5.1.3 Downlink
Confirm that there is a signal at the expected frequency and strength from the base station. If
this is not present then the fault may lay outside the system. To confirm this, inject a downlink
frequency signal from a known source at the master site BTS input and check for output at the
remote site feeder output.
If a signal is not received at the output it will be necessary to follow the downlink path through
the system to find a point at which the signal is lost. The expected downlink output for the
given input can be found in the end-to-end test specification.
5.1.4 Uplink
Testing the uplink involves a similar procedure to the downlink except that the frequencies
used are those transmitted by the mobile equipment.
5.1.5 Checking service
Following the repair of any part of the system it is recommended that a full end-to-end test is
carried out in accordance with the test specification and that the coverage is checked by survey.
It is important to bear in mind that the system includes a radiating cable network and base
stations that may be faulty or may have been damaged.
