4 Installing the QX Gateways
4.1 Networking Overview
To establish connections between the PSTN (or the legacy PBX) and the Internet, a gateway is needed. The QX
gateway, used as a stand-alone device, will perform the task of connecting the PSTN (or PBX) to a Private Data
Network or the Internet. The QX gateway will process and regulate the voice traffic between these networks
according to specified dial plan.
