The ZTAP is the latest in Microsemi CMPG's hardware platforms designed to provide a demonstration and development vehicle for Microsemi CMPG's voice devices. In standalone mode, it operates as a basic call control environment that will automatically run Microsemi CMPG line modules. When used with Microsemi CMPG Toolkit, devices/lines can be monitored and programmed with user specified parameters. Voice quality measurements can be made in either E1 or T1 mode by connecting standard test equipment to the ZTAP.
