Hi,
I can give u the way to test the cic between two exchanges if u have a siemens switch.
For that u need to create code receivers of type RMCTC on position 0 of the ltg carrying the CCS-7 trunks where u want to carry out the test. Then enter the trunks in maintenance bloking using the command ENTRTMBLK and then test the cic using the command TESTC7TRUNK. See what result u get. If u get the message
“Allocation of CIC is same in both the exch” then cic in both exch is same else u will have to chek the allocation or pathing of the E1s.
