AMUR-PCI-BRI-6

Цифровое устройство многоканальной длительной звукозаписи цифрового протокола «AMUR-PCI-BRI-6»

Purpose:

Digital device multichannel audio digital protocol prolonged «AMUR-PCIBRI-6" - a software and hardware system, which provides a record to your hard drive, playback and analysis of analog audio information transmitted on digital telephone systems. The device is installed in the computer. On a board connected to 6 lines 2B-1D (1B-1D). Controls up to 12 telephone channels. Recording channels in stereo mode (separately for each subscriber.) This allows you to select each user separately for the purpose of identification, and produce automatic alignment signal levels near and distant subscribers.
