Figure 2-2: Typical Enterprise Network
Figure 2-2 shows the deployment of SmartNodes in enterprise networks. Each site (headquarter,
branch or home office) is equipped with a SmartNode that connects the local LAN and telephony
infrastructure with the IP WAN and the local PSTN carrier.
2.4 LAN Telephony
With its Voice-over-IP gateway features the SmartNode can be used as a standalone gateway for
H.323 LAN voice systems such as LAN based PBXs or call centers.
A standalone gateway has performance reliability and scalability advantages compared with PC -
based gateway cards. In this application the SmartNode also offers a migration path to enterprise or
carrier networking.
Figure 2-3 shows the deployment of a SmartNode as a LAN voice gateway.
The PSTN connections can be scaled from a single ISDN basic rate access to multiple primary rate
lines. With Q.SIG integration in private PBX networks is also supported.
