Network management 53

Call tracking is another feature that is not specifically related to QoS monitoring or fault monitoring, but that is important to solution manageability. With this feature, you can:

track calls that fit defined profiles and collect data for later trend analysis

monitor individual extensions in real time

have alarm notifications sent to pagers or workstations for calls that fit specified profiles

Communication Server 1000 Telephony Manager can perform some alarm-management functions and is a trap receiver for the voice products it supports. It polls call servers, through SNMP, for additional alarms that are not sent as traps. Alarms can be received from the CS 1000. Communication Server 1000 Telephony Manager can display fault information locally and also send the traps on to ENMS, Vivinet Manager, or other management platforms.

Monitoring and reporting with NetiQ Vivinet Assessor, Vivinet AppManager, and Vivinet Diagnostics

Vivinet Assessor is a Network Health Check and diagnostics tool. The software also has a number of features for the ongoing monitoring and reporting of issues. You can install Performance Endpoint agents on laptops that have WLAN interfaces, to monitor the performance and quality of the WLAN. Send this data to the Vivinet Manager for reporting and analysis. You can configure the agents with a schedule for generating VoIP traffic to run spot checks on the ability of the network to support VoIP at required quality levels.

Vivinet AppManager is a product that can be purchased separately and used in conjunction with Vivinet Diagnostics to provide detailed service-level monitoring, reporting, and troubleshooting in a diverse network environment.

For the CS 1000, Vivnet AppManager provides information about the percentage of devices available versus unavailable, health of interfaces, Voice Call Quality and QoS for Signaling Server, and Voice Gateway Media Cards. AppManager also provides summary analysis for data loss, jitter, latency, and R-Value.

Vivinet Diagnostics is a product that can be purchased separately and used in conjunction with Vivinet AppManager. After Vivinet AppManager receives a call-quality alert from a Nortel voice system such as a CS 1000 or BCM for a call in progress, AppManager generates an alert.
