Figure 10-5 depicts a SmartNode 2000 series used as a voice gateway and IP router in a SME
situation.
The optional IC-4BRV interface card’s BRI 2 port is used as an ISDN fallback interface. In case of a
power failure, 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 interface card, providing up to six concurrent
ISDN B-channels. The voice data is transferred via the integrated voice gateway in the SmartNode
