SmartNode 1000 and 2000 Series Getting Started Guide
2 • Product Overview
Figure 32 depicts a SmartNode 2000 series used as a voice gateway and IP router in an 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 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.
