Hi all,

I am new Lavastorm user and I am trying to parse an ASN1 binary CDR (Call Data Record). I have the ASN1 definition file that I need to use. I don't know which LDR nodes to use and how i should link them.

I would appreciate any help.

Thank you all.

Hi,

As of LAE 4.6, The LAE comes packaged with the LDR.
Previously this required a separate installation after purchasing the LDR.
Even in LAE 4.6, however, in order to use the LDR you need to have an LDR license.

This is an add-on component that can be purchased in addition to the LAE.
If you do not have the software license for this (either because you have not purchased it, or have simply not received the required "Node Pack" software license from Lavastorm), you should contact your Lavastorm support/sales representative.


There are 3 libraries (BRGs) that come with the LDR:

1. dataAcquisition - can be used to write readers by writing an XML specification to describe the data
2. asn1 - used to read ASN.1 data with an ASN.1 specification
3. cobol - used to read COBOL data with a COBOL specification

You would want to use the asn1 library.

To use these nodes, you simply need to add the asn1 library as a base library (using Graph->Edit Base Libraries).
Nodes should then appear in your node palette under "Acquisition->ASN.1" and "Interfaces and Adapters->ASN1"
If you are not licensed to use these nodes, they will appear to be "locked" with an icon over the nodes which indicates you are not licensed to use them.

If these nodes do not appear as locked then you have the required node pack license and are able to use the nodes.

In this case, there are detailed instructions on using the LDR within the LAE in the LDR Tutorial located in your <Client Install Dir>/docs/ldr/tutorial/LDR Tutorial.pdf.
The tutorial covers all of the basics for getting setup to configure your own data readers, along with sections on how to configure nodes to read ASN.1 data.

If you are just interested in reading ASN.1 data, Session 16 of the tutorial should provide you with the information you need.

The tutorial contains a series of sessions which are basically a walk-through guide to constructing the readers.
Each session comes with it's own examples BRGs, sample data, and exercises.

For more advanced usage and questions, the LDR User Manual (located under <Client Install Dir>/docs/ldr/LDRUserManual.pdf) should be consulted.


Hope this helps,

Tim.

NOTE: The first two sentences of Session 1 in the LDR Tutorial containing the installation instructions are now obsolete as of LAE 4.6, since the LDR no longer requires a separate installation.
