12 August 2003 Tel Aviv -- RAD Data Communications, a manufacturer of access solutions for data communications and telecommunications applications, has announced that sales of its TDM over IP (TDMoIP) Gateway, the IPmux, have increased five-fold in the UK compared to last year. No figures were given.
Demand for the IPmux, which enables carriers and enterprises to carry voice traffic over high bandwidth data networks, has soared due to the increased availability and price competitiveness of BT's wholesale LAN extension services (LES), which provide high data bandwidth for less than the price of a traditional E1 line.
RAD claims that any customer with voice and data connectivity between two sites or more can use its IPmux system to increase data bandwidth between sites. Voice services are integrated seamlessly into the data network regardless of signalling protocol, eliminating voice line rental costs and resulting in a return on investment in less than 12 months.
"The widespread availability and competitive pricing of LES services has enabled carriers and enterprises to access fibre networks," explained Grant Notman, UK General Manager, RAD Data Communications. "Until now, limited fibre access has been the greatest challenge to providing Ethernet services."
"This has led to an increase in demand for RAD's IPmux, a simple solution which enables customers to use their data networks for voice, without having to sacrifice the quality, reliability and functionality of TDM, or replace existing TDM voice switches."
Migration Path to VoIP
By allowing customers to use one backbone as a shared transport network for all services, RAD's IPmux reduces operational costs while preserving existing infrastructure investments, yet provides a clear migration path to Voice over IP.
The IPmux has been deployed by hundreds of customers in the UK over the past four years, including Highspeed Office and St Helens College, as well as numerous customers worldwide.
For lower bandwidth LES links or E1 lines, RAD's Vmux solution can be deployed. The Vmux supports voice compression and silence suppression, as well as TDMoIP multiplexing, allowing high quality voice services to be provided over low bandwidth networks.
Both the IPmux and Vmux are part of RAD's "Fast Payback" Programme, offering enterprise users a cost-effective solution for voice and data integration over LAN Extension Service (LES) circuits and E1 lines.
