VENTELO CHOOSES A TDM PSEUDOWIRE SOLUTION FROM RAD DATA COMMUNICATIONS TO PROVIDE PSTN ACCESS OVER IP DSLAMS
06 June 2007 - RAD Data Communications Ltd

Ventelo has decided to expand its portfolio of services for enterprise customers by taking advantage of the multiplicity of IP DSLAMs in those countries. To do so, Ventelo opted for a solution comprised of RAD's IPmux-11 TDM-over-IP pseudowire access gateways working in tandem with its

Gmux-2000 central site TDMoIP pseudowire gateway and its LA-110 Ethernet-over-DSL Integrated Access Devices.

Making Telecom History'Traditionally, alternative carriers transport PSTN traffic over expensive leased lines,' explains Mati Epstein, Director of Sales for Scandinavia at RAD Data Communications. 'Ventelo is making telecoms history by offering the same service using TDM pseudowire and IP DSLAMs.'

In the Ventelo application, IPmux-11 units are used to encapsulate PBX traffic for transport over a low-cost Ethernet link. This emulated TDM traffic is then passed over SHDSL links by LA-110 IADs to an IP DSLAM, which concentrates several similar connections, and forwards them across the packet switched network. At the other end of the PSN, a Gmux-2000 TDMoIP pseudowire aggregator is used to reconstruct emulated TDM traffic back into TDM signals for transmission over the PSTN. This solution replaces the need for Ventelo to be running TDM voice over more expensive leased lines.

'We can convert TDM PBX traffic for transport over Ventelo's own high-quality IP network in order to reduce cost, and obtain full end-to end control of the service, while the customer experiences the same high quality and functionality,' says Helene Ålander, Director of Network Services at Ventelo. 'Ventelo can, through the solution, offer more attractive products to our customers in a very competitive market,' she adds.

Reduces Network Expenses Without Compromising FunctionalityTDMoIP pseudowire technology, developed and pioneered by RAD, is an evolutionary approach for transporting circuit-switched telephony and legacy data transparently over PSNs while ensuring strict priority for the TDMoIP traffic over the network link. In so doing, all the features and functionality of today's class 4 and 5 switches and SS7, PRI and other signaling protocols are maintained. This enables carriers and enterprises to reduce network expenses without compromising functionality or scope of services.
