ST2400A SDH Test Set User Manual
General Functionality Verification
This section of the User Manual tests the functionality of the unit. The procedure consists of eleven
sections in which the functionality of the unit is verified.
Note: The procedure assumes you are
proceeding in sequential order.
Before beginning the procedure, you must set the unit to factory
default settings to ensure that you are starting the procedure from a known state. To default the unit to its
factory settings, follow the procedure below.
1.
On the front panel, press SETUP until the display shows the STORE/RECALL Setup menu.
2.
Using the LEFT/RIGHT cursors, select FACTORY DEFAULT and then press ENTER.
Note:
Whenever you make a change in a menu, the red LED within the ENTER key will flash. This
signifies that if you wish that change to occur, you must save it by pressing ENTER.
3.
The display now reads “Restore Factory Default?”. Using the LEFT/RIGHT cursors, select YES
and press ENTER. The display flashes a message stating that all settings have been returned to
factory defaults, then it returns to the REPORT/TEST Setup menu.
4.
Once the factory default settings have been restored, observe that all the error lights within the 2.4
Gb/s STATUS section of the receiver front panel are lit. This is because the default settings set the
laser to OFF, so the unit is no longer linked.
Now that the unit has been correctly defaulted, you may continue with the next section of the procedure.
STM-16 (SDH) Quick Setup
This section of the procedure verifies that the SDH mode for STM-16 is functioning properly. The quick
setup places the unit into a default mode which selects specific settings for the unit. These default settings
are preprogrammed and therefore consistent from unit to unit. Leave everything as it was in the last
section of the procedure. There are nine steps in this section of the procedure. Before any connections
are made, use the optical cleaning kit to clean the cable ends, the attenuator ends, and the optical
connectors on the front panel of the unit.
Note: The last section of the procedure provides an
equipment list and simple instructions on how to clean the optical connectors.
1.
On the front panel, remove protective covers from the 2.4Gb/s IN and OUT connectors.
2.
Connect a fiber-optic cable with an in-line 15db attenuator between transmitter side (left side) 2.4Gb/s
OUT to receiver side (right side) 2.4Gb/s IN.
3.
On the front panel, press SETUP until the display shows the Auxiliary Setup menu and press ENTER.
4.
On the front panel, press SETUP until the display shows the System Configuration menu.
5.
Using the LEFT/RIGHT cursors, select SDH and then press ENTER. The display then flashes a
message stating that the program is restarting (due to measurement mode change). Wait until unit
reboots.
