Chapter 3 Card Protection

ONS 15310-MA SDH Card and Port Protection

Aprotection group is automatically formed, with the E1_21_E3_DS3_3 card operating as the working card, and the E1_63_E3_DS3_3 card operating as the protection card.

Automatic protection groups cannot be created or deleted by users. A protection group is automatically deleted when the protect card is deleted.

3.2.2 .LMSP Optical Port Protection

With two 15310E-CTX-K9 cards installed, four optical ports are available (two on each card). A Linear Multiplex Section Protection group can be created between any two pairs of optical ports with matched port rates.

A protection group can be created using two ports on the same 15310E-CTX-K9 card or between ports on adjacent 15310E-CTX-K9 cards. You can also create a 1+1 protection group on each card for a total of two protection groups. In this case, working and protection ports are provisioned on Slot 3 and working and protection ports are provisioned on Slot 4 (the same card can have both working and protect ports on it).

3.2.3 .15310E-CTX-K9 Card Equipment Protection

The ONS 15310MA supports a single and dual 15310E-CTX-K9 card configurations. In the dual configuration, with a 15310E-CTX-K9 card inserted in Slot 3 and Slot 4, the 15310E-CTX-K9 card is also protected. One of the cards becomes the active card and the other becomes the standby card. Soft resets executed in the dual 15310E-CTX-K9 card configuration as well as in the single 15310E-CTX-K9 card configuration are errorless. Software upgrades in the single and dual configurations are also errorless.

In the dual configuration, there is a switchover from the active 15310E-CTX-K9 card to standby 15310E-CTX-K9 card during the soft reset of the active 15310E-CTX-K9 card. After the soft reset or software upgrade, the old standby 15310E-CTX-K9 card becomes the new active 15310E-CTX-K9 card. The old active 15310E-CTX-K9 card becomes the standby 15310E-CTX-K9 card.

The 15310E-CTX-K9 card is equipment protected in a dual 15310E-CTX-K9 card configuration. Any reset occurring on the active 15310E-CTX-K9 card that is triggered due to failure causes a switchover of the 15310E-CTX-K9 card, causing the old standby card to become the active card.

Note The ONS 15310-MA SDH and the 15310E-CTX-K9 card do not support SNCP switching for VC3

 

 

circuits containing BIP errors. The SF/SD alarm is not raised for VC3 circuits.

 

 

 

 

 

If there are any path protection or 1+1 protected ports configured across the two 15310E-CTX-K9 cards,

 

 

a protection switch will cause the port on the active 15310E-CTX-K9 card to become the active port for

 

 

1+1 or the path protection selector.

 

 

 

Note

Any unprotected port on the 15310E-CTX-K9 card being reset may undergo a traffic loss when the

 

 

15310E-CTX-K9 is reinitialized.

 

 

If protection exists between two optical ports on the same 15310E-CTX-K9 card and if that

 

 

15310E-CTX-K9 card is reset, the traffic might be affected when the 15310E-CTX-K9 card is

 

 

reinitialized.

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.
