Call from base station
Why?
!
See if the mobile station can receive a call.
!
Proper call setup is a requirement for further tests.
Requirements
!
Mobile station is registered ("idle updated") and not in a
call.
How?
!
Prepare for test (see section "General Preparations").
!
Select a BS-CALL type which is supported by the
mobile.
!
Press
{BS_Call}
in the basic test mask. The STABILOCK
calls the mobile station on the main control channel.
!
Answer the call (lift receiver or press PTT). STABILOCK
directs mobile station to the selected traffic channel slot.
The display shows "traffic channel" on the left-
hand side and measurement results on the right-hand
side.
"
The STABILOCK will set up a call to the MS under test according to the selected
type of BS-CALL (simplex, duplex, simplex direct through, duplex direct through).
If the mobile does not support the selected call type, an error message is
displayed and the call establishment is aborted. As a BS-CALL on full duplex
mobiles directly can be choosen in the basic mask, the former Special-1 entry
"002" is no longer needed
"
In semi-duplex mode, keep PTT pressed in order to maintain the call and to see
measurement results.
