Infrastructure Manager operates an interconnect service network and does not use the Subscriber Management and Access Application. Configuration (and provisioning) is provided by the Infrastructure Configuration Application, Fault, Performance and Accounting are provided by the Fault Management, Performance Management, and Accounting Data Applications, respectively. Security Administration is distributed among the other applications and supported by security functions. A Unified Operator and OSS Interface provides friendly and effective access to the FCAPS functions of the Cisco Internet OSS for VoIP: Infrastructure Manager. Troubleshooting and Maintenance functions augment the FCAPS applications to enhance the NOC's ability to sustain high service quality.

Cisco Packet-Voice Infrastructure Configuration Application

The Cisco Packet-Voice Infrastructure Configuration Application provides the service provider with packet-voice network provisioning and configuration for the virtual switch, including the signaling gateway, call agent, gateway, and gatekeeper. The application provides network-wide dialing-plan management and bulk element provisioning to alleviate repetitive activities when multiple elements need the same configuration. The Packet-Voice Infrastructure Configuration Application works from an end-to-end packet-voice network view and provides graphical, drag-and-drop provisioning in addition to flow-through provisioning. Figures 2 and 3 illustrate these features.

Cisco Packet-Voice Fault Management Application

The Cisco Packet-Voice Fault Management Application provides surveillance of Cisco VIA deployments. The rules capability of the application facilitates elimination of duplicates, filtering, and correlation. Permissions may be used to partition the views that operators will see and control the functions that they may execute. The Fault Management Application is shared among Cisco solutions and supports an end-to-end view of the network, showing the impact of non-voice and non-infrastructure applications. The application offers a capability for launching troubleshooting tools and scripts, and can analyze relevant system log messages and produce alarms where appropriate (Figure 4). This results in a richer set of events and alarms than those currently available from Simple Network Management Protocol (SNMP) traps.

Cisco Packet-Voice Performance Management Application

The Cisco Packet-Voice Performance Management Application provides information necessary to monitor the quality of the network relative to usage, throughput, and voice quality, optimizing data collection to minimize the load on the network. The Performance Management Application provides numerous reports, including minutes of use, completed calls, dropped calls, long calls, and trunk use. The Performance Management Application provides threshold capability on any normalized data item and generates events and alarms to the Fault Management Application. Additionally, the application offers selective (hot spot) polling, providing near-real-time data for selected items.


Figure 5
Performance Management


Cisco produces normalized performance data that third-party applications (a Cisco ecosystem partner, a customer-supplied OSS, or another third-party application) can use to generate reports and perform analyses (Figure 5). As needed, Cisco will work with application vendors or with the service provider's application organization to support performance reporting. Cisco operates a joint development program (JDP) that works with strategic partners to produce performance management offerings that manage Cisco VIA networks. Cisco also provides support for some vendors through the Cisco Ecosystem Select program to make similar offerings available.

Accounting Data Application

The Cisco Internet OSS for VoIP: Infrastructure Manager offering does not include a billing OSS. The architecture assumes that the service provider will choose a vendor to provide billing record mediation, bill production, and bill management. Cisco provides call detail records and supports the chosen vendor to accomplish billing for service.

Security Administration

A policy server, Cisco CNS Administrative Policy Engine, that is accessed by the Cisco packet-voice applications provides security on a centralized basis. This provides consistent authentication for logging into a Cisco Packet-Voice Infrastructure Network Management Launch Pad. From this entry-point console and within the various trails that might be navigated, role-based authorization and function access is administered:

  • Administrator

  • Operator

  • Maintenance technician

  • Provisioning technician

  • Operations manager, etc.

Unified Operator Interface

The NOC manager uses Cisco Internet OSS for VoIP: Infrastructure Manager via Launch Pads, a single-system image, user-friendly navigation station. The interface is Web Based—easily integrated with existing graphical user interface (GUI)-based processes that the service provider has in place or needs to implement in the future. This interface presents all solution capabilities to the operator through hierarchical menus (Figure 6).

Operator Interface and GUI


Troubleshooting and Maintenance

The applications in the Cisco Internet OSS for VoIP: Infrastructure Manager give the operator access to tools in the Cisco Packet-Voice Network Maintenance Toolkit—tools that can be used to restore network availability, improve network quality, and investigate network anomalies. This toolkit offers network-element-specific functionality to view graphical network element layouts, override network element configurations, investigate network element performance activity, probe network communication and routing activity, trace calls, and measure QoS. The toolkit also provides Telnet access to let the operator communicate with devices for control through the command-line interface. The Infrastructure Manager includes products to help identify inconsistencies among voice network elements during initial device staging and subsequently when all the devices are assimilated, providing insight into network performance, real-time statistical reporting, and real-time call tracing to troubleshoot voice networks. A nonintrusive packet telephony monitoring and troubleshooting tool captures network packets in real-time, traces calls, analyzes call control protocol packets to help customers quickly and efficiently deploy, monitor, and troubleshoot VoIP services on a data network. All of the protocols in Cisco VIA are supported by the packet telephony monitoring and troubleshooting tool.
