Telephone Interface

MediaMatrix TPU units connect to a NioNode via an RS-232 cable. Each TPU can be programmed using an NWare TPU device to automatically answer phone calls. The user interface also provides a ring indicator to inform the user that the line is ringing and a box for entering phone numbers to dial.

You can use the Snapshot device in NWare to preload telephone numbers for preset calling. DTMF codes that are received via the NioNode can be decoded using the DTMF Decoder device.

Note: In order for the NioNode and TPU unit to communicate, the RS-232 port on the NION must be set up so that console mode is disabled. For more information on configuring the port, refer to the section Specifying the function of the RS-232 serial port in the NION Hardware Manual.

Tip: NWare only provides a basic interface to the features of MediaMatrix TPU devices. You can use the command line interface to the units to perform further functions. For more information, refer to the product documentation supplied with the units.
