Description
During assignment, when the MS has established a L2/LAPDm on the new channel, the old channel is completely abandoned. Once we have received the ASSIGNMENT COMPLETE, we know that the assignment was successful and have to release the old channel.
Despite that, we try to do a "clean shutdown" of L2 on that channel by sending a RLL_REL_REQ, which will trigger the LAPDM instance at the BTS send a DISC to to the MS over the old channel - where we know nobody is listening anymore.
