From 553535f87b490a8b8a2ab2633417ab7c286907bd Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sun, 17 Dec 2017 13:35:52 +0100 Subject: Add 'osmo-bts-omldummy' to bring up only OML without RSL This is used only in integration testing, where in the TTCN-3 testsuite we currently have no A-bis OML implementation, but only a RSL one.
