CIRPACK released software enhancements for its Class-5 telephony platform enabling wireline telecom operators to deploy TISPAN-compliant architectures. This allows migration of legacy PSTN to global VoIP networks capable of delivering new voice services such as fixed-mobile convergence according to 3GPP’s IP Multimedia Subsystem (IMS).
The TISPAN committee is the ETSI core competence centre for migration of fixed networks from circuit-switched to packet-based networks with an architecture that can serve in both.
In a TISPAN architecture, Cirpack switches control IMAP (Integrated Multiservice Access Platforms) using H.248/Megaco to deliver POTS and ISDN telephony from the same access platforms as DSL services. This allows operators to replace their legacy access networks while deploying broadband local loops and extend the reach of VoIP to the edge of their networks, without disrupting users’ installation and services.
Cirpack’s MultiNode-B is a highly modular Class-5 switch developed in collaboration with IBM.
