Hi, I can't alignment a libss7 Asterisk with a TDM switch (Huawei/UMG) because the link doesn't pass the "PROVING" state. All configurations are correct according from telco, but I always get the same logs: Starting link 1 Link state change: IDLE -> NOTALIGNED Len = 4 [ ff ff 01 00 ] FSN: 127 FIB 1 BSN: 127 BIB 1 >[0] LSSU SIO Len = 4 [ ff ff 01 00 ] FSN: 127 FIB 1 BSN: 127 BIB 1 <[0] LSSU SIO Link state change: NOTALIGNED -> ALIGNED Len = 4 [ ff ff 01 02 ] FSN: 127 FIB 1 BSN: 127 BIB 1 >[0] LSSU SIE Len = 4 [ ff ff 01 02 ] FSN: 127 FIB 1 BSN: 127 BIB 1 <[0] LSSU SIE Link state change: ALIGNED -> PROVING Len = 4 [ ff ff 01 03 ] FSN: 127 FIB 1 BSN: 127 BIB 1 <[0] LSSU SIOS Link state change: PROVING -> IDLE Anybody knows why I can't pass this state and get the link in ALIGNEDREADY / INSERVICE?
