From 8b571ee2e736b6a99b2f3dfd2fd98ba24960e415 Mon Sep 17 00:00:00 2001 From: Philipp Maier Date: Mon, 30 Jan 2023 12:38:30 +0100 Subject: [PATCH] pcuif_proto: add indication to communicate E1 parameters osmo-pcu will also support GPRS via E1 timeslots in a BSC co-located setup. To avoid duplicate configuration the BSC has to communicate the E1 parameters (which TS, SS etc.) to the PCU. Lets add a new primitive to do that.
