Data Sheet


Cisco Packet Telephony Center
Virtual Switch Version 3.1


Cisco® Packet Telephony Center Virtual Switch (PTC-VS) provides the carrier-class network-management functions, scalability, and reliability required by telephony centers and telecommunications service providers. Cisco PTC-VS features include virtual entity and management concepts, multiuser support, multithreaded programming, and Web-browser-based client access. Refer to Table 1 for a summary of Cisco PTC-VS features and benefits and the Cisco PTC-VS white paper for detailed information.

Product Description

Cisco PTC is a carrier-class service- and network-management system that provisions the business voice services, including the Cisco Voice-over-IP (VoIP) Softswitch, the virtual-packet-voice-switch connection between the public switched telephone network (PSTN) and the VoIP service provider network, the Cisco CallManager Express, and the Cisco PGW Route Server Complex. Cisco PTC as the voice domain manager provides the foundation for fault, configuration, accounting, performance, and security (FCAPS) capability, thus enabling service providers to deliver a comprehensive, end-to-end management solution.

The Cisco PTC-VS Value Proposition

Cisco PTC-VS enables the rapid adoption of new packet voice network technology by providing network-management tools comparable to those in the PSTN environment. This helps simplify network management and enables integration of the new VoIP network for coexistence with the traditional PSTN, see Figure 1. Service providers are able to reduce costs by using the more efficient packet network and taking advantage of its value-added services.

Cisco PTC-VS offers virtual entity management for the packet voice network similar to that of the traditional time-division multiplexing (TDM) networks (to achieve logical functioning and usability equivalent). Cisco PTC-VS Version 3.1 adds support for the Cisco CallManager Express and the Cisco PGW Route Server Complex.

Cisco PTC-VS enables service providers to lower the total cost of ownership, improve business quality, accelerate delivery of service, accelerate time to revenue, and reduce customer turnover.

Cisco PTC-VS consolidates and simplifies VoIP network-management tasks by offering a consistent network service-provisioning model. Cisco PTC-VS is a potent management solution that provides holistic management of voice networks using virtual entity concepts (Figure 2), including:

  • Enterprises and sites that can be defined to represent the business voice service topology
  • A virtual SS7 gateway that deals with dependencies between an H.323 or MGCP gateway and a signaling controller in which SS7 traffic is converted to Q.931 signaling protocol for the gateway
  • A virtual zone that deals with dependencies between gateways within a zone as well as between gateways and gatekeepers
  • A zone connection that deals with dependencies between gatekeepers, or between gatekeepers and directory gatekeepers

Figure 2
How Cisco PTC-VS Manages Virtual Entities

In addition to providing support for virtual entities requiring consistent configuration of multiple network devices, Cisco PTC-VS supports configuration operations for an entire region, enterprise, site, or zone, giving users a means of performing high-density and bulk-provisioning tasks. For example, this feature enables an operator to apply a given gateway configuration to all gateways for a zone or region. In fact, many Cisco PTC-VS provisioning operations lead to multiple management requests issued to various managers and network elements behind the scenes to provide simplified, holistic virtual entity operation.

Network Management—Voice Routing

In addition to provisioning and topology, Cisco PTC-VS Version 3.1 adds the ability to manage voice routing dial plans for the elements described in Table 2, including the Cisco CallManager Express, the Cisco PGW Route Server Complex, gateways, gatekeepers, and directory gatekeepers in the H.323 network. Cisco PTC-VS enables administrators to design, configure, deploy, and manage dial plans in Cisco H.323 VoIP networks. Through its GUI, Cisco PTC-VS centralizes and coordinates call-routing configurations for thousands of VoIP gateways and gatekeepers within a single application. A good dial plan makes optimal use of network resources, ensures that all calls are routed appropriately, implements business rules for routing efficiencies, and minimizes PSTN toll charges. The dial plan can be the most complex part of the VoIP network to configure. Cisco PTC-VS accomplishes these dial-plan objectives via a wizard-driven user interface, reducing the complexity and simplifying the task of managing, adding, deleting, and modifying the dial plan.

Product Summary

In response to the critical need for an effective, comprehensive VoIP network-management tool, Cisco Systems® has delivered Cisco PTC-VS, engineered to provide vital functions for overall VoIP network management and service provisioning. Its multiaccess Web GUI empowers customers with a central entry point for complete network administration. Cisco PTC-VS can detect all physical network elements and create the virtual network entities or objects that are part of the voice service network. Detailed information about these elements is retained in an object model and is dynamically updated as events occur in the network, allowing Cisco PTC-VS to maintain synchronization and accurately reflect the network topology. The object model is critical to the creation and intelligent management of the virtual objects.

Cisco PTC-VS is designed with carrier-grade scalability, making it suitable for deployment in small-, medium-, or large-scale VoIP networks. Because VoIP technology deployments are increasing, Cisco PTC-VS is the perfect tool to significantly reduce the complexity involved in managing these packet voice networks, allowing technicians and engineers responsible for network management to perform simplified, end-to-end provisioning tasks. The Cisco PTC-VS open interface architecture offers access to customers' existing OSSs and eases efforts for third-party integration as well.

Cisco PTC-VS helps service providers realize considerably reduced network operations and management costs, reduced time to market for new customers and services, and reduced time to revenue, resulting in greater customer stability. Cisco PTC-VS contributes to increased revenue and a reduction in the service provider's total cost of network ownership.
