Example Operations
TESTING EXAMPLES
Before using the TSU 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:
• 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 (511). 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 pattern is always sent in the occupied
channels.
