File based HDLC Record/Playback over SA-bits


The File based HDLC Record/Playback over SAbits (SaBitsFunc) module is an optional application that allows receive and transmit of HDLC frames in *.hdl file format.


  • Receiving SA HDLC frames in HDL files

  • Transmitting SA HDLC frames from an HDL file

Syntax Notation

All the parameters must be entered in the order defined by the syntax. [parm] means that the parameter is optional and can be omitted.

Parm1|Parm2|Parm3 - parameter is mandatory, one of the choices Parm1, Parm2 or Parm3 must be specified

  1. Transmission of SA HDLC frames from an HDL file


    run task "SaBitsFuncE1:SaBitsTxFile" using " 'File_Name' CONT|EOF|N_frames [0xSM] [FLAGS nFlags] " .

    'File_Name' - name of HDL file in single quotes to transmit
    CONT - transmit file in round robin fashion (after the last frame transmit the 1st frame)
    EOF - transmit an entire file once
    N_frames - transmit N_frames. If file is shorter than N_frames start transmitting the 1st frame after the last frame till N_frames are transmitted
    0xSM - SA bit mask
    FLAGS nFlags - number of flags (0x7E) between frames to transmit


    run task "SaBitsFuncE1:SaBitsTxFile" using "'c:\test.hdl' 3 Flags 1000" #1;
    Transmit first three frames on card 1 with 1000 flags between frames

    run task "SaBitsFuncE1:SaBitsTxFile" using "'c:\data files\test.hdl' CONT" #1;
    Continuously transmit file c:\data files\test.hdl'

  2. Receiving SA HDLC frames into an HDL file


    run task "SaBitsFuncE1:SaBitsRxFile" using " 'File_Name' FileSize CONT|N_frames [FAS|NON-FAS] [0xSM] "

    'File_Name' - name of HDL file in single quotes to saved received frames to
    FileSize - maximum disk file size in bytes
    CONT - record frames in circular fashion, i.e. when the file capacity (size) is reached purge earlier frames.
    N_frames - receive up to N_frames.
    [FAS|NON-FAS] - FAS (default) receive in Frames 1,3,5.. , NON-FAS receive in frames 0,2,6,.. of each multiframe
    0xSM - SA bits mask


    run task "SaBitsFuncE1:SaBitsRxFile" using "'c:\test.hdl' 10000000 100000" #1;
    receive into file c:\test.hdl (allocate 10MB disk space for the file) up to 100000 frames SA4-SA8
