Note Transaction Language One (TL1) can be used to provision the required SONET point-to-point circuits instead of CTC.

Connecting the ML-Series Cards with Point-to-Point STS Circuits

You connect the ML-Series cards in an RPR through point-to-point STS circuits. These circuits use the SONET network and are provisioned using CTC in the normal manner for provisioning optical circuits.

Configuring CTC Circuits for RPR

These are the guidelines for configuring the CTC circuits required by RPR:

•Leave all CTC Circuit Creation Wizard options at their default settings, except Fully Protected Path in the Circuit Routing Preferences dialog box. Fully Protected Path provides SONET protection and should be unchecked. RPR normally provides the Layer 2 protection for SPR circuits.

•Check Using Required Nodes and Spans to route automatically in the Circuit Routing Preferences dialog box. If the source and destination nodes are adjacent on the ring, exclude all nodes except the source and destination in the Circuit Routing Preferences dialog box. This forces the circuit to be routed directly between source and destination and preserves STS circuits, which would be consumed if the circuit routed through other nodes in the ring. If there is a node or nodes that do not contain an ML-Series card between the two nodes containing ML-Series cards, include this node or nodes in the included nodes area in the Circuit Routing Preference dialog box, along with the source and destination nodes.

•Keep in mind that ML-Series card STS circuits do not support unrelated circuit creation options, such as the following check box titles in CTC, unidirectional traffic, creating cross-connects only (TL1-like), interdomain (unified control plane [UCP]), protected drops, subnetwork connection protection (SCNP), or path protectionpath selectors.

•A best practice is to configure SONET circuits in an east-to-west or west-to-east configuration, from Port 0 (east) to Port 1 (west) or Port 1 (east) to Port 0 (west), around the SONET ring. Do not configure Port 0 to Port 0 or Port 1 to Port 1. The east-to-west or west-to-east setup is also required in order for the CTM network management software to recognize the ML-Series configuration as an SPR.

Detailed CTC circuit procedures are available in the “Create Circuits and VT Tunnels” chapter of the Cisco ONS 15454 Procedure Guide.

15310-CL, 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.
