Chapter 10 Alarm Monitoring and Management

External Alarms and Controls

10.5.1 Alarms Suppressed for Maintenance

When you place a port in locked, maintenance administrative state, this raises the alarm suppressed for maintenance (AS-MT) condition in the Conditions and History windows1 and causes subsequently raised alarms for that port to be suppressed.

While the facility is in the locked, maintenance state, any alarms or conditions that are raised and suppressed on it (for example, a transmit failure [TRMT] alarm) are reported in the Conditions window and show their normal severity in the Sev column. The suppressed alarms are not shown in the Alarms and History windows. (These windows only show AS-MT). When you place the port back into Automatic In Service administrative state, the AS-MT condition is resolved in all three windows. Suppressed alarms remain raised in the Conditions window until they are cleared.

10.5.2 Alarms Suppressed by User Command

In the Provisioning > Alarm Profiles > Alarm Behavior tabs, the ONS 15310-MA SDH have an alarm suppression option that clears raised alarm messages for the node, chassis, one or more slots (cards), or one or more ports. Using this option raises the alarms suppressed by user command, or AS-CMD condition. The AS-CMD condition, like the AS-MT condition, appears in the Conditions, and History1 windows. Suppressed conditions (including alarms) appear only in the Conditions window—showing their normal severity in the Sev column. When the Suppress Alarms check box is unchecked, the AS-CMD condition is cleared from all three windows.

A suppression command applied at a higher level does not supersede a command applied at a lower level. For example, applying a node-level alarm suppression command makes all raised alarms for the node appear to be cleared, but it does not cancel out card-level or port-level suppression. Each of these conditions can exist independently and must be cleared independently.

Caution Use alarm suppression with caution. If multiple CTC or TL1 sessions are open, suppressing the alarms in one session suppresses the alarms in all other open sessions.

10.6 External Alarms and Controls

External alarm physical connections are made with the ONS 15310-MA SDH ALARM port. However, the alarms are provisioned using the 15310E-CTX-K9 card view for external sensors such as an open door and flood sensors, temperature sensors, and other environmental conditions. External control outputs on the 15310E-CTX-K9 cards allow you to drive external visual or audible devices such as bells and lights. They can control other devices such as generators, heaters, and fans.

Provision external alarms in the 15310E-CTX-K9 card view Provisioning > External Alarms tab and provision controls in the 15310E-CTX-K9 card view Provisioning > External Controls tab. Up to 32 alarm contact inputs and 8 alarm contact outputs are available with the 15310E-CTX-K9 cards.

10.6.1 External Alarm Input

You can provision each alarm input separately. Provisionable characteristics of external alarm inputs include:

1.AS-MT can be seen in the Alarms window as well if you have set the Filter dialog box to show NA severity events.

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.
