  • Cisco Employee,

You need to runn the following debugs on the SLT to determine why MTP2 is down


From the intagrated SLT send the following commands and debugs:


deb ss7 mtp2 back 0

deb ss7 mtp2 iac 0

deb ss7 mtp2 lsc 0

deb ss7 mtp2 txc 0

deb ss7 mtp2 rcv 0

deb ss7 mtp2 aerm 0

deb ss7 sm session 0

As mention earlier in the thread please verify the session-set is up and running.


Please verify that before troubleshooting the actual mtp2 and signaling channel.


If that's done follow this procedure:


1. Restart AS and PGW

2. Verify netindicator

3. Recalculate PC

4. Verify SLC for the particular link

5. Verify timeslot on the C7iplnk

6. Verify Serial interface

Ex:


!

interface Serial7/0:0

no ip address

encapsulation ss7

channel-id 0

!

7. Check E1/T1 controller


ex:


!

controller E1 7/0

framing NO-CRC4

channel-group 0 timeslots 1

pri-group timeslots 2-31 nfas_d primary nfas_int 10 nfas_group 0

!
