Clarinet BER Encoder Tool

Program Function

The Clarinet BER Encoder Tool allows you to encode ASN1 fields according to Basic Encoding Rules and to include the resulting string as content in a FACILITY information element in ISDN or QSIG.

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 editing of ASN1 facilities applied to ISDN, QSIG protocols.
  • Generation of hexadecimal ASN1 strings.

Installing the BER Encoder Program

The BER Encoder program is automatically copied by the Clarinet Run-time installation procedure (version 10.1 or greater). Under the Windows Start=>Programs menu, the Clarinet 11.x group includes the Clarinet BER Encoder shortcut providing access to the Berencod.exe program located in the Clatools directory.

Running the BER Encoder program

After launching the program from Windows, it displays a window on the desktop. The standard main menu includes a File and a Help menu. The editor toolbar includes functions to create and modify ASN1 content. 

Importing an ASN1 facility Template

The Clarinet Run-time package includes pre-written templates for QSIG Supplementary services. The files (extension .acb) are accessible via the File=>Import command and are located in the QSIG subtree of  templates.

Opening an existing ASN1 Facility File

The ASN1 content can be saved using the Save As command. The files can then be accessed using the File=>Open command and displayed according to ASN1 notation.

Other functions allow each line to be indented.

Generating a Hexadecimal String

The Generate BER encoding function generates BER encoding from the ASN1 content and displays it in the box at the bottom of the window. The hex string can then be copied and pasted into the Facility IE content (octet 3.1 and following ones). Octet 3 must be generated from the profile editor in QSIG profiles or ISDN profiles.
