Registration Call
WHY?
Test whether the mobile sets up a registration answer to
the calling base station.
Requirement
The mobile is not in an analog or digital traffic channel.
In any other case drop the call with
{RELEASE}
.
The mobile is not in test mode.
HOW?
Make the general test preparations.
Press
{REGISTER}
in the basic test mask. The Communi-
cation Test Set sends a registration call to the mobile
and waits for the answer.
If the mobile fails to respond to the registration call, halt
the test with
{STOP}
, enter a new, valid home system
number and start the test again.
