Model 69320-001 Voice Network Adapter General Information This data sheet applies to the Model 69320-001 Voice Network Adapter (VNA), which allows voice communication between interconnected SmartSeries systems. It is installed in a 10457 Series Card Rack and is controlled by a 69254 Series or 69440 Series Master Control Unit (MCU) installed in that same card rack. The VNA is designed exclusively for use in a SmartSeries system, and is not intended for use with other types of equipment. The front panel LEDs provide indication for the VNA and system status.
