It's very good, and very understandable. > 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 > T4 expired! > Link state change: PROVING -> ALIGNEDREADY > Len = 3 [ ff ff 00 ] > FSN: 127 FIB 1 > BSN: 127 BIB 1 >>> [0] FISU > > Len = 3 [ ff ff 00 ] > FSN: 127 FIB 1 > BSN: 127 BIB 1 > <[0] FISU > > Link state change: ALIGNEDREADY -> INSERVICE > [0] MTP2 link up > Len = 9 [ ff 80 06 c0 04 80 f0 02 17 ] > FSN: 0 FIB 1 > BSN: 127 BIB 1 >>> [0] MSU > [ ff 80 06 ] > Network Indicator: 3 Priority: 0 User Part: NET_MNG (0) > [ c0 ] > OPC 3010 DPC 4 SLS 0 > [ 04 80 f0 02 ] > H0: 7 H1: 1 > Message type: TRA > [ 17 ] > > Len = 20 [ ff 81 11 c1 04 80 f0 02 11 a0 32 35 36 34 32 38 36 32 38 38 ] > FSN: 1 FIB 1 > BSN: 127 BIB 1 >>> [0] MSU > [ ff 81 11 ] > Network Indicator: 3 Priority: 0 User Part: STD_TEST (1) > [ c1 ] > OPC 3010 DPC 4 SLS 0 > [ 04 80 f0 02 ] > H0: 1 H1: 1 > [ 11 ] > > Len = 25 [ ff 80 16 c1 c2 cb 00 00 11 f0 aa aa aa aa aa aa aa aa aa aa > aa aa aa aa aa ] > FSN: 0 FIB 1 > BSN: 127 BIB 1 > <[0] MSU > [ ff 80 16 ] > Network Indicator: 3 Priority: 0 User Part: STD_TEST (1) > [ c1 ] > OPC 3 DPC 3010 SLS 0 > [ c2 cb 00 00 ] > H0: 1 H1: 1 > [ 11 ] > > Len = 25 [ 80 82 16 c1 03 80 f0 02 21 f0 aa aa aa aa aa aa aa aa aa aa > aa aa aa aa aa ] > FSN: 2 FIB 1 > BSN: 0 BIB 1 >>> [0] MSU > [ 80 82 16 ] > Network Indicator: 3 Priority: 0 User Part: STD_TEST (1) > [ c1 ] > OPC 3010 DPC 3 SLS 0 > [ 03 80 f0 02 ] > H0: 1 H1: 2 > [ 21 ] > > [0] --- SS7 Up --- > Len = 14 [ 80 83 0b c5 04 80 f0 12 01 00 17 01 01 17 ] > FSN: 3 FIB 1 > BSN: 0 BIB 1 >>> [0] MSU > [ 80 83 0b ] > Network Indicator: 3 Priority: 0 User Part: ISUP (5) > [ c5 ] > OPC 3010 DPC 4 SLS 1 > [ 04 80 f0 12 ] > CIC: 1 > [ 01 00 ] > Message Type: GRS > [ 17 ] > --VARIABLE LENGTH PARMS[1]-- > Range and status: > Range: 23 > [ 01 17 ] > > > What is happening on my SS7 link?
