The IC-4BRV is a PMC standard compatible interface card for the SmartNode 2000 series. It provides 4 ISDN BRI interfaces and connects through a PCI packet and PCM circuit interface to the SmartNode base unit.

The IC-4BRV supports up to 8 simultaneous voice or fax calls. It is a flexible ISDN networking card designed to meet the needs of small enterprises that want to connect their ISDN equipment, such as an ISDN PBX, via multiple BRI interfaces to a multi-service IP network.

The ISDN interfaces can be configured as user or network side interfaces. Its on board dedicated micro-controller and DSPs offload the CPU of the SmartNode 2000 base unit and hence guarantee the conversion of voice/fax circuits into related IP-packets in real-time and with least delay and jitter values.

Configuration Example
The example shows the connection of a PBX via an IC-4BRV Card in a 2Net : 2Usr configuration into an IP Network.
