TESTING EXAMPLES
Before using the ESU LT to pass data, it is recommended to
run tests on the circuit. Testing consists of sending a test
pattern from end-to-end and checking for errors in the
pattern. There are two types of tests used to accomplish this:
• Loop-up the far end and then send a test pattern.
• Send a test pattern from both ends and check at bot
ends.
Far End Looped Back Test
Two types of tests can be executed with the far end looped.
The first is a check of the network and the network interfaces
at both ends. The second is a check of the DTE port.
Network Interface Test
The Network Interface Test can be run with any channel
setup because the 511 and QRSS patterns are always sent i
the occupied channels.
