When we finished the configurations between C&C08 switch with UA5000 by V5 signaling and after all it's ok but when we connect the E1's between both side by transmission it display an alarm)! EVENT MINOR 2008-02-03 16:10:54 ALARM NAME :V5 common control protocol timeou) and also when we reset V5 it's failed but when we loop E1's to our side(UA5000 only) V5 it was ok.
! EVENT MINOR 2008-02-03 16:10:54 ALARM NAME :V5 common control protocol timeout)
After several trails and check with support staff about problem that E1's between C&C08 switch with UA5000 sites became unavailable when connect to each other by transmission but when we loop it in DDF of the E1's for each side alone became ok, but finally we check configurations in C&C08 side also in UA5000 side part by part so we found that UA5000 side have CRC4 function but E1's for C&C08 side don't give it this CRC4 so after we MOD SPME1 and add CRC4 function (MOD SPME1: FN=4, BN=2, HT=C842, SN=0, EN=15, CRC=YES;) directly all E1's become Normal working from Unavailable state.
When we check with transmission side about E1's state and parameters that have relations for the E1's configurations and after several tests and trail from UA5000 and C&C08 switch until we found that UA5000 side have CRC4 function but C&C08 switch side as other exchnage E1's we don't add this function so we conclude the problem of the E1's it is in this function of the E1's.
