The duoBRI® PCIe ISDN turns your legacy ISDN equipment (or analog equipment behind an ISDN TA) into powerful Voice over IP devices. It provides a soft migration path from ISDN technology to the new Voice over IP world.

Connect your ISDN PBXes at different locations with Voice over IP and drop costs for company internal calls close to zero. Transparently add least cost routing over ISDN or VoIP carriers to reduce costs on outbound calls significantly.

The duoBRI® PCIe ISDN brings powerful ISDN BRI connectivity to your Linux machine. It comes with fully GPLed drivers for the Linux 2.4. X and 2.6. X kernels.

All 2 BRI ports can be configured for TE or NT mode individually by jumpers. This port configuration is detected by the driver automatically.

The drivers can handle the user and network side of euroISDN (ETS 300 102) signalling, support for National ISDN 1 (Q. 931) is planned.

Multiple duoBRI® PCIe ISDN cards can be interconnected over an external PCM bus. The card?s active channel switching capability (to bridge B channels on the card without latency and not using the host CPU) is also working over the external PCM bus (e. g. B channels on different cards can be actively switched).
