hi,
 
tests with layer 3 pointed out a problem. when i select a cell, i get
updates of system informations, paging requests and immediate
assignments. after about half an hour, i get some corrupt frames. i
don't know yet what is wrong.
 
1. is the communication between the layer 1 and layer 2 (over serial
link) secure?
2. i must be sure that a message between layers always are:
 - never get lost (except unit-data or data when connection is aborted)
 - never are corrupt
 - received in the order they are sent
3. does layer 1 drop (bcch) frames, if they have biterrors? (as it
should do)
