Configuring Frame Relay

Using the MultiVoice Gateway as a Frame Relay 
concentrator

In a Frame Relay backbone, every access line connects directly to a Frame Relay (FR) switch. 
In the past, most connections to the Frame Relay network were relatively high speed, (full T1 
or E1 lines, for example). With recent changes in Frame Relay pricing, many sites now want to 
concentrate many low-speed dial-in connections into one high-speed nailed connection to a 
Frame Relay switch. If you configure the MultiVoice Gateway as a Frame Relay concentrator, 
it accepts incoming dial-in connections as usual and forwards them out to a Frame Relay 
switch, as shown in Figure 7-1.

Figure 7-1.  The MultiVoice Gateway operating as a Frame Relay concentrator

As a Frame Relay concentrator, the MultiVoice Gateway can accept up to 96 low-speed 
connections in North America or Japan, or 120 low-speed connections in Europe. If all of the 
Frame Relay connections are concentrated onto the single 2 Mbps serial WAN interface, the 
MultiVoice Gateway turns a single high-cost Frame Relay port on a traditional Frame Relay 
switch into approximately 100 operational ports.
