2.6 E1_21_E3_DS3_3 and E1_63_E3_DS3_3 Cards

Note For hardware specifications, see the “A.2.5 E1_21_E3_DS3_3 and E1_63_E3_DS3_3 Cards” section on page A-7.

The ONS 15310-MA SDH E1_21_E3_DS3_3 and E1_63_E3_DS3_3 cards provide 21 and 63 ITU-Compliant G.703 E1 ports, respectively, as well as three E3/DS3 ports. Each E1 port operates at 2.048 Mbps. Each E3/DS3 port operates at 34.368 Mbps/44.736 Mbps over a single 75-ohm 728 A or equivalent coaxial span. These cards can operate as a working or protect card in 1:1 protection schemes.

In addition, the E1_21_E3_DS3_3 card provides retiming, so that any outgoing E1 signal can be retimed to eliminate accumulated jitter and wander at the point of egress from a synchronous network. Any incoming E1 signal from the transport element can also be used as a timing source.

The E1_21_E3_DS3_3 and E1_63_E3_DS3_3 cards can be installed in Slots 1, 2, 5, and 6. Card installed in Slots 1 and 2 correspond with the electrical interface assembly (EIA) installed on Side A at the rear of the shelf assembly, and cards in Slots 5 and 6 correspond with the EIA installed on Side B.

See the “3.2.1 1:1 Electrical Card Protection” section on page 3-2for information about electrical card protection and supported shelf configurations.

15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
