8.3 Making Test Calls on the Air Interface
This section describes how to make test calls on the air interface. The tests are
performed from the RBS site to verify that all TSs on all TRXs work properly.
The test calls are performed by using a Test Mobile Station (TEMS). See TEMS
Investigation GSM Manual in the TEMS Kit.
Note: It is important to test all TCH-TSs to ensure full capacity.
All the test calls should be made from a distance of at least 50 m (164 ft) from
the antenna system. See Figure below.
