3.2 SmartNode Hardware Platforms
The SmartNode series of devices covers a performance range varying from that suitable for small
office/home office (SOHO) applications to large corporate sites, or in terms of voice channels from 2
channels (one BRI/So) to 60 (two PRI/S2m). The SmartNodes comprise two classes:
•
The SmartNode 1000 series compact devices with fixed configured on-board ports
• The SmartNode 2000 series with on-board ports plus expansion slots for individual interface
configurations using a range of optional interface cards (IC).
The basic system model of a Inalp Networks AG SmartNode is depicted in Figure 3-2. Both the
SmartNode 1000 and the 2000 series have three main components:
•
64k circuit switching is supported between on-board ISDN ports and on and between ISDN
and PSTN interface cards. The circuit switching engine uses dedicated hardware resources
and therefore can bypass the VoIP gateway and packet routing engine.
• Gateway (GW), which converts 64k circuits into Internet protocol (IP) packet streams and
vice versa. Voice over IP is supported according the H.323 standard and via Inalp Networks
AG’ patented ISDN over IP (ISoIP) protocol.
• IP Router, with on-board ports and optional data interface cards. The router is QoS enabled
allowing classification, shaping and scheduling of multiple service classes.
