Digium has designed the TE410P to be fully compatible with existing software applications and it is fully integrated with the Asterisk Open Source PBX/IVR platform. Also, the open source driver supports an API interface for custom application development. With the combination of Digium Hardware and Asterisk software, numerous combinations of telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications.

The TE410P supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, also included are advanced call features.

Digium cards are smarter! Second-generation firmware for Digium multispan TE-series hardware PCI cards, provides several new features. These features allow Digium cards to do more work in hardware and leaving the server's CPU open to do other tasks, all of which contribute to less CPU overhead, and therefore improved performance, and more channels running through a single PC or server.

• TDM channel alignment in hardware (instead of software), for greater voice integrity and reliability.
• Master clock source distribution for synchronized timing across multiple cards, assuring synchronization of clocks and increasing reliability and quality of data transmission.
• Zero-latency TDM direct hardware-level cross-connect
• Support for new echo-cancellation module which further increases performance.
• DTMF detection can be done in hardware with echo cancellation module.
• Field upgradable firmware for future updates.

The TE410P supports a 3.3v PCI slot only - typically available on newer motherboards and in 64-bit PCI bus architectures. The TE405P is for use only with a 5.0 volt PCI slot.
