Use the tables in Section 2, Microwave Path Engineering Basics, of this manual to select the
proper free-space attenuation value (in dB) based on the estimated length of the microwave path.
Remember to subtract both antenna gains (local and remote) from the attenuator setting.

10. Test the installed modules by performing the following:
11. Command a link loopback on the remote TRACER 6420 unit and run a test pattern from the
connected T1 equipment. This will verify the data path across the RF link.
Installing/Configuring T1 Hardware
1. If possible, attach any or all of the intended T1 hardware to the TRACER 6420 units using the
same workbench setup. This step offers the perfect opportunity to configure your T1 hardware for
proper functioning with the TRACER 6420 hardware.
proper functioning with the TRACER 6420 hardware.
2. To significantly reduce the probability of an unsuccessful field installation, resolve any remaining
T1 equipment-to-TRACER 6420 configuration issues before field installation. See T1 Interface
Alarm LEDs on page 105 for more information on resolving T1 interface alarm conditions.

the same workbench setup. This step offers the perfect opportunity to configure your Ethernet
hardware for proper functioning with the TRACER hardware.

4xT1 Module
Initiate a line loopback on the local TRACER 6420 unit and run a test pattern from the connected
T1 equipment. This will verify the connection between the T1 equipment and the local
T1 equipment. This will verify the connection between the T1 equipment and the local
TRACER 6420 unit.
Quad Ethernet Switch Module
Connect a computer (or Ethernet test equipment) to the TRACER 6420 Ethernet interfaces.
Perform a “ping” from one test station across the wireless link to another test station connected to
the remote TRACER 6420. This will verify the data path between the test equipment and the
TRACER 6420 unit.

External pattern generators are required to test data path integrity. An T1 BERT tester is
suggested.
