DAHDI and LAPd errors

Dear Members, From the beginning I am having various LAPd related error messages with Nokia InSite and a DAHDI E1 card. The LAPd connection resets itself several times before a working OML and RSL connection is made. I don't know, maybe this is due to a change in the DAHDI code. I am getting lapd errors during the BTS initialization like this one: ^[[0;m^[[1;36mTue Jul 16 13:55:10 2013 <0005> bsc_init.c:91 shutting down OML for BTS 0 ^[[0;mTue Jul 16 13:55:14 2013 <0018> input/lapd.c:159 LAPD state change on TEI 1: NONE -> ASSIGNED ^[[0;mTue Jul 16 13:55:14 2013 <0018> input/lapd.c:212 LAPD Allocating SAP for SAPI=62 / TEI=1 ^[[0;mTue Jul 16 13:55:14 2013 <0018> input/lapd.c:223 k=1 N200=3 N201=260 T200=1.0 T203=10.0 ^[[0;mTue Jul 16 13:55:14 2013 <0018> lapd_core.c:292 Init DL layer: sequence range = 128, k = 1, history range = 2 ^[[0;mTue Jul 16 13:55:14 2013 <0018> lapd_core.c:229 new state LAPD_STATE_NULL -> LAPD_STATE_IDLE ^[[0;mTue Jul 16 13:55:14 2013 <0018> input/lapd.c:485 LAPD DL-ESTABLISH request TEI=1 SAPI=62 ^[[0;mTue Jul 16 13:55:14 2013 <0018> lapd_core.c:2171 Message DL-ESTABLISH-REQUEST received in state LAPD_STATE_IDLE ^[[0;mTue Jul 16 13:55:14 2013 <0018> lapd_core.c:1685 perform normal establishm.

For example - as I mentioned it earlier - DAHDI 2.7.x breaks the compatibility with OpenBSC due to the changed addressing scheme. BR, Csaba
