Have you received error messages in your Cisco routers that are not documented anywhere? Welcome to the Cisco-ErrorMessage-Decryption club.
ISDN Se0/0/0:23 SERROR: Pri_Activate_L2: BAD states = 0, 6; IDBS_UP 4
and sometimes BAD states 0,0. Any ideas anyone?
No, it's not SS7, it's a normal PRI and I'm not checking a SLT.
