UNIVERSITY OF VIENNA CHOOSES TDMOIP FROM RAD SOLUTION
21 June 2004 - RAD Data Communications Ltd

The RAD equipment, which connects 23 separate locations, enables the convergent transmission of voice and data over a Gigabit Ethernet infrastructure. One factor that was particularly important for the university in choosing the RAD solution was that TDMoIP does not require existing TDM-based telephone systems to be replaced by expensive Voice over IP systems nor expanded at great effort and cost.

In 2001, requirements for increased bandwidth led the Viennese university to replace the existing fixed lines then used for data transmission with dark fiber lines leased from various providers. The university now operates its own GbE network via this dark fiber infrastructure. With dark fiber, however, only the optical fiber is leased as a physical transport medium from a service provider. Switching and management are the responsibility of the lessee.

VoIP Too Expensive"In order to utilize the dark fiber lines as optimally as possible, we also looked for an economical solution to transmit telephone calls between the locations over the new GbE infrastructure," stated Markus Ankner of the central IT service at the University of Vienna. "As a result, the existing leased 2 Mbps voice lines became superfluous," he continued. "A new VoIP-based solution was not an issue, since the necessary investment for the telephone network would have been too high," Ankner explained. "Using TDMoIP to connect our existing telephone system to our new high-speed network appeared almost too easy to us at first, but in view of the impressive test results, especially given the excellent voice quality, it didn’t take long to convince us of the benefits."

TDMoIP enables all TDM-based data to be transmitted transparently over IP, Ethernet and MPLS packet-switched networks. "TDMoIP technology provides an ideal alternative to Voice over IP," noted Christian Gerwig, Product Manager at CS Communications & Systems Austria GmbH, the RAD distributor partner that first proposed the TDMoIP solution to the University of Vienna. "By transmitting TDM data over GbE, universities and other operators of large networks, such as corporations and government offices, can reduce line costs without undertaking additional investment in expensive upgrades of the existing telephone systems and LAN infrastructure, or even the acquisition of an integrated softswitch-based VoIP system," Gerwig added. "TDMoIP proves its unbeatable cost benefit by its favorable price structure, its simple installation and its high degree of reliability."

In addition to high speed data applications, some 8,000 employees and numerous students currently use the new network for cost-effective and high-grade telephone connectivity between 23 university locations. This has become, therefore, one of the largest installations of convergent networks in all of Austria. Other Austrian universities have expressed interest in TDMoIP as a result.

TDMoIP Gets High Marks From Educational InstitutionsWith increasing frequency, educational institutions around the world have chosen RAD's TDMoIP technology over VoIP. TDMoIP solutions are being used, for example, in the Ecole Nationale Supérieure des Télécommunications in Paris, Coleg Gwent in Wales and the Spokane school district in Washington state in the northwestern U.S. "When we explain TDMoIP to our customers, they are often surprised how easily they can connect their conventional telephony systems to packet-switched networks such as Fast and Gigabit Ethernet," said Tal Gilad, TDMoIP Product Line Manager at RAD Data Communications. "This is particularly true of campus environments and networking locations within a metropolitan area."

RAD's IPmux TDMoIP gateways are suited for the carrier market as well as for corporate networks. The range of applications includes the connection of conventional telephone systems and data transmission equipment to company-owned or public packet networks and the emulation of conventional fixed lines for transmission to packet-based transport networks. The equipment is suitable for voice, video, telemetry and data services. Typical ISDN telephony features, such as SS7, can also be transparently transmitted.
