RAD - Products

Carriers and enterprises are looking for ways to reduce costs by transporting their voice traffic with greater bandwidth efficiency. This can be achieved by using state-of-the-art voice trunking and compression algorithms which maintain toll-quality voice, and by converging voice and data traffic over packet-switched networks, or by using voice over IP standard solutions.

Voice Trunking

Long distance and international leased lines are still quite expensive in many parts of the world, especially satellite-based communications. Reducing the amount of bandwidth required for voice transmission can significantly reduce Opex. RAD’s voice trunking gateways use state-of-theart voice compression algorithms, as well as silence suppression and RAD’s unique TDMoIP multiplexing, to reduce the amount of bandwidth required for voice transmission by up to 16 to 1. This translates into significant reduction in Opex, while maintaining toll-quality voice, and without compromising signaling, fax and telephony features.

Benefits of RAD’s voice trunking solutions

• Significant bandwidth reduction (up to 16:1) translates into significant cost savings

• High quality voice

• Full transparency to signaling and telephony features eliminates the need for additional capital expenditure or retraining of staff

• Future-proof solution, equipped with both TDM and IP network links

• Reduce initial investment with scalable products that are simple to install and maintain

Typical applications

Inter-MSC Trunking – Typically hundreds of long haul links are used to transport traffic between MSCs (E-channel) in meshed, star or mixed network topologies. Limiting the number of links translates into immediate cost savings. RAD’s Vmux/Gmux voice trunking gateways use advanced voice compression technologies to significantly reduce the number of required leased lines. This savings translates into fast payback.

Offshore call centers – The cost of international leased lines is still a large contributor to the overall Opex involved in operating an offshore call center, especially one with thousands of seats. Using RAD’s Vmux voice trunking gateways, providers of offshore call center services can significantly reduce their operational costs, without degrading the level of service they provide.

PBX extension over satellite – Providing voice services to remote/mobile platforms usually involves satellite communications, which significantly increases Opex for the oil/gas, maritime, broadcasting, emergency response, and government/military industries. RAD’s Vmux voice trunking gateways increase the capacity and reduce the cost of extending voice services over satellite.

VoIP

The rapid advancement in broadband deployment is creating new opportunities for both service providers and enterprises to benefit from converged voice and data networks and cost-cutting Voice over Internet Protocol (VoIP) services. The RAD VoIP System (RVS) enables seamless transition to IP telephony, leveraging existing equipment to tap into the savings and advanced technology available from VoIP communications. An invest-as-you-grow platform, the RVS has been designed to enable VoIP services at a low initial ownership cost. Consisting of customer premises equipment (CPEs), a central softswitch and a management system, the RVS is an out-of-the-box solution that enables providers to launch a VoIP service in days. A SIP-based, carrier-grade solution, the RVS has been engineered for quality, reliability and scalability – key factors when rolling out a VoIP service

Benefits of RAD’s VoIP System

• Fully integrated system controlled by single management system

• Zero time to service • Low initial investment – “pay-as-you-grow” model

• Unique remote analysis tools save on truck rolls

• Compatible with all standard SIP clients

Typical application

VoIP telephony access – Traditional voice access services were provided to business and residential customers by TDM Class 5 switches. The costs of TDM resources are extremely high compared to an IP-based solution.

RVS provides all the essential parts of a VoIP access service: management and provisioning, softswitch and a variety of smart CPEs that enable the telephony service provider and the end user smooth migration to IP-based access services with tremendously low costs and high Availability of Service.
