Figure 32
depicts a SmartNode 2000 series used as a voice gateway and IP router in an SME situation. The
optional IC-4BRV-8V interface card’s BRI 2 port is used as an ISDN fallback interface. In case of a power fail-
ure, equipment connected to port BRI 1 is bypassed with a relay to interface BRI 2. It remains operational
even if the SmartNode 2000 series is not powered. Three ports of the PBX are connected to the remaining BRI
ports of the IC-4BRV-8V interface card, providing up to six concurrent ISDN B-channels. The voice data is
transferred via the integrated voice gateway in the SmartNode 2000 series over Ethernet port ETH 0/0.
Depending on the call procedures defined by the software running in the SmartNode 2000 series, voice data is
formatted as H.323 compliant or as ISoIP voice streams.
