The duoBRI ® miniPCI 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 (see Application 1).
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® miniPCI 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 4 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.
The miniPCI form factor is the ideal base to build highly integrated and cost effective
Voice over IP gateways and PBX solutions.
