TESTING EXAMPLE

Prior to actually 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 accom-

plish 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. Select Test from the Main

menu (see Figure 4-1).
