Patton electronic SmartNode 4110 Series SmartWare embedded software, Circuit Switch, VoIP Gateway

SmartWare Software Configuration Guide 1 • System overview

Figure 1 depicts the basic system model of a Patton SmartNode. All SmartNode devices have the following main components:

•64k circuit switching between on-board ISDN ports 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.

•A gateway (GW) that converts telephone circuits into Internet protocol (IP) packet streams and vice versa. H.323-compliant and SIP Voice over IP (VoIP) is supported.

•An IP router with on-board ports and optional data interface cards is QoS enabled, thereby allowing classi- fication, shaping, and scheduling of multiple service classes.

For more detailed hardware information, refer to the getting started guide that came with your Smart- Node system.

SmartWare embedded software

SmartWare is the application software that runs on the SmartNode hardware platforms. SmartWare is available in several releases. Refer to SmartWare release notes for detailed information about hardware support.

A SmartWare build is a binary image file. It is usually divided into several checksum-protected files to improve download efficiency and security. The download to the SmartNode is handled in sequence by using a down- load batchfile. Refer to chapter 5, “System image handling” on page 65 for details on SmartWare image down- loads.
