S2-001484 from AT&T: Template for call flows
AT&T proposes a template for drawing the flow diagrams which allows to clearly show the alternatives when optional elements (e.g. firewalls) are used or not.
Discussion: Lucent stressed that the flows are stage 3 and then have to be handled by N1.
It was stressed that the tool is valid as long as the alternatives are not too different in term of flows, but in some cases it might be preferable to have two different figures.
Conclusion: Approved. The usage of the figures (one or many) to be decided on a case by case basis.
