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 IMACS in this environment is in bundled service arrangements where the IMACS is utilized to integrate voice circuits and an Ethernet-based Internet port at the customer location as shown in Figure 39. 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.

Private Intranet Deployment

A secondary market for the IP Routing Server is private Intranet access. In the application shown in Figure 40, the IMACS on the left is connected to a private WAN. It has a single connection to a centralized router, which provides full IP routing functionality. The IMACS on the right has two T1 connections, one to each of the two remote IMACS, and one connection to the router. Normally, there would be two connections to the router. However, in this application, the IMACS on the right includes a Frame Relay Server card, which switches both frame relay streams into the router.
