B200 Series

The OpenVox B200 series offers 2 S/T BRI interface ports. Both BRI ports can be individually configured in TE or NT mode via jumpers. This port configuration is automatically detected by the driver. It makes full use of the hardware echo cancellation module based on Siemens® technology to provide superior voice quality on the BRI ports.

The B200 series S/T BRI interface card delivers superior voice quality in telephony systems thanks to a hardware echo canceller based on Siemens® technology. It transforms your existing ISDN BRI equipment into powerful Voice over IP devices and offers a smooth migration path from ISDN technology to the world of Voice over IP.

The B200 series brings powerful ISDN BRI connectivity to your Linux machine. It comes with full GPL drivers for the Linux kernel. Multiple B200E cards can be interconnected via an external PCM bus. The card’s active channel switching capability also works on the external PCM bus. The B200M, designed for low-power systems, consists of two parts: the B200MM and the B200MS. The B200MM connects to a Mini PCI slot while the B200MS provides the S/T BRI interface connection. It supports Mini PCI III type.

The B200 series works with Asterisk®, Elastix®, FreeSWITCH™, PBX in a Flash, trixbox®, Yate™ and IPPBX/IVR projects, as well as other open-source and proprietary PBX, Switch, IVR and VoIP gateway applications.
