As a proud milestone in call recording hardware design, the DTP series is E1/T1/J1 interface software configurable, supports 4, 2 or 1 dual span taps per slot, and can flexibly fulfil various requirements. Specifically, by providing on-board advanced DSP algorithm and DMA processing capability, the DTP series helps minimize host CPU resources and outperforms all competitor products in the toughest application scenarios. This includes better performance and higher scalability up to 960(32E1)-channels simultaneous call logging. For these reasons many leading developers worldwide depend on the DTP series to create robust high capacity systems in complex central office as well as high-demand Telco environments.

With multiple signalling capabilities and high compatibility with international standards, the DTP series has been widely used as a reliable and cost effective tool by call recording application developers to passively tap E1/T1/J1 networks in a variety of complex telephony environments. Used by the leading call recording solution providers since the 1990s, the DTP series has been optimized to fit the toughest demands and most competitive environments because of its unrivalled cost advantages and world class robustness.

The DTP series also leverages dedicated DSP chipsets to process a range of high-ratio compressions, such as license-free G.729 and GSM. This robust architecture further releases host processor resource from overloading and assures efficient data storage and high robustness for data transmission in the most difficult situations. The DTP series provides call logging application developers with a complete range of options, portfolios containing half/full length, E1/T1/J1 configurable, CAS/ISDN/SS7 protocols and more versatility. Conveniently DTP series can be installed into most server categories and computer types. All of its new-generation portfolios are PCI-express form factor, half-length card.

Key Features & Benefits
