Hello guys.
I have a special case in a 2G NSN sector with 2 TRX, all TSL were in FR mode, I reconfigured the TSL from TCHF to TCHD. Since that moment. TCH blocking begins. previously TCH blocking was not present.
The counter that increased after this reconfiguration was 001122 / TCH REJ DUE REQ CH A IF CRC, I made the rollback and returned all TSL to TCHF and TCH blocking and counter 001122 activity stops.
Does anyone know why this behavior?.
This is the explanation of the counter 001122: Number of requests for TCHs that are rejected because of a mismatchbetween the types of the requested channel and the A interface circuit, whether queuing occurred or not.
I made other reconfigurations of TSL in others sectors, and this behavior never happened.
Any comments are welcome.
