Ericsson End of Selection Code

Hi Shibli,

EOS - End of Selection Codes.

For the MSC/VLR/SSF/gsmSSF EOS you have to look the CODS (MML commands), PODS (Printouts) and OPI (MML operations) documentation set.

MML is the man machine language that is used by the Switch (Stored Program Control) node.

End of Selection cause codes helps to understand how a telephony session was released. The generated cause code will help with trouble shooting switch resources, circuits, connections, signalling, etc..

As EOS (cause codes) captures the nature of the call release it can be used as an input for any planned CEM system solution.

Information from the Network will need to be captured, stored and processed so that "insights" can be created.

Does anybody have experience with Ericsson's MSC EOS? I would like to know if the end of selection codes can be use for quality tracking of core problems.
