( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/20385 ) Change subject: BSC_Tests: introduce TC_tch_dlci_link_id_sapi for OS#3716 ...................................................................... BSC_Tests: introduce TC_tch_dlci_link_id_sapi for OS#3716 The aim of this test case is to verify DLCI / RSL Link ID conversion for MO/MT L3 messages on SAPI0/SAPI3. In particular, the test suite verifies the following scenarios: - RSL -> BSSAP: - 16 MO messages on FACCH/F with SAPI0, - 16 MO messages on SACCH/F with SAPI3; - BSSAP -> RSL: - 16 MT messages on FACCH/F with SAPI0, - 16 MT messages on SACCH/F with SAPI3.
