Yes Ers. But I don`t know what does it mean?? Do you use Tems Investigation?? I know how to use the program, but there are many “Alarm voice” that I don`t know!
The RACH channel is used to transmit the “CHANNEL REQUEST” message.
The channel is called “random” since the mobile chooses the call TS randomly.
This means that there is a risk of collision.
Collisions are resolved by retransmission after pseudo-random delays.
