    It can be configured to transmit analog, digital or both analog and digital channels simultaneously, including teleprotection. When working with analog channels, the OPU-1 terminal can transmit one or two 4 kHz standard channels in each direction. The effective band of each channel, from 300 Hz to 3850 Hz, can be used for the transmission of data at high speed, various VF telegraph channels, teleprotection signals or for a speech-plus service.
  • Page 6 16 kHz. At 20.25 kbit/s, the transmission and reception channels, each of 4 kHz, can be adjacent, resulting in a total bandwidth of 8 kHz. When working with a QAM digital channel, the OPU-1 can integrate teleprotection signals in the digital operation band.
