MPD-1,2 data transmission unit

The MPD-1, 2 data transmission unit is used for data transmission with high noise immunity over standard channels, radio channels and physical lines.

 

    Basic characteristics:

    1. Number of channels - 1

    2. Data rate - 1.2 kbps

    3. Number of subscribers in wire and radio communication network - 16

     

      4. Interface with DTE:
    • – type - RS-232C

       

    • – data rate - 9.6 kbps

     

     

      5. Methods to increase data validity:
    • – error-detection coding;
    • – error-correction coding;
    • – interleaving;
    • –decision feedback

     

    6. Volume of transmitted data packet - 1…64 bytes

    7. Probability of delivery of a 64-byte data packet with a signal-to-noise ratio in the communication channel of 6 dB - > 0.9

    8. Probability of undetected error in a 64-byte data packetwith a signal-to-noise ratio in the communication channel of 6 dB - < 10[sup]-6[/sup]

    9. Wre communication range - up to 30 km
