  • Page 25: Choosing The Linear Encryption

    To make the optimal choice for the bitrate, the parameters of the line intended for the modems are to be taken into account. In case the line parameters are unknown, the following procedure is recommended to choose the bitrate: • Measure the line resistance with an ohmmeter (at one side, the wire pair is short-circuited and at the other side the measurement is carried out) and use Table 2 of Appendix to define the bitrate...
  • Page 26 Therefore, when setting up the bitrate of the communication line, special attention should be paid to the encryption algorithm TCPAM and, when necessary, the linear coding should be altered in order to produce the best possible results. In diagram 1, the permissible ranges of TCPAM encodings are shown. Diagram 1 192 Kbps 3840 Kbps...

    The commands plesio, plesio-ref, sync are used to set up the mode of synchronizing modems. In case the communication route is formed of modems Sg-17B<->Sg-17B, the mode of synchronization «sync» is recommended. Otherwise, modes «plesio» or «plesio-ref» are preferable, the choice being determined for each specific communication line empirically.
