Section 2 Installation

REMOTE BERT

The TRACER includes a Bit Error Rate Tester (BERT) to verify that the installed system is operating correctly. When the “Remote Test” button is pushed on the local BBP, the remote end will send a BERT pattern for approximately ten seconds. The “Remote TST” indicator will turn yellow and remain on for the duration of the test. If no bit errors are detected, the “Remote TST” indicator will turn off. If any bit errors are detected, the “Remote Fail” indicator will turn red. This test should be run after the radio link has been aligned. If the test fails, refer to Section 4, “Troubleshooting,” for guidance.

ALARM CONTACTS

Two classes of alarm, MAJOR and MINOR, are provided. A MAJOR alarm is signaled when the microwave path is not operational. A MINOR alarm is activated when any of the following conditions are detected at one of the E1 interfaces:

Loss of Signal

Code Violation

CRC error

Framing Error

Remote Error

UA1

Both normally-open and normally-closed contacts are provided for each alarm class. Access is provided by a six-position terminal strip on the baseband processor.
