SmartNode Installation
45
Since both of the Ethernet interfaces of a SmartNode 1000 and 2000 series are fully configurable, it is
the application which defines whether an interface is used for WAN or LAN connections. For a
detailed description of the built-in interfaces for the SmartNode 1000 and 2000 series refer to
Chapters 1 through 3 of this manual.
Depending of the deployment scenario, optional interface cards are available for the expansion slots
of SmartNode 2000 series. For a detailed description of the available interface cards for the
SmartNode 2000 series refer to Chapters 4 and 5 of this manual.
Note:
For information concerning hardware and interface card support see the SmartWare Software
Release Notes for your Software Release and Build Number.
10.4 System Model of the SmartNode 1000 and 2000 Series
The system model of Inalp SmartNodes is depicted in Figure 10-1 and Figure 10-2. The devices have
three main components:
•
ISDN switching, with two ISDN Base Rate Interfaces.
•
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 Inalp 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.
