CL and Cisco ONS 15310-MA Procedure Guide. For TL1 provisioning commands, refer to the Cisco ONS SONET TL1 Command Guide. For information on Alarms, see “Chapter 2, Alarm Troubleshooting” of the Cisco ONS 15310-CL and Cisco ONS 15310-MA Troubleshooting Guide.

Administrative and Service States with Soak Time for Ethernet and SONET Ports

The CE-MR-6 card can be managed by TL1, SNMP, CTC or CTM. The card supports the administrative and service states for the Ethernet ports and the SONET circuit. For more information about card and circuit service states, refer to the “Administrative and Service States” appendix in the

Cisco ONS 15310-CL and Cisco ONS 15310-MA Reference Manual.

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.
