System model of the SmartNode 1000 and 2000 Series
The system model of Patton SmartNodes is depicted in figure 28 and figure 29 on page 53. The devices have
three main components:
• ISDN switching, with two ISDN base rate interfaces (BRI).
• Gateway (GW), which converts ISDN voice data into Internet Protocol (IP) data streams or voice over IP
(VoIP) and vice-versa. VoIP speech is supported according the H.323 standard and via Patton Networks’
patented ISDN over IP (ISoIP) protocol.
• Router, with on-board Ethernet and other data interfaces which support quality of service (QoS) classes and
type of service (TOS) bit setting. Quality of service enables the router to support multiple traffic classes.
Voice routing
Via its gateway, an Patton SmartNode 1000 and 2000 series device can carry voice data between the ISDN
basic rate or primary rate interfaces and Ethernet or other data interfaces. This facility allows a wide variety of
voice routing scenarios to be realized.
