Description

The Large Digital Switch (LDX) is an advanced digital switch allowing the users to build up to 2048 channel non-blocking switch. The serial interface can be at 2, 4 or 8 Mb/s compatible to ST-BUS/MVIP/HMVIP or GCI standards. The LDX can be programmed to provide either minimum or constant throughput delay on all its channels. The device also features three-state control and message mode on per-channel basis.
