The Mediant 3000 media gateway offers up to 4,032 low-bit-rate VoIP/VoATM channels and SONET/SDH optical PSTN interfaces. Built with AudioCodes’ TP-6310 ‘Media Gateway on a Blade’ and AudioCodes’ VoIPerfect ™ architecture, the Mediant 3000 is able to provide maximum utility in a 2U compact footprint. The Mediant 3000 is expected to be available for initial customer trials in the third quarter of 2004.
