In case of SD congetion u will nt get SD because of unavailability of Channel element.
Reason:1) Improper LAC planning
2) HARDWARE Issue.
SD Drop takes place after SD allocation but before TCH allocation.
Reason:-1)Poor coverage
2)Interference
3)Abis link failure
There are some other reason for SD drop.
