Distributed systems

To address the needs of the very large organization, including very small locations, Alcatel provides

substantial network capacity:

Distributed Media Gateways

In the Alcatel OmniPCX Enterprise distributed architecture, various cabinets and chassis, called media

gateways, provide for all traditional voice end-point connections (i.e., analog, digital, wireless and soft

phones, and PSTN / trunk interfaces), system resources (e.g., conference and tone generation/

detection circuits), auxiliary devices and also provide local switching for voice end-points and

resources within the media gateway.
