TEC (Telephone Electronics Corporation), the USA’s largest privately owned corporation in the telecommunications arena, has subsidiaries spanning the entire spectrum of communications and provides telephone services to millions of people daily. To accommodate its growing base of customers, TEC applies the most modern and innovative technologies. TecNet, a TEC subsidiary, provides interexchange carrier (IXC) and international call center services (shared usage call centers) in countries such as India and the Philippines. Recently, TecNet needed to add international voice trunking capacity to accommodate growing remote call center applications. “This need could be fulfilled by expanding existing voice compression systems by adding voice compression and data link modules to our existing systems,” explains Jim Savage, Director of Operations and Engineering at TecNet. “But upgrading traditional voice compression equipment is expensive and the existing technology only provided for 8:1 compression. TecNet’s goals were to reduce capital expenses with more costeffective equipment and halve our international private line expenses by doubling the voice compression ratio over leased lines. The Vmux-2100 achieved these goals easily.”  TecNet also wanted a solution flexible enough to work over other network types, such as satellite and IP, and provide redundancy when needed. “The equipment needed to be simple enough to deploy at remote call centers that have limited technical support staff, a capability delivered by the user-friendly Vmux-2100. Furthermore, since call center functionality could not be compromised, all PBX or telephony server features, such as automatic call distribution (ACD) for incoming customer service calls and predictive dialing for outgoing sales/marketing calls, needed to be supported transparently,” Savage adds. “Another appealing feature is the Super Tandem capability, which prevents repeated compression and decompression of calls connected via multiple Vmux units.” “With RAD’s Vmux-2100 solution, savings are dramatic. For example, the ROI is less than one month when replacing 16 E1 lines from New York to India at a typical cost of $8,000/month each, with a pair of Vmux-2100 units and a single E1 line,” notes Eitan Schwartz, Vice President and General Manager of TDMoIP at RAD Data Communications, Inc. “In TecNet’s case, they purchased Vmux-2100 units with 16 E1 capacity and 16:1 compression for about the same price as an eight E1 upgrade to their older 8:1 voice compression equipment. This means they doubled capacity without additional line charges or realized annual savings of approximately $96,000 per E1,” Schwartz adds.  “Cost savings have been immediate, and the RAD solution greatly reduces our power and floor space requirements because of its compact 1U size, whereas our previous system required half a rack bay per system,” notes Savage. “We are completely satisfied with the product and look forward to acquiring more of them as our business expands.” |
