Routing Server Applications
2.10.1 Bundled Service Deployment
The IP Routing Server is targeted at performing boundary routing functions for access to
Internet or Intranet based services. The standard application for an IAD in this environment is
in bundled service arrangements where the IAD is utilized to integrate voice circuits and an
Ethernet-based Internet port at the customer location as shown in Figure 2-29. The carrier
would typically switch the voice circuits to the PSTN via a DACS, while the frame relay based
data connection from the Ethernet port would be connected to a Frame Relay network for
transmission to the Internet. An external firewall can be used for providing and maintaining
security when connected to the Internet.
