Telindus designed and developed a complete voice-band modem for use in embedded applications. It can be delivered as a standard mounted unit (socket modem), or as a reference design.
 
The modem does not require any micro-controller and is fully based on soft-coded DSP algorithms developed by Telindus. Therefore, it offers a more flexible and cost-effective alternative for the more rigid modem-chip solutions.
 
The modem design offers very low operating power requirements and a small form factor, making it ideal for many applications, such as embedded control systems, communications for instrumentation equipment, set-top box, Internet TV, email phone and portable communications equipment.
 
The socket modem communicates with standard RS-232 serial interface with the  embedded applications. Upon power up or reset of the chipset, the modem code is loaded from flash memory into the modem DSP internal memory. The end user can now communicate with the modem through the serial interface using industry-standard AT commands.
