TESTING EXAMPLES
Prior to actually using the TSU ACE 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:
• Send the pattern from one end and loop back the far end.
• Send the pattern from both ends and check at both 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.
