Appendix C: G20 ISDN BRI Gateway

Introduction

The G20 ISDN BRI Gateway is a compact VoIP gateway router that supports two VoIP calls on
two ISDN BRI ports. This gateway allows your one-X Quick Edition network to leverage
low-cost Internet Telephony on existing ISDN phones for complete Single office/Home office
and branch office voice and data connectivity.
Figure 6 shows the position of the gateway in a typical company telephone network. Up to five
gateways can be connected to your one-X Quick Edition network if required to increase the
number of PSTN connections into your office.
Figure 6: Typical one-X Quick Edition Network Configuration
A typical configuration consists of a customer-supplied 10/100 Base-T Ethernet Local Area
Network (LAN) with a connected IP router or switch, to which the gateway and your telephones
are connected. An administration computer may be connected to the network to provide
web-based access to gateway configuration settings.
If your Quick Edition IP telephones are already connected to the LAN, adding a gateway to the
system is easy. Simply connect the gateway LAN port to an unused port on the IP router or
switch, and connect the ISDN BRI ports to the PSTN lines supplied by your service provider.
