From 7975ddf0ec2e59579331b5aa997e8057ae8d7cbc Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sun, 16 Oct 2016 23:44:16 +0200 Subject: RBS2000: re-establish any lost signalling links Contrary to standard A-bis, in the RBS2000 case the BSC connects the signalling data links (LAPD) to the BTS. In case one of them drop, we need to attempt to re-establish them. This requires libosmo-abis with Change-Id I07f0f79e0cda09766f357032ffb4e7ad643d448a Change-Id: I710b5af5d0acbdd3febd314849340f2adb7abd80 --- openbsc/src/libbsc/bts_ericsson_rbs2000.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/openbsc/src/libbsc/bts_ericsson_rbs2000.c b/openbsc/src/libbsc/bts_ericsson_rbs2000.c index a82893729..1d122eced 100644 --- a/openbsc/src/libbsc/bts_ericsson_rbs2000.c +++ b/openbsc/src/libbsc/bts_ericsson_rbs2000.c @@ -104,6 +104,7 @@ static int inp_sig_cb(unsigned int subsys, unsigned int signal, void *handler_data, void *signal_data) { struct input_signal_data *isd = signal_data; + struct e1inp_ts *e1i_ts; if (subsys != SS_L_INPUT) return 0; @@ -121,6 +122,17 @@ static int inp_sig_cb(unsigned int subsys, unsigned int signal, break; } break; + case S_L_INP_TEI_DN: + if (isd->trx->bts->type != GSM_BTS_TYPE_RBS2000) + break; + LOGP(DNM, LOGL_NOTICE, "Line-%u TS-%u TEI-%u SAPI-%u: Link " + "Lost for Ericsson RBS2000.
