Overview

The VX400 platform supports analog, digital, and native IP voice, as well as port and trunk side serial data, making it a compelling solution for any government agency looking to deploy IP-based voice and data solutions. The product line combines the functionality of a media gateway, signaling control point, H.323/SIP inter-working device, media server and voice/data mux in a single chassis. As a port side interface, the optional serial data card enables legacy equipment to take advantage of the IP backbone, realizing full convergence.

Features

The VX400 uses dynamic flow control technology to overcome the challenges of maintaining secure VoIP calls in a degraded environment. The platform will keep secure calls connected even when the network experiences slow traffic flow and significant packet loss. Other implementations "relay" secure traffic as a normal (high bit rate) compressed audio call. Any lost, late or corrupt packets often result in the modem carrier slipping, causing the modem to retrain which typically results in a dropped call. The VX SERIES can withstand significant packet loss and jitter, and still keep the calls connected. FNBDT calls on VX400 can withstand complete network failure for up to 10 seconds without failing the call.
