1.4.1 FEAC Send Code

Figure 1-1 Accessing FEAC Functions on the DS3 ports of WBE-28/WBE-84 Cards

The "far end" in FEAC refers to the equipment connected to the WBE card and not to the far end of a circuit. In Figure 1-2, if a WBE-28/WBE-84 DS3 (near-end) port is configured to send a line loop code, the code will be sent to the connected test set, not the WBE-28/WBE-84 DS3 (far-end) port. FEAC functions will be available only when the DS3 port is configured in CBIT Framing.

1.4.1 FEAC Send Code

The Send Code column on the WBE-28/WBE-84 cards Maintenance tab only applies to OOS-MA,MT ports configured for CBIT framing. The column lets a user select No Code (the default) or line loop code. Selecting line loop code inserts a line loop activate FEAC in the CBIT overhead transmitting to the connected facility. This code initiates a loopback from the facility to the ONS 15310-MA. Selecting No Code sends a line-loop-deactivate FEAC code to the connected equipment, which will remove the loopback.

ONS 15310-CL, 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.
