Voice over Broadband harnesses the packet transmission principle, enabling multiple simultaneous calls and high-speed Internet accesses via a single line per subscriber. Using Voice over IP (VoIP) technologies, broadband operators worldwide are now deliver voice services of comparable and sometimes higher quality than PSTN services.

Some operators are promoting broadband telephony as secondary line service aiming at enriching their broadband offerings. Others are using VoIP as a primary line telephony service designed to replace the legacy POTS service and become the sole provider of telecom services to their subscribers.

Primary line telephony using VoIP

Thomson’s Cirpack switches are at the heart of some of the largest European VoIP services such as Free.fr, Telecom Italia and T-Online. They have proven their superior scalability and reliability in delivering primary line telephony over broadband local loops: DSL, Cable, WiMAX, Fiber, etc.

Because they have been designed to match the legacy PSTN requirements, Thomson’s Cirpack switches deliver the right telephony features to replace the legacy fixed line service with the same user experience in terms of reliability, quality and additional services. The Cirpack platforms even support lawful intercept, emergency numbers and local number portability for full compliance with regulatory requirements.

Enhanced with IP Centrex and Fixed-Mobile Convergence capabilities, Thomson’s Cirpack switches help small, medium and large telecom operator to promote feature-rich broadband services bundled with unique telephony services such as Hosted-PBX for small offices and Wireless VoIP to literally travel with your fixed line.

IP Voice Termination

Thomson’s Cirpack telephony platforms are the ideal transit switches for VoIP carriers. Their superior design makes it possible to deploy wide infrastructures with many nodes close to PSTN termination points, while leaving considerable scope to scale up to support traffic growth. They support a wide range of legacy protocols to connect to the PSTN in any manner, including nearly all SS7 variants (ISUP, TUP, etc.), as well as Primary Rate Interface (ISDN PRI) and R2 signaling. They also handle both SIP and H323 signaling to peer with any other VoIP carrier and use the best route for each call.

Thanks to Cirpack platforms’ advanced routing features (e.g. dynamic routing, trunk reselection, least cost routing, call duration control for pre-paid, etc.), wholesale carriers can deploy feature-rich transit networks at very low cost without compromising on power and reliability.
