Verso VCLEAR™ Class 4 Softswitch

A true IP alternative to traditional TDM-based networks that supports your network requirements for Class 4 Softswitch features

The VCLEAR™ Class 4 Softswitch is a next-generation call control solution for softswitch technology that significantly reduces capital and operating costs, reduces reliance for overlay networks, simplifies service provisioning, and enables new revenue-generating services.

An essential component in the migration to world-class IP communications

The VCLEAR™ Class 4 Softswitch is a highly flexible, carrier-class alternative to traditional tandem (Class 4) circuit switches. It offers carriers a cost effective way to transport voice and data protocols via IP packet while maintaining Quality of Service (QoS).

The VCLEAR™ Class 4 Softswitch is the central call control element of the VCLEAR™ PSTN Access Softswitch Solution. When deployed with the VCLEAR™ Class 5 Softswitch for "last mile" broadband networks, it enables service providers to interface with the traditional PSTN and provide off-net calling to any public telephone number in the world.

Complete Network Control

The VCLEAR™ Class 4 Softswitch's extensive functionality enables the network to:

• provide centralized, intelligent call routing logic for least-cost routing
• handle voice, real-time fax, and data traffic simultaneously, enabling you to deploy value-added services with maximum flexibility
• support pre- and post-paid calling card applications, Interactive Voice Response, multiple languages, and advanced subscriber services

Scalability and Flexibility

The VCLEAR™ Class 4 Softswitch is ideal for customers ranging in size from competitive startups with low-density requirements and rapid growth expectations, to tier-1 service providers requiring carrier-class solutions. It has the ability to achieve call capacities of more than 300,000 busy hour call attempts on a single server.

Reliability

Designed for carrier-grade availability, the VCLEAR™ Class 4 Softswitch is available on a NEBS-compliant, Unix-based platform, providing N+1 redundancy with failover capabilities. Active calls are maintained during platform switchovers, enabling upgrades without service disruptions.

Compliance

The VCLEAR™ Class 4 Softswitch supports emergency services (E911), ensuring that calls to emergency numbers take precedence over all other incoming and active calls, and that they are not disconnected. It also supports Location Routing Number (LRN) portability, so subscribers can change service providers without changing phone numbers.

Easy Configuration and Management

The VCLEAR™ Class 4 Softswitch can be deployed, configured, and managed remotely with the VCLEAR™ Element Management System, the web-based tool used for provisioning and managing all components of the Verso VCLEAR™ network.

At a component level, the VCLEAR™ Class 4 Softswitch supports SNMP with a comprehensive management information base (MIB), through which you can set configuration parameters, poll devices for performance statistics, check status information, and receive alarms, if faults occur.
