MSDL installation for all systems

Insert the MSDL card into the selected card slot of the module
following the card guides.

Observe the red LED on the MSDL faceplate. If it turns on, flashes
three times, and stays on continuously, the MSDL is operating
correctly but is not yet enabled.

If the LED turns on and stays on continuously without flashing
three times, the card can be defective. Go to step 8.

Connect the appropriate cable between the NT6D80 and the PRI
card MSDL interface.

Enable the MSDL card in LD96.

Unplug the MSDL card and reinsert it. If the red LED still does
not flash three times, leave the card installed for approximately 10
minutes to allow the card to be initialized.

After 10 minutes unplug the card, reinsert it and if the card still does
not flash three times, the card is defective and must be replaced.
