The BER-Encoder program is provided as an additional Clarinet tool delivered in the Clarinet Run-time Package. It supports the following functions:

  • file management: saving, importing templates.
  • line edition of  ASN1 facilities applied to ISDN, QSIG protocols.
  • generation of Hexadecimal ASN1 strings.
