Button/Check box/Tool

Action

 

 

 

Filter button

 

Allows you to change the display in the Alarms window to show only

 

 

alarms that meet a certain severity level, occur in a specified time frame,

 

 

and/or reflect specific conditions. For example, you can set the filter so that

 

 

only Critical alarms are displayed in the window.

 

 

If you enable the Filter feature by clicking the Filter tool in one CTC view,

 

 

such as node view, it is enabled in the others as well (card view and network

 

 

view).

 

 

Synchronize button

Updates the alarm display. Although CTC displays alarms in real time, the

 

 

Synchronize button allows you to verify the alarm display. This is

 

 

particularly useful during provisioning or troubleshooting.

 

 

Delete Cleared Alarms

Deletes, from the view, alarms that have been cleared.

button

 

 

 

 

AutoDelete Cleared

If checked, CTC automatically deletes cleared alarms.

Filter tool

 

Enables or disables alarm filtering in the card, node, or network view. When

 

 

enabled or disabled, this state applies to other views for that node and for

 

 

all other nodes in the network. For example, if the Filter tool is enabled in

 

 

the node (default login) view Alarms window, the network view Alarms

 

 

window and card view Alarms window also show the tool enabled. All other

 

 

nodes in the network also show the tool enabled.

 

 

 

10.2.3 Filtering Alarms

The alarm display can be filtered to prevent display of alarms with certain severities or alarms that occurred between certain dates and times. You can set the filtering parameters by clicking the Filter button at the bottom-left of the Alarms window. You can turn the filter on or off by clicking the Filter tool at the bottom-right of the window. CTC retains your filter activation setting. For example, if you turn the filter on and then log out, CTC keeps the filter active the next time you log in.

10.2.4 Viewing Alarm-Affected Circuits

To view which ONS 15310-MA SDH circuits are affected by a specific alarm, right-click an alarm in the Alarm window. A shortcut menu appears, as shown in Figure 10-1. (This figure illustrates the

ONS 15310-MA SDH Select Affected Circuits shortcut menu.) When you select the Select Affected Circuits option, the Circuits window opens to show the circuits that are affected by the alarm.

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.
