fixeria has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/38578?usp=email ) Change subject: library/s1ap: rework {ts,tr}_S1AP_RABSetupRsp templates ...................................................................... library/s1ap: rework {ts,tr}_S1AP_RABSetupRsp templates 3GPP TS 36.413, section 9.1.3.2 "E-RAB SETUP RESPONSE" defines the following two IEs as optional: * E-RAB Setup List IE: 0..1 in the Range column means that it can either be omitted (0) or included only once (1); * E-RAB Failed to Setup List: 'O' in the Presence column. Our templates for this S1AP PDU require the former to be a value (as if it was mandatory) and do not allow passing the later.
