Chapter 4. Example Operations

TESTING EXAMPLE

If the example operations in the preceding pages were followed, the TSU 600 is completely configured and capable of passing data from the PBX and the DTE. Prior to actually using the configuration to pass voice and 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 loopback 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 (QRSS). The second is a check of the DTE port.

Network Interface Test

The Network Interface Test can only be run when a full T1 is available (i.e., this cannot be used over Fractional T1).

At the Main menu place the cursor on 4)TEST with the number 4 or by scrolling. To activate the menu, again press number 4 or Enter.

The unit displays the first two Test submenu items with the cursor on 1)NETWORK TESTS (see Figure 4- 15). To activate, press number 1 or Enter.
