The Sonus GSX 4000 Low/Medium-Density Media Gateway delivers carrier-class reliability and performance in a rack-mountable server ideal for Class 5, enterprise and Local Exchange Carrier (LEC) deployments. With its small footprint and low energy consumption, a single GSX 4000 softswitch solution can dramatically reduce network operating expenses. And with its low price point, the GSX 4000 gateway ensures that service providers and enterprises pay only for the performance they need. Despite its small size, the Sonus GSX 4000 gateway delivers the same voice quality and transcoding features as the larger GSX 9000 gateway, including robust protocol and codec support for TDM, IP, GSM, CDMA, 3G and 4G networks.
