Far End Looped Back Test
Network Interface Test
61200060L1-1
Testing Example
Prior to actually using the TSU to pass data, it is
recommended to run tests on the circuit.
The 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 loopback the far end.
•
Send the pattern from both ends and check at both ends.
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.
The Network Interface Test can be run with any channel
setup because the 511 pattern is always sent in the occupied
channels.
