G.703/13 Output Module

Operational Check

With power applied to the shelf, install the G.703/13 Output module in the
appropriate slot and verify that the POWER indicator is lit. This indicates that the
module is receiving power and the module power supply is working.
Verify that the module is receiving the input signals by observing the A and B INPUT
FAULT indicators. For Locked operation and with two references applied, both
indicators should be off.
If at least one functional Frame Generator is installed, the OUTPUT FAULT indicator
should go out within eight seconds after the G.703/13 Output module is installed. If it
does not, an output may be bad or has an excessive load connected to it (example,
shorted). The indicator will remain on if there is no reference connected, since there
can be no outputs.
Note: The module indicators may take a few seconds after
installation to reach proper operating status.
