The DTP Series supports software configurable E1/T1/J1 interfaces, with spans of 1, 2 or 4 dual span taps per interface and can flexibly fulfill various call recording requirements. On-board advanced DSP algorithm and DMA processing capability permit the DTP Series to minimize host CPU resources and outperform other competitive products in the most stringent application scenarios. Better performance and higher scalability of up to [1200] (40 E1)-channels of simultaneous call logging. Making the DTP Series the reason many leading developers worldwide depend on the DTP Series to create robust high capacity call recording systems in complex central office as well as high-demand Telco environments.
